I have a linksys router (wrt54gsv4), and haven't really had any problems with it until now. I am not sure if this is a router problem or a problem with my computer but for the past week or so my internet connection keeps getting disconnected, the internet will work just fine for a few hours, but after that I get disconnected and I am not really sure why. I bought a new network card to see if that was the source of the problem, but same thing, after a few hours the connection died. I don't know if this is enough info for you network gurus to assess the problem, so let me know what else is needed and I will post it when I am able to.
