Unable to renew IP address. - [FIXED]

[StevieRay]

I am unable to renew my IP address.

I am using a wireless router...my laptop with the wireless card works, however, my computer that is hard wired to the router does not work.

I re-installed XP and since then it has not worked...but I have downloaded and re-installed all the proper drivers.

I have gone to the command prompt and tried releasing and renew the address and it will not work. I have also tried unplugging the router and modem and hooking it all up agian and this did not work. I also tried hard wiring the computer directly to the modem and this did not work.

Any suggestions.

Thank you.

[phishhead]

do you have dhcp enabled on the router? do you have a static ip setup up on your pc?

[lynchknot]

in services do you have DNS service enabled? What error message do you receive? I have the service disable because I have my individual apps do the look up. However, if I want to renew my ip I have to remember to turn DNS back on or I see this

[StevieRay]

I am not sure if I have DNS service enabled. I am not really savvy when it comes to this...the only reason I knew about the other ways to try and fix my problem was because my friends tried to help or I looked online...could you tell me how I would know if my DNS service was enabled??? Thanks so much- Andrea :o

[StevieRay]

In reply to Phishhead about the static ip...my one friend tried creating a static ip...but this did not work either...
In reply to to Lynchknot, the error message I'm getting when I hit "repair" is "Unable to renew IP address" .... Once again, thanks so much for trying to help me out-this is so frustrating! :)

[lynchknot]

You can go this route - then to DNS client

http://i132.exs.cx/img132/4907/serv4vb.jpg (http://www.imageshack.us)

Or go the long way: Control panel/admin.tools/services/DNS client. if it's disabled=right click/properties - then start it.

But really It should not be off unless you or someone turned it off. It is on by default.

[StevieRay]

Yep, as you predicted, DNS client is enabled...actually everything in the list under services says "started" next to it. Any other ideas????? :)Thanks!

[lynchknot]

power cycle. unplug your modem power and the router power for 10 minute or so. Plug modem power back until all usual lights light up then plug power back into router.

[StevieRay]

Hey, I unplugged modem and router like you said. I had it unplugged all day, then I plugged it back in...still doesn't work :( Help!!! Thanks!

[cash_site]

Check the settings on your Wireless router...

[lynchknot]

or bypass your router to see if you pick up an IP - then you know it's your router....maybe.

[StevieRay]

I just spent about 2 hours on the phone with a tech from Comcast. He had me unplug the modem and router, and then plug the modem right into the back of my computer through the ethernet port.
He went through basically everything with me, checking to make sure I had all my settings correct. Where the ethernet is plugged in, it is lit up (orange) and it blinks. Under Local Area Connections, it is enabled. The status says it is connected and working properly. But once again, when I click repair, I still keep getting error "Unable to renew IP address."
The tech told me that he's seen this problem a million times, but the Local Area Connection is usually disabled, unplugged, limited, something like that...but never enabled. He didn't know what else to tell me because he went through everything he knew to go through.
Another thing, I know it is not the ethernet cable or the card because the USB port doesn't work either- I get the same error message.
And I know it is not my modem, cause obviously, I can get online with my laptop.
I don't know what to do!!!! :( Thank you so much Steve (right?) for trying to help me? Any more ideas??? Haha

[lynchknot]

from left field - Are you using a software firewall? Chck to see if your lan setting are correct. chk your router setting as cash suggested as well.

[StevieRay]

Yes, I'm using Symantec...however, I disabled auto-protect. The Comcast tech had me check the LAN settings...how do I check my router settings, is it the routerlogin.com thing?...what should I be looking for (I don't think this is the problem as my computer won't connect even directly to the modem)...thanks so much for being so patient. I'm just getting really pissed off! I've been up all night for the past week trying to fix this! Thanks again!
Btw...I tried contacting you through AIM but you're not on, atleast I can't see you...it might be easier to talk through that :)
-Andrea

[lynchknot]

I rarely fire up my IM. Sometimes I have to recreate rules for my browser with software firewall (delete entry for browser then let it prompt me again) when I mess around with my connection - or I can't connect at all.
To inspect my router settings, for my router, I type 192.168.0.1 into the url field and router settings pop up. Find your router's IP. What happens at CMD prompt when your type ipconfig /all - should give you your router IP from there you can enter into url field. I would check your software setttings first though

[StevieRay]

What software settings do you want me to check-Symantec? What should I check on it and how should I go about checking the settings?
I tried to check my router settings but I keep putting in 196.168.1.108 and it doesn't go anywhere...so I don't know what's up with that????
Thanks again!! :)

[lynchknot]

I don't know about Symantec - other than most people I met don't use it. Try: 196.168.1.1

[StevieRay]

Ok, well I can't find my router settings...it's not working, I don't know why but I will have my friend check it out Monday. However, I was wondering if the problem could be with my chipset and network (broadcom) drivers...if i wanted to reinstall those, how would i do that?? Thanks for dealing with me-I'm a pain in the butt! :)

[lynchknot]

What brand of router are you using? Wait... can you get online with your laptop using cable - not wireless?

Hello TZ experts (me just a wannabe), time to chime in?

[Curio]

Your laptop uses wireless but it is assigned an ip from the same address pool by the router - run "ipconfig /all" on the laptop and look for the dhcp server - that will be the ip of your router. If you can get a knoppix or PEbuilder disk try booting the desktop system from that and see if the network card is recognised and works - this will isolate a hardware from a software fault.

[StevieRay]

Hey! Haven't been on in awhile- actually now my wireless isn't even working and when I try to hook my laptop right up to the modem, it still won't work. I've tried power cycling too-no luck. However, when I hit "repair" for my laptop...it doesn't give me the error message "unable to renew ip address." It says that it finished repairing and if I have any problems I should contact my ISP.
I contacted Comcast...they went through the scripted thing-he couldn't fix it. I am almost positive it is my ISP that is causing the problem...I think I'm going to call a tech to come to my house after Easter and make them fix this thing!
What do you think??? :o

[Curio]

That sounds very much like a faulty router, there is a lot of it about. Wireless routers at the moment seem to be in the realms of beta testing equipment. Only the expensive ones are very reliable and not even all of them.

[jambandgrl]

I have the same problem that yall are having, and people have been telling me over and over again to do the same thing that I have been hearing in this forum. I have been trying to get my wireless connection to work for months now and i keep getting the same error message. I have spent countless hours on the phone with "tech support" idiots from different continents and I still have a freakin cable running across my living room! :mad: I am using a cheap Belkin router. Could that be the issue?
Thanks!

[MelisP74]

My IP address won't renew and I don't have a router. Comcast says it's my computer with the problem.. not their service.. although I find it strange that my connection went out the same day they were having major problems in my area. But I can't even connect on AOL dialup now either... wonder if the comcast bad ip address affected aol dial up??

[PIPER]

what kind of puter do you have?.....it is possible that your problem is linked to the nic....are u using the one on the MB or a seperate card....sounds to me like it might be a Dell.....oops did I say that....if it is you may need to reinstall your driver if you have done a reformat.

[MelisP74]

My computer was built almost 3 years ago by my roommates mom, so its not a dell, its not any brand. It has an AMD athlon and 256 ram.

I bought a new NIC, I think i stuck it in the PCI slot??

However, Comcast tech came again today this time with the laptop (why he didn't have it the first time I don't know) and his laptop couldn't get online either... so he called his boss who swears there is a signal coming here, so the boss has to come for himself tomorrow.

So now I know it is comcast, but in the meanwhile why would it affect my dial up connection? I installed AOL 9.0 for dial up and it doesn't work. AOL said maybe a virus, but nothing comes up. Could the comcast problem have affected my comp ability to go online with a phone modem???

[lynchknot]

Comcast (then ATT) could not install service for me. They installed the cable to the house but gave up on my computer. I grew impatient and installed (connected) myself. They waived installation fees since I did it.

Perhaps running sfc /scannow, repair, or one of those Winsock - tcip(?) repair apps will work.

Edit * opps, I reread your post so nevermind!

[jimlocke]

StevieRay, I just a few minutes ago had the EXACT problem you did with a Netgear Wireless Card (wasn't sure if it was just the card or also the Netgear wireless router).

Tech support (which was yet another experience because of it being offshore, just like Linksys support was) ended up suggesting a driver update for my Wireless card.

After some fiddling (removing the card, uninstalling the drivers, then installing the driver update, followed by plugging and unplugging the card a few times after windows booted), I got a wireless connection back!

One more thing I just thought of we did also: I actually set the region on the wireless router, which apparently was not set. Also, the tech guy had me add a new SSID (Network name). After updating the driver for the wireless notebook card, it detected the new network name ("JIM" in my case), and finally was happy.

Email me at jimlocke@charter.net if you want any more details.
Cheers!

[MelisP74]

Well it is now fixed! Someone directed me to a site that has a download of a WinSock Fix. So I downloaded that on a floppy on a friends computer and ran it in mine. Ta da, now able to get on AOL dial up. And my instant messages on AOL and AIM are sent immediately whereas before they would lock and freeze for a few seconds before they were sent. The winsock fix updated my IP address but I still couldn't get an internet connection from Comcast. However AOL dial up finally worked. As for my cable connection... Comcast fixed it 5 days later.

[lynchknot]

You did not see my post? You could have easily googled for it: perhaps...or one of those Winsock - tcip(?) repair apps will work :p - ok, it was a stab in the dark but I'm glad you got it working. :)

Sorry I may be good at using a computer but I know nothing else about them! So your post didn't really make any sense to me because I didn't know what to look for plus without the internet connection I couldn't search google, I had a hard enough time using someone's computer to get on this message board, my cousin happened to send me the winsock file and told me to run it... But you were right and it fixed it!

[rokenn3]

OK people. I am having the same issues. I thought it was the Linksys router or the cable at first but it was not.

My issue:
1 Computer will not access the internet or my other computers. Getting limited or no connectivity icon.

My Setup:
3 PC's and 1 laptop.
2 PC's running Win 2k Pro and 1 running XP
Laptop running XP
Laptop connects wirelessly. Other 3 PC's are hardwired to router.
Problem PC is running XP.

What I have done so far
1. Tried setting static IP addy (192.168.1.....)
2. Tried Ip release, renew, etc.
3. INstalled new ethernet card
4. Tried WinsockXPfix.exe
5. Tried reinstalling TCP/IP (nettcpip.inf)
6. Ran AdAware, Spybot, Charter security Suite, etc.
7. Disabled SP2 Windows firewall.
8. Downloaded sp2connect fix (includes Patch kb884020, FixReg app)
9. Have changed cables.
10. Have power cycled entire system.

I believe I have done a few more things as well, spoken to Linksys tech support for 2 hours, Charter Cable tech support for some time and searched every forum I know. Googled the problem but NOTHING is working. Outside of buying a new computer or re-installing XP (which would be QUITE a process for me) is there anything else I am missing that I could try? Someone HELP please!! :eek:

[mercuryeyes]

Okay listen carefully guys, i just joined today because 15mins ago i had the same problem, i.e unable to renew ip.
so i google for the problem and found this site. It turns out that the program to fix the problem was "winsock xp fix".
you can get it from http://www.snapfiles.com/get/winsockxpfix.html

Im not sure if it will work on earlier OS though. i dont mean to be repetitive, but im just here to clarify why the fix worked.
the problem was caused by adware and spyware. And if anyone of us ran a spyware program, we must have deleted or corrupted the original winsock files on our comps.
what winsock did was replace those missing files and automatically released and renewed the ip address.
I was just happy to note that the file could fit on an empty diskette 1.37mb otherwise i would have been royally screwed.
I dedicate this entry to StevieRay who must have went through hell to fix her comp, God knows i didnt go through that much yet lol, and to lynchKnot for being so helpful. you two inspired me to join. il try to help others if i can.

:)
thnx.

[mercuryeyes]

oh and one more reason is if u ran a "registry editor", or registry fixer.
Your winsock registry files were deleted
and winsock xp fix restores it.

[rokenn3]

I have tried Winsock Fix already. See my step 4 above. I have run Spybot, AdAware, AdwareAway, Charter Security Suite etc. Still not working. Anything else to try?? :confused:

How about trying another router and/or modem or maybe it's a bad ethernet plug socket? Have you tried switching "roles" with other computers? Ok reread you post. So it's a wireless bug eh? Is there a chance to try another wireless computer to verify there is no signal?

[rik]

From a command prompt try "netsh winsock reset catalog" withoutthe quotation marks. After that might also try reinstalling TCP/IP again.

[Curio]

Now is a winsockfix available for all MS OS see www.subratam.org (http://www.subratam.org/main/index.php?option=com_content&task=view&id=19&Itemid=41) your move should be to boot from a knoppix disk and see if it works that way - this proves the fault either hardware or software and so you can then progress rather than just re-installing TCP-IP a hundred different ways.

I am having no problems on my wireless computer. It is only ONE of the hardwired computers. I've tried everything I can find or know of.
I'm going to try the winsock catalog deal when I get home and let you know how that works.

Curio, ummmm, HUH?? I didn't understand man. Knoppix?? Not sure what that is. Explain please! I'll check that subratam website. Better not be a virus :rolleyes:

[lynchknot]

knoppix is a bootable Linux CD with networking

Hi, I just registered on the forums because I am having similar problems with my broadband connection and you guys seem very knowledgable on this subject. Maybe you can help.

Ok, so here's my problem. I just formatted my gf's sony vaio pcv-rs510 and installed winxp professional on it. I downloaded all the drivers and utilities from the vaio website for the pcv-rs510 and installed them. I do not have any hardware conflicts. Windows loads up just fine, however, there is no internet connection when the computer loads - the little icon with the two computers and the flashing screens doesn't appear in the system tray. BUT, after about one minute the hard drive becomes active and the icon previously mentioned appears. From this point, I am unable to load a webpage in internet explorer - when I try I get the error message: "Internet Explorer could not open the search page". I cannot ping anything, I get the error message: "Ping request could not find host <hostname I entered>. Please check the name and try again". When I check the status of the internet connection, I see I am sending packets but not receiving them. My IP address begins with 169. When I try to repair the connection, I get the error message: "The following steps of the repair operation failed: Renewing the IP address. Please contact your network administrator or ISP". I also notice that I have 4 svchost.exe's running in the task manager. One other thing is that I have a 1394 Net Adapter installed in addition to the network adapter that is being used for my broadband Local Area Connection. The 1394 Net Adapter has its own network connection entitled "1394 Connection 2". I am 100% sure there is nothing wrong with my switch that the computer is connected to because I am posting this message right now on my laptop which is plugged into the same switch. Also, the broadband connection on the vaio worked fine before I formatted its hard-drive. I also tried the winsockfix which also did not work!

Thanks in advance for any help you guys may offer.

[Curio]

If your adapter IP settings are in the 169.254.x.x range that is the APIPA range which means the network card is not being configured by the router for some reason. You should try setting the network adapter IP address up manually in the same range as your working connection uses (usually 10.0.0.x/8, 192.168.x.x/24) and with the gateway address the same. If that works then you have proved the adapter OK (and you could continue to use it that way) and you can then move on to the software configuration.

[lynchknot]

I've had similar error messages (when trying to repair) when DNS client is disabled or not started in Services (it's usually disabled since I have DNS on a per-application basis) - so I have to enable it to repair

Hi all: First post. Can't believe how common this problem is.

I’ve been struggling with my wireless connection for almost two weeks, could sure use your help.

Setup: Win XP Pro > SBC DSL > Westell modem > D-Link 624 router (NIC Intel PRO/100)

System installed easily, and has performed flawlessly for about three months. Two weeks ago the power was disconnected inadvertently from the router, lost internet connectivity altogether.

A couple of hours with an SBC tech got me back up with a connection (through WAN PPPoE Miniport), but no-go on wireless ever since. LAN connection says ‘Limited connectivity’. ‘Repair’ will not renew the IP address.

Here’s a printout of ipconfig (when connected directly through modem only, no router):

Here’s what I’ve tried so far (after cables and connections):
1. Update router firmware
2. Hard reset
3. Reconfigure (I can see the router and change settings, but doesn’t help)
4. Check DNS enabled
5. ipconfig release/renew
6. Install XP patch KB884020, and update registry
7. Netsh winsock reset catalog
8. Uninstall/reinstall TCP/IP
9. Enable NetBIOS over TCP/IP
10. Disable WinXP and personal firewalls (TechMicro)
11. [Suspect corrupt Winsock], so Delete Winsock and Winsock 2, reboot
12. Install TCP/IP protocol, reboot
13. netsh int ip reset resetlog.txt
14. ipconfig /flushdns
15. ipconfig /sfc scannow

Any/all assistance sincerely appreciated.

Welcome to Techzonez jrjag53.

So you can get on the internet when directly connected to the modem. I assume that you have tried connecting to the router using both wired and wireless connections? I do see that you mention swapping cables, You can test all your cables by using them between the computer and modem without have the router in the mix. Just try 1 at a time to ensure they all work. With that eliminated, You already know that your ethernet card works because You are connecting to it and getting on the internet without the router.
1)The router may have gone out. I had 2 Netgears that did. Replaced it with a Belkin and haven't had a worry since.
2)You can try hardsetting the duplex on your ethernet card to a different duplex, i.e. 10mb/half duplex or 10mb/Full duplex. This may get it working as sometimes the "speed sensing" goes awry.
I don't feel that this is an OS problem because you are able to get online when bypassing the router.

[jrjag53]

Thanks, Rik. When connected through the router, my laptop can see the network (reads the SSID, and excellent signal strength), but no connectivity. Would this be the case if the router has gone bad? I also tried doing a wired connection to the router through another LAN port, but nothing.

[Curio]

Networking problems will drive you mental if you do not have 'known good' hardware to swap out once you reach the 'tried everything and it don't work' stage. If you can borrow a firiends router that's good but alternatively going to a place where they have a wireless network and connecting to it with the laptop proves the 'other' hardware so points the finger at the router.

Good luck.

[Mixer]

Hey there, been a lurker on the boards for a while and I had this same problem with both my wired and my wireless routers, and I found a solution, so this place has helped me out enough figured I'd post my solution. Anyway, I had connection when connecting directly from my ISPs modem to my computer but would lose it when I went through either of my routers. I did a lot of troubleshooting with this and after talking to some guys at work, this is what happened.
This is because your cable provider links your IP address to your MAC address (to keep people from stealing IPs), it's possible when resetting or hard rebooting your router the mac address was released and changed on the router and either there is none or a different one than what your ISP has in it's ARP table so it won't register you a new IP when you go through your router, but it will when you connect directly from the computer. This fix worked for me after 3 very long nights.

this is for winxp and a linksys BEFSR41 router ver.1 or 2. With a version 3 the
MAC address Clone tab is under setup.
go to network connections.
Double click on NIC card
Select properties
Select TCP/IP
Set the IP Address, Subnet Mask, Default Gateway, DNS servers
Hit Apply and close
Still in LAN staus window select support tab
Click details copy Physical (aka MAC) address
Then hit Repair
Close out this window.
Go to Linksys interface
Click the Advance tab
Select MAC Addr. Clone and enter the Physical Address in here and hit apply
Go back to Setup page and select Status
Hit DHCP Release and then DHCP Renew.
This should renew your IP Address and network connection (fingers crossed)

How did this happen? Well I was trying to see if my connection speed was slow because of my ISP or my router was doing something so I fiddled with a couple of things, release and renewed my IP on my router, I think I deleted the MAC address associated with this, not realizing it and voila, 3 long sleepless nights. Wasn't until someone at work told me about the ISP linking to my MAC address that it started to make sense. Hope this helps a few people out there.

[rik]

Only certain ISPs are doing this...the only one I can think of ATM is Comcast...They do cache MAC addresses and are charging for addititional IPs.

[Mixer]

The one I'm on is Rogers here in Toronto Canada. Just more reasons for me to switch to DSL.

[Curio]

I think most of the questions in this thread are DSL related but I agree with Mixer - a lot of cable modem connections do seem to need the 'Clone MAC' option set but then luckily all cable routers I have seen come with that option.

[PIPER]

GOOD POST MIXER.....very informitive.:)

[phishhead]

glad you fixed it mixer and welcome to the board officially I saw your intro thread. ;)

[Mixer]

Deathmetal, sorry, I'm not sure if I understand your request, I'm assuming you want more detail on setting the IPaddress, subnet mask, default gw and Dns servers?

The IP will be for whatever you have decided personally to give your PC in a SOHO enviroment (I probably should've mentioned that), the subnet mask will auto populate after you tab from the IP field.

The default GW will be the IP address of your router, 192.168.1.1 unless you've changed Linksys' default IP address.

The DNS servers would be the DNS servers that your ISP uses, you can usually find them listed on their website somewhere, or if you are directly connected to the ISP modem (not through the router) you can type ipconfig /all from a command prompt. Or if both those fail, call their tech support line and ask them. Hope that helps.

Hello all, I'm new here, sure I'll be around this place a bit, looks rather useful and I'm sure I can add a bit as well.

This thread helped me greatly in the past when I was having problems with a machine renewing its IP address and needed to do the winsock fix... I'm having a similar problem, but nothing I do seems to be helping.

Have a laptop that's been working fine wirelessly up until yesterday. I can't think of anything that has changed on the network or on the laptop. When it initially boots up, it will connect to the wireless router with no problems. After 2-10 minutes of being able to access the internet fine, a message pops up again from the system tray saying it's connected to the wireless network again. Any attempt to access any site, including the router itself through 192.168.1.1, from this point on fails. If you attempt to repair the connection, it will never renew the IP address. Ping attempts to the router fail. Localhost/127.0.0.1 still pings fine. If you reboot the machine, the same thing happens (connects fine initially, eventually loses connectivity w/o hope of repair). There is also a desktop that is connected wirelessly to the router in question and it has no issues at all. I reset the laptop to a restore point made a week+ before the network problems, didn't solve the issue.

When the laptop initially loads, ARP and ipconfig show:

Tried a static ARP table entry to no avail. Reloaded TCP/IP via the winsock fix mentioned earlier (deleting registry keys, rebooting, reinstalling protocol). Relooked over the Router's settings, everything looks fine. Checked system alerts/logs, doesn't show anything that I didn't already know. Settings all look correct best I can tell on the laptop... Driving me nuts and can't see any issues. Laptop has exact same problem when attached via ethernet to router, as well as to modem.

Service is Comcast, Modem is Linksys, Router is a RangeMax Netgear.

Any ideas? Or any additional information needed?

Thanks in advance for any assistance...

[Curio]

It sounds like a spyware or virus issue - many of the variants of the spybot worm exhibit a similar pattern of behaviour whereby they take over the network and stop anything else from being able to use it after a certain period. I would recommend trying the freeware versions of Bitdefender 8 and AdAware first then doing a manual setup of the network card if that finds nothing. After that it's HijackThis to look at the loading of all software on the startup and see if anything is a nasty.

Another thing that is often worth a try with wireless routers is to change the channel that the router works on - they all seem to come with a default of Ch6 and when everyone all around you uses the same they may interfere with each other. As your one also fails on the ethernet connection though it doesn't lok like that would be your issue.

[Dehcbad25]

I am feeling too lazy to read all of this, but it could put some extra bits.
Your ISP does keep an ARP table linking MAC and IP, plus DNS (ISP assings the DNS) To reconect in this case it is better to: (non-geek resolution)
1) Unplug power of cable\dsl modem and router (or PC if directly connected)
2) wait at least 30 seconds (this gives time to the ISP to consider the cable modem as disconnected, and thus releasing the record), sometimes you might need more, depending on how far you are from the central
3) plug in your DSL/cable modem. Let it go thru the whole boot process and registration, and wait until the online/activity light is on and shows ready (this varies between brands and types, but it could take several minutes, about 3~5 in mine)
4) connect your router. (plug the power) Let it go thru its boot process as well
5) you should be connected, if still have problems try the repair button
6) if this still did not work, go to Start>Run type cmd to open a command promtp and type "ipconfig /renew" (withouth the quotes).
if you get an error "Operation was attempted on something that is not a socket" then your Winsocks library are corrupted. (This is extremely common, since it is often caused by Spyware).
If this is your case, follow the steps in this site:

Well I see that this thread hasn't been posted in for awhile.

I've read the entire thread and when I get to the Knoppix test I also come up with no connectivity. When I'm in Windows I see that I'm connected at 100bps but I get the same "Limited or No Connectivity" error.

I was looking for advice on the fact that Knoppix also didn't have connectivity, does that mean that it's hardware and not 0/S related?

Here's some background:

3 - Wired Computers
1 - Wireless Computer
2 - Voip Routers
1 - Belkin Wireless Router (all wired and wireless computers but one work from this Router)

I've tried Release / Renew / Repair and a bunch of the suggestions on this thread.

Brand New - Just built computer that is giving me the "Limited or No Connectivity" problem. It connected fine earlier today I have XP Media Center, I've been working with it all day to try and get the capture card working in it and then about 2 hours ago this started... until then it connected fine.

I don't know a lot about Linux so I don't know how to test anything when I'm in Knoppix except that it won't get onto the internet using FireFox. (I tried to use MythTV and gave up and switched to Windows Media Center today)

[Big Booger]

http://www.pchell.com/support/limitedconnectivity.shtml

Did you check that page cashley?

[rtantti]

I didn't go through the entire thread to see if anyone else might have replied, but you might want to check your ethernet cables. I know this is a wireless system, but it is always good to make sure you have connectivity to the internet via a physical connection, before you unplug the connection and go wireless. There seems to be a little inconsistency with how some devices connect. The ethernet cable looks exactly the same as a regular ethernet cable, but it is a cross-over. Some systems want a cross-over from the modem (dsl or broadband) to the router, and then a standard ethernet to the computer, and visa/versa. Check your documentation. Unfortunately, many manufacturers don't get into that much detail. They'll just say plug the blue (but this doesn't mean all blue cables are crossover cables) cable into your computer, etc. So make sure that your cabling is correct first and also make sure it is directly from the modem (dsl or cable) that you're trying to connect. Once you are connected, configure your wireless and try from there. Good luck.

[Dehcbad25]

Just to add to the knowledge pool. Sometimes I see problems with NIC registering well in the DHCP from routers. I had problmes like this even in Cisco equiptment (thought it is a lot less common). So, one of the first things that I do is set the IP address manually, but then you have to be absolutely sure what are you doing.
I started wondering if now the routers manufacturers , or the Ip tables are being tweaked to reduce traffic by filtering, or reducing the priority of broadcast traffic, and hence the problem with getting an IP address. This sounds technical difficult, but believe me, I have seen it sooo many times. Last time it was with a brand new server that we installed 2 weeks ago. DHCP would not work, so, used static and it connected fine. Later after installing updates in the system, we put it in DHCP to try and it got successfully an IP address

[sarahog2001@hot]

Hi everyone,

Yes, I am another person with IP renewal problems. Have tried pretty much everything listed here. I'll explain what happened.

My friend wanted his wireless changed from 128bit encryption to 64bit. Which I successfully did (using the belkin settings 192.168.0.1 in explorer).

It was fine, all working.

I then went to put it back to 128bit. That is when the problems started. I set everything back as it was but now the IP address wont renew, even though it is set to automatic. So now it won't connect to the internet on 64 or 128. It just has limited or no connectivity all the time.

Feeling quite guilty, so if anyone has any suggestions id be grateful. Would it make sense to manually se the IP to something like 192.168.0.2?

Sarah

[Dehcbad25]

Yes, that actually would be the first thing to try. Copy the IP address from a computer that got the settings and then add some numbers, like 192.168.0.125
(if you have less than 25 PCs), Subnet mask 255.255.255.0, and gateway 192.168.0.1. For the DNS you will have to check the other PC. Some routers lately just give you the DNS from the ISP. Older used to redirect later, so your DNS would have been the router's IP.
I have seen it sometimes difficult to get an IP with the windows firewall on. Other thing you might want to try is to check the router status, and see if you can see your computer still there. It might not give you an IP, because it might think you already have one.

[hazar3000]

From a command prompt try "netsh winsock reset catalog" withoutthe quotation marks. After that might also try reinstalling TCP/IP again.

I try that and my ip address will work but only untill i turn my computer off, does anyone know why this happenes or how to fix it

[rockchicksdigme]

Ok, I have READ THE ENTIRE THREAD (wish everyone would before posting basic primitave fixes that were recommended at THE BEGINNING of the thread) and have tried everything here (I SUCCESSFULLY FIXED one of my puters though). I haven't found a soulution for the other puter yet (haven't swapped the nic yet) but will post it as soon as I do as I've found no other discussions yet (haven't really looked either)

ok now for the story...


I have 2 puters both running xp both using onboard lan both wired to the same router via known good cat5 cables to a cable modem connection.
Yesterday both were purring along (after I swapped the nic in "puter 2", I'll get to that...), I left for a few hours and came back to only one puter (puter 2) with access. Why only one would go is beyond me right now. I have Time Warner as provider and am going through AOL and NO I DON'T use ther crappy software just plain stripped down windows xp and use IE for my browser and set my security according to where I will be going hehe. Anyways puter 1 got installed by TimeW's tech the other day he only hooked up my G/F's Dell (puter 1 the one that now has the connection prob) and after he left I plugged my puter (puter 2) into my router and had no connection, it's been awhile since I was surfing with puter 2 so I figured a wipe was in order since I do alot of multimedia crunching (A/V production, puter 2 "Silvia" is really good at it ;-P) and it had been over a year since reformatting and I forgot if I was porn hunting when I was last surfing so after reformatting I was still unable to connect or renew ip problem. I DISABLED ONBOARD LAN AND INSTALLED A PCI NIC AND NOW I'M BLAZING (that fixed puter 2 real fast) well, some hours after I got puter 2 online puter 1 stopped but in the connection staus box I see throughput and bytes keep comming in, I have run adware and antivirus no cooties found. So I wen't ahead and installed SP2 on comp 1 (haven't put SP2 on comp 2 yet) no avail, unable to renew IP. Installed Microslop patch, ran ipfixer and tried to set ip manually no go. So next I'll swap the nic in puter 1 and see if that does it, it worked for puter 2! Peace

Summary:
1> tech successfully connects puter 1 no prob
2> no connection to 2nd computer when plugged into hub
3> reformatting didn't fix puter 2 but swapping nic did
4> after a few hours puter one mysteriously losses connection
5> will swap nic in puter 1 and see if that nails it.
6> Check out my KILLER band myspace.com/desolateband!
7> I'll be back

I had the same problems as described in this thread. I tried everything suggested and nothing worked. Finally I came across a post that referenced the DHCP client. This was my problem. The DHCP client service on my XP box was not started. After I started it my "renew ip address" problem went away. The DHCP client service is what requests a new IP address from the DHCP server. To start this service in XP:

Go to Control Panel
go to Administrative Tools
go to Component Services
go to Services(local)
Right Click on DHCP Client and select properties
Set startup type to automatic
Click okay and reboot

This problem started when I upgraded XP to service pack 2. Somehow the upgrade turned off the DHCP client.

Hope this helps. Tooke me 2 days to figure it out.

[Linedawg]

Try running this repair tool. I have seen this error alot at my work.

http://www.snapfiles.com/get/winsockxpfix.html

If it is this the problem is in the reg with the TCP configuration with windows.

[Nicole301]

you can find this information by doing an "ipconfig" in the dos prompt

[nikolus]

I have just recently joined this fourm, and i am having the same problem with everyone. I was virus scanning my computer, and it all of a sudden turned off:eek: . I turn on my computer and I canno't connect to my internet! I've tried renewing and re what'evering the ip adress, I went to see if the DNS was on and it is, and nothing is working! Should I go to a professional, or what?

I have a HP Desktop and its connected to a router

[Faledan]

This thread is old, but led me to my solution, by-and-by.... Hopefully might help someone else out in the future...

3 comp wireless, over Netgear stuffz. 3rd comp would connect to router, but nono on internet, and /ipconfig would not renew and would have that funky 169.xx address.

Solution that did it? Go to wireless props, and check (enable) "rate adaptive". Soon as I did that, ipconfig had a valid router addy (192.168.xx), and internet functioned.

Not sure what happened - I just bumbled on to the fix that worked for me. ;) Good luck with your own problem - hope this helps someone.

[rik]

Thanks for the input!

[spricks]

Hi All,
I'm new. Got the same problem. But have a different hunch on the problem.

Do any of you own a PSP? It's got wireless functionality also.

Previously my 3 Win XP PCs, together with my PSP can connect wirelessly to my router.

When my 3 PCs could not connect, I notice that my PSP also could not.

Note, PSP does not use XP.

Hence, as opposed to the suggestion of all the good gentlemen who posted possible solutions, I DON'T THINK THE PROBLEM IS CONFINED TO THE LOCAL PC. IT MAY BE THE ROUTER.

Sorry, I tried everthing on the router-side (check all the detailed functionalities, soft/hard restart), but no solution.

I just wanted to share a different angle of the problem. Maybe someone with router-config experience can help. I noticed this thread has been alive for nearly a year. :-)

[thackerblf]

I'm having similar problems as everything that I have read in these forums. I'm using mediacom and just trying to get started has given me grays already! It states "Your computer could not obtain a valid IP address from the server. This may be a problem with your cable connections, cable modem. or NIC. (code=70006)" It was an itegrated NIC so I got a new one. That didn't work either. Bear in mind that I just reinstalled Windows XP Pro. And it is a Dell Dimension 2400. Can someone please help me?

[Dehcbad25]

to the last 2 post, chech in your router to see what it says about the DHCP clients. Does your machine appears even thought it is not conected?
Also try giving an alternate configurations to the PCs that cannot connect, in the alternate configuration put the static ip in the range of the wireless router and use the correct DNS, and see if you can browse the web after that. Also, I did have problems sometimes getting an IP address for the first couple of times if I had the Windows firewall on, so for test I would disable the firewall and try to renew IP adress again.
This should give you a couple of options

[sz7854]

Internet Explorer via cable modem is coming up slowly on my Win98 computer and eventually gives me the "cannot find page" window. Here are the steps I've taken so far to remedy my problem:

- I ran McAfee and Spybot.
- When I ran Ad-ware, my computer froze and I had to reboot it. I then reran Ad-ware without any problems.
- I ran WinsockFix for Win98.

Nothing's worked. I checked my modem and ethernet card, which are fine. I've tried to release and renew my IP address, too, but can't get the address to renew at all. Also, when my computer sleeps for a bit and then I attempt to shut it down, it freezes, giving me a black screen with small white dots in rows. Other than IE, all other programs seem to be fine. I don't know if it's relevant, but a couple days before my internet connection went down, I had downloaded and run Spybot and Ad-ware. Any suggestions??? I'm at my wits end!

[Dehcbad25]

Windows 98 is out of support from Microsoft, so if there is any issue with the OS Microsoft will not release a fix, making it more vulberable to attacks. It probably would be better for you to install Linux in that PC.
I haven't used 98 in so long that I don 't remember if it has some type of safe mode. If it has try running adaware and mcafee in that more.
Also, write down your dns address. Do "ipconfig /all" at the command prompt (in windows 98 type command in the Start>run)
If the DNS that appeas is your router (for example 192.168.1.1), which will be the same as your gateway, then you need to connect to the router to get the dns address from the status page.
in the command promtp type ping xxx.xxx.xxx.xxx (replace the x with your IP address).
Sometimes it happens that the router has old dns addresses. You should get a response back from the dns. If you don't then the easiest way is to unplugg the power for the cable modem and router and then wait 30~55 seconds (or more if you want) Connect the cable modem first. Wait until the cable modem is completely online (it can take a couple of minutes) and then connect the router's power.
If you more computers in the house connected to the router and they can connect fine it is probably not the dns but it can't hurt to test.
You will have to refres IP address after this, either by running "ipconfig /release" and then "ipconfig /renew" or by restarting the PCs

[penge]

I know this is an old thread but hopefully somebody can help out with my problem.

I have a wireless broadband modem (two-way radio apparently) provided by my ISP Mynow. Problem is until recently it would connect to the net using a USBNIC network adapter with no problem. Now though windows starts looking for a network address even after I've connected the modem and I'm on the net. This search for another network ends up with it finding the default 169.254.0.0 IP or 192.168.1.0 sometimes. I've been told these IPs are ones that windows takes up when your PC has a problem connecting. But this usually happens when I've already connected through my USBNIC without a problem.

I'm using Zonealarm and in the zones settings I have my usbnic ip set there and then this other network that it sets itself when my pc finds it.

Is this a security compromise? I don't think it is a software issue or windows corruption because we've reset tcp/ip, winsock, changed hard drives, everything and it is still happening.

Just to clarify this is what is happening.
1) I plug in my wireless modem and windows will start looking for the network.
2) I connect using my usbnic by clicking on my isp's icon on the desktop.
3) Internet is connected and i'm on but pc is still searching for this network (acquiring network) in system tray.
4) after a while it finds the default ip or the 192 ip usually and zonealarm sets it in zones as a network so I have two networks in zonealarm zones settings.


In ipconfig the dhcp is not enabled for my ppp miniport. And the dhcp it is getting is either the 192 ip or the 169.

If this other IP is a default when your pc can't find its connection why is it happening even after I have an established link via usbnic with my wireless modem?

Excuse my ignorance of these things, but is it possible that the modem is finding another network in the area close by and connecting to it.
I don't have other PCs connected to my machine, and I'm not networking them up or anything like that.

The only way to stop it happening is to do an ipconfig release. But I shouldn't have to do this everytime I connect to the net. Something is obivously wrong.

This is what i get when i do a ipconfig/release

[rik]

192.168.xx.xx is the address assigned by your router or modem\router combo. That is a valid IP for internet access. 169.254.xx.xx is an "APIPA" address, an auto-config address that Windows assigns when it doesn't get one from somewhere else.

[penge]

So if I'm using a wireless broadband modem when I first turn it on it's normal for it to connect and give me the IP 192.168.xx.xx even though that's not my ISP's IP address?

I'm still not sure why it does this. I can see this when I do an ipconfig/all once I've turned on the modem.

After that, when I connect, my usbnic connects to my isp's ip address. But then I still have this other ip address, the 192 one in there as well. So when I do an ipconfig/all I can something like this:


Ethernet adapter Local Area Connection
