user logout kills wlan connection
I am having a strange problem. I have a wireless lan in my home. Machine A is doing masqurading for machine B over a wireless lan. Using lynksys WMP55AG pci cards. Everything works fine, except, if a user logs into machine B, and subsequently logs out, the connection will die. ifup ath0 does not bring back the connection. Something in the process of logging out of kde, kills the connection and it can not be restarted except by rebooting.
I don't expect a solution, but can anyone suggest where to start looking to fix this?
