Network problem

[John Orford <John.Orford@Student.Uni-Magdeburg.DE>]

I hope it's ok to post this question here, I am a Linux/Debian beginner 
and I really have no idea where to go...

Anyway, after an hour or two of being online I get cut off (it seems to 
be fairly random) - after rebooting all is ok again.  So I guess it's a 
Software problem.

I have a lan connection, the network guy said that the network was ok.

I never had any problems when I had the usual KDE2, 2.2 kernel debian 
installation.  I generally only run mozilla over the net, sometimes 
Konquerer, SSH and RealPlayer.

I use a tulip module for my netgear card.

This is really killing me - cos I don't where to begin looking for the 
solution.

Help, would be appreciated.

John.
