Just installed xp media center, couple of problems

[jyeh3112]

I got a new computer, and i installed xp media center on it. I am getting some problems, and i'm not sure if they have to do with xp media center, or my hardware, or my software, or what. Thanks in advance for the help!

Problem 1: Wired connection speed incredibly slow. When i connect to the net through my NIC, it basically doesn't work. ITs super slow, transfers at like 2k/sec and i'm on cable. my roomates computers are fine and when i plug in my cable into their computers it works fine, so i know its something wrong with my software/hardware. When i change my connection setting to 10mbit/sec HALF DUPLEX, it gets a lot better. However, my downloads still go about half as slow as my friends. If i change to any full duplex setting or 100mbit/sec half duplex, its rediculously slow. So right now, i am using my wireless card.

Problem 2: I can't download java vm onto my computer. When i try to go to the download page, it brings me to the "cannot find server" page in IE 6 and when i use firefox it says "document contains no data". I've tried on my roomates comp and they have no problems. When i search through google and go directly into the download page, it says i can't download because
" We encountered an issue while trying to automatically install Java™ software onto your machine. As a result, Java software was not installed properly."

thats about it for now, i had some random problems with my windows services not automatically starting on boot up, but i reinstalled windows and fixed that. sigh, it hurts to see my new computer dying. thanks for the help!!!

[edit] some more info on my connection. it seems i just can't get into certain sites sometimes, like i cna't get into espn.com right now using any connection (wireless, 10mbithalf) nothing works. roomates have no problems
