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 May 24 17:57:23 localhost NetworkManager: DHCP: Starting request loop, overall start_time = {1116953843s, 464466us} May 24 17:57:23 localhost NetworkManager: DHCP: Request sent, waiting for reply...
