NetworkManager drops connections

Hi,

I'm using NetworkManager-0.3.4-1.1.0.fc3 on an FC3 laptop with b44 and ipw2100 
network devices, and its worked more or less OK for a while. However, I have 
just moved to a new network, and here I an having problems with the 
connection being dropped after periods on the order of an hour. I have the 
same problems with both the wired and wireless connections.

I've pasted below the messages for system logs, which show what was happening.
I'm not sure of this is a problem with NetworkManager, DHCP or something else. 
The network I am using is very well developed so I doubt the problems are on 
that side.... Any suggestions ?

cheers Chris
