Public bug reported:
Since upgrading from karmic to lucid I'm having problems with my wifi
connection. I'm using a laptop with an intel 3945. It connects without
problems to open as wpa or wep2 secured networks but loses connection
after some time. In most cases this will happen when transfering data
like downloading files or streaming media. Sometimtes I can reconnect
via network-manager, sometimes I have to unload and load the kernel
module (iwl3945) before it will reconnect to the network. The problem
occurs with the current kernel 2.6.32-22-generic as well as with the two
older versions 2.6.32-21-generic and 2.6.32-20-generic.
