I've been having this problem for the past 3-4 weeks now. I had an old Zyxel router that my broadband provider had given me for free and thought the problem might have been with it. Today I got a new router, an ASUS DSL-N55U and the problem persists. My internet connection will disconnect (both cable and wireless for all devices) for seemingly no reason. Upon restarting the router, it will connect and be fine for a while until it happens again. Sometimes it stays online a few hours, other times a few minutes. It doesn't seem to be a specific application that disconnects it, as it disconnects when using many different applications and devices. (Although the old router did disconnect when refreshing game server lists, as it flooded the router. The new router doesn't seem to have this problem) It's been bugging me like crazy, any help/advice would be greatly appreciated! Thanks!
