I'm posting for a friend who's internet is a little bit borked. He can't check his email so he wasn't able to register on this forum. He asked me to post this:
I have a Netgear CG814WG cable modem connected directly to my pc via ethernet, provided by Comcast, my ISP, on WinXP SP2.
The other day I downloaded and installed 2 updated drivers for my Nvidia fx5200xt and my Creative SB Audigy cards. I go about and reboot my machine after installation. When I log back into windows, I find that I cant get any pages to load with Firefox, I conducted a test to see if my internet was still working. Internet Explorer, mIRC, and Ventrilo still connect, though I cant check my email or upload anything with IE. Nor can I connect to Steam, or any game that uses Gamespy's multiplayer stuff, for instance, I loaded up Rome:TW and when I tried to connect to the lobby, the game crashed on me, and so does anything else gamespy affiliated. And I cant even direct IP in civilization 4.
I disable my firewall, antivirus or any sort of program possibly running and try it all again with no success. I tried ending every process running that I could, and still nothing. I then tried rolling back my drivers...still nothing. Even when i set my router to DMZ, I get no change in the situation. I've scanned and cleared any spyware or viruses on my pc. I've rebooted I don't know how many times following all these steps, and when trying to contact my ISP today, the phones are down due to a storm.
I'm fairly clueless about network connections and such, and would appreciate any sort of help available.
