Unreliable Wireless connection on 11.10
My wireless connection intermittently fails to connect to my network after booting. It repeatedly asks for the passkey, but entering the correct key does not work. Only a reboot cures the problem.
Here is the network report of my Lenovo 3000 N200 0769-B4G:

Many thanks,
