Network connection dropping

[marcboy]

I have a rather annoying little problem. I've recently made a switch from Ubuntu to Kubuntu after i needed to do a full system re-install. Everything was set up fine, fully updated etc. But i have noticed my network fails after time. All that is running is kTorrent (may be the problem). The connection is set up with a static IP and works fine at boot, it just seems to fail after an unknown period of time.
Im not at that computer at the moment so if theres any logs etc. you wanna see let me know and i'll get them posted.

If this were my machine, first of all, I'd fire the "Network Manager", not least to eliminate a potential source of trouble ...

You should, however, tell us about the type of network as well as the interface you're using (make and model etc. pp.).

Re: Network connection dropping

It seems to be kTorrent thats causing the network to fail. I may know the solution. i'll give more details if i fail to solve the problem

Re: Network connection dropping

Ok i still think its kTorrent but haven't been able to solve the problem. I thought it may be to do with my number of connections set too high. Put them down to around 40-50 and its still happening. Any suggestions anyone?

Re: Network connection dropping

I've had this problem with rt2500 pci cards and all distros except gentoo. I never found a fix, but running:

ifconfig <network_interface> down
rmmod <network_card_driver>
modprobe <network_card_driver>

and then connecting to the wireless network solved the problem at least temporarily. There's also a recent thread on the lkml about network cards dying after a random amount of time that might be related:

Re: Network connection dropping

This is now happening without kTorrent running so it seems to be a kubuntu issue. I didn't have this problem when i was running ubuntu its only been since the switch.

I checked out that link you gave but it made no sense to me. Oh and its not a wireless connection if that makes a diff.
