Ok i have a wireless dsl adapter, since about two weeks ago, I'd try to connect a DoD1.6 server, it'd get to Precaching server info or w/e it is, it crashes, and says NET_sendpacket error: NO ERROR. (This also happens for about every steam game i have, but dod the most)
For Guild Wars, my internet disconnects sometimes when i go to different places.
I've tried changing the -heapsize for my programs, but that hasn't helped. I think i read something about turning off a NAT thing, but i don't know exactly what it is, and what it does, and how important it is.

Thanks if you find something helpful.

Aww, c'mon guys, did i post this in the wrong spot? I'm sure you guys can help me!
