Router dies after 24 hours

I just don't get it. These routers are just driving me insane! I'm on my third router in less than two years and I'm having the same exact problems with this one that I had with the other two.

Current Router: Belkin F5D8235-4 v3
Past Routers: Linksys 350N
Linksys wrt54g (i think)

The Belkin is better about it than the two Linksys routers were but it is still annoying. I keep losing internet connection everyday if I do not restart the router. The whole router freezes up, wireless it gone, no internet, no home network so I can't even connect to the router setup page. I've surveyed the area with Insider when this happens and my wireless network indeed doesn't show up at all.

If I restart the router before it screws up, it will work fine until the next day. Sometimes one computer plugged into the router can access the internet while the other can't. You can tell when it is about to fail cause the internet gets noticeably slower.

This has to be some other problem that is causing this. I can't believe that I just happened to get three routers all with the same flaw. This has to be some kind of power problem with the wall outlets maybe or something else, but I have no idea about how to identify it or how to fix it.
