It was working great for more than a year but now the "upstairs" computer is losing its connectivity. It is constantly losing its connection and disconnecting from the internet, which is very infuriating in the middle of a game.
At first, unplugging and replugging the modem and router were working but not anymore. Now it wont connect at all. The funny part is I still have an IP and DNS when i use ipconfig from the cmd prompt. When I ping or use tracert I get no reponse. The downstairs computer is working perfectly fine, which is allowing me to post this. (Which means the modem and router are still working fine!)
I've tried everything for the upstairs computer and I completely stumped. I tested the wires, but all the lights come on and respond appropriately. I've reset the router to its factory defaults and reinstalled my browser, Firefox, all to no avail. I've unplugged both and held the reset buttons. I've checked for viruses using AVG and spyware with SpybotS&D. I even tried taking the cable wire and connecting it directly to the computer but I still cant access the internet.
Please help! I'm completely stumped....
