2008 - What is killing my Internet?

I am having problems with something killing my internet connection. For some reason after about an hour or so, my connection goes dead and I have to restart Mandriva. If anyone can give me any advice on fixing this problem that would be great. Here are my specs,

AMD Athlon 6000+
M2N32SLI Wireless Motherboard w/ Realtek Wireless built-in.
Linksys WRT54GS router
Clearwire Internet

Mandriva 2008 - Current
Ktorrent w/ bandwidth limitations
Kopete
Internet connection w/ WEP enabled
Firefox

It seems that when I leave my computer and come back later when the screensaver has been running, is when it is dead. If I am sitting here using the machine, it does fine and I don't have any problems. When I come back and it is dead, if I go to "Manage Wireless Networks" and "Refresh", nothing comes up. Nothing. If you need more info, just ask, I will provide you with what I can. Thanks ahead of time,

Your problem is so tricky, anyway when it goes of what do u do to know that its eighter your Pc or Router, bcoz i would think of doing some pings to the router, or my own localhost, or every do traceroute, just to know where the problem is, either i personally think u don't loose the connection but it just freezes that u can do anything, the other thing that i have descovered is when u reboot, its like u are setting the system to this command "/etc/init.d/network restart" Maybe one last thing is try rebooting your router instead and see what happens, Others, u can make sure that your network manager is fine, or don't use it, for sometime and see what happens.

I know it won't FIX the problem, but it's a way of avoiding it, disable the screensaver

Thanks for the help guys. Before I left the house today, I turned shutdown Ktorrent, and when I got home, the connection was still up and running, so there lies my problem I believe.

Okay, I found out that as long as KTorrent is not running, my internet connection is always connected for extended amounts of time. I also have windows XP dual booted and when I run UTorrent it runs fine for days. So it is definitly a problem with KTorrent running for an extended amount of time. Any ideas on how to deal with KTorrent? I limited my connections to 50 total and ten per torrent but it is still a problem.

Try using a different Torrent program, I believe there are quiet a few available.
Enhanced CTorrent
qBittorrent official web page
TheGraveyard.org :: QTorrent - A Qt BitTorrent client
The libTorrent and rTorrent Project - Trac

Good Idea, I will try that.
