I just built this new computer. When I try to play Medal of Honor online, I constantly lose connection to the server. I get that green box at the bottom-middle of the screen and I cant move. Yet, I can see people move around and see the death messages pop up, and I can even talk. As far as I know, I dont lose connection to the internet (I'm on cable, btw). I know its not the ISP or anything to deal with my modem/router setup because my previous system works fine on the same network. I also know its not the integrated ethernet port I use on my motherboard because I tried a separate NIC, which gave me the same problems. I've downloaded almost every update/patch/driver out there for my setup, all of which didnt fix anything. I've uninstalled and installed the game 3 times already, so that isnt it either.

Epox 8RDA+
Anthlon 2400+
Corsair XMS 512mb
WD 80gb Special Edition
Radeon 9500

That's my setup. What could cause my losing connection to the server?
