Network Help - Frustrating disconnection problem... posted in the Web & Networking forums; It happened at another house also~
I'm hoping it's not burnt out or something, because it was fine for a long time after I bought it....
Unfortunately, yes, it is probably the card. Luckily they aren't too expensive. Post back and let us know what you end up getting, and that it really does solve the problem. If not, you can return it, and we can try to come up with something else.
