networkmanager drops connections

[Chris Jones <jonesc hep phy cam ac uk>]

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. Also, if I connect without using 
Networkmanager I don't have such problems.

Any suggestions ?

cheers Chris
