The internet connection is, in fact working. Another wired desktop in the house is connecting just fine, as well as my wireless laptop. The router is a Netgear WGR614v6. The computer in question is connected to a basic linksys 4 port router, which connects to my ps3 just fine. If I run ipconfig /all on the desktop, It even identifies the custom dns servers I have specified in the router, and I can load the web interface for the router. I have tried the MS Fix-It which reinstalls the TCP/IP stack, as well as searching the services list for bonjour, or the other item that Apple apparently installs, and none were there.
Seeing how I can load the web interface in a browser, and identify, but not connect to other computers on the network, the network adapter seems to be working. Wondering if it's a driver issue, I even installed the newest Realtek GBE drivers from Gigabyte's web site.
Another interesting thing to note is that in the course of troubleshooting, I found that the port that my PC had been plugged into on the router had become bad. If any cable is inserted, regardless if plugged into a PC, the activity light for the WAN port blinks steady. The onboard activity light on the motherboard does not do this, so I can assume it is only the router. I moved the connector to the same port that my PS3 works on, to insure the router is not the problem. I also tried an older linksys gateway set to router mode, with the same result.
Any ideas how to go about resolving this?
FWIW here is a screenshot of my ipconfig. Maybe I'm missing something...
DNS Servers are not the custom ones i mentioned above because i set them to automatic.
