I have an XP partition, OpenSUSE, DreamLinux, Kubuntu and Ubuntu Studio partitions.

The Studio is the newest install and is the only one with this problem.

After a seemingly random period of time between about 10 minutes and 90 minutes my internet access (actually access to my router) just stops.

I have a wired connection.

ifconfig shows that eth0 is still as it was when all was working but if I try to connect to my router it tells me that it isn't there.

If I ifdown eth0 it comes down but if I then ifup eth0 it shows the right mac for listening and sending then it shows a fallback to loop and then it just does endless DHCPDISCOVER with varying intervals.

Can anyone give me a hint as to what might be going on?

I am sure of the harware since all other distros and XP have no problems at all. Also, my wife's laptop on a wireless connect to the router is fine.

If a screenshot or configs is needed let me know.

Thanks in advance,
Simon

Maybe check 'dmesg' and /var/log/messages. Examine installed kernel modules on the Ubuntu Studio and other linux version. I guess you have differnet kernel versions on each. Try to install a customized kernel on Ubuntu Studio.

I tried installing KDE (the default was GNOME).

I rebooted, logged in to KDE and all problems disappeared. The problem is certainly with GNOME.

I should have known better, actually. This sort of thing has happened to me with two other distros... I install with GNOME, strange things don't work or are random, install KDE, switch sessions, problems gone.

I am at the point where, if a distro defaults to GNOME, I will just install KDE, before I even touch anything.

Don't like GNOME anymore. Looks nice but is too flakey for me.

Thanks,
Simon
