If your equipment is the 2Wire HomePortal
Plug in the HomePortal, connecting your computer directly to the Ethernet jack.
Start a web browser and enter either "172.16.0.1/setup/cdless.html" or "homeportal/setup/cdless.html". If you get a web page you're doing great, skip to step 4.
You need to set up a local area network. If using Windows, go to "Settings->Network and Dialup Connections", then make a "Dial up" connection to the Internet via a "LAN". Skip the automatic proxy configuration, skip the email step.
You need to enter a "keycode" into the Home Portal. A list of keycodes can be found at www.2Wire.com/keycode
. For SBC Yahoo! DSL enter "522p 22p4 6262 22at f2nv".
Enter temporary login information. For SBC Yahoo DSL use a login name of "firstname.lastname@example.org" with password "sbcyahooreg". Your DSL connection should now spring to life.
Now you need to register and get a permanent password. Visit "support.sbcglobal.net/register", and enter your personal information (usually your DSL telephone number). Mozilla and Linux users note that you might have trouble entering your phone number, due to bugs in the SBC web page. Try a different browser.
That's it. You should be live. Run a speed test over at www.BroadbandReports.com/
to be sure you're getting all the speed you paid for.
If you have trouble, you can visit the secret management page on the 2Wire Portal -- "homeportal/management". Your HomePortal takes care of everything: it is an all-in-one box that functions as a DSL Modem, broadband router, firewall and home networking hub with WiFi, USB, PhoneLine and Ethernet, . Some of that functionality is hidden in the management pages (for example, the control that lets you lower the transmit power for 802.11b wireless WiFi networking). Note that the 2Wire registers itself, transmitting certain personal data (such as how many connected computers you have) directly to SBC and 2Wire. SBC and 2Wire can dial into your router for tech support. Big brother? Maybe. But also useful.
