If I disconnect from my WiFi connection, my laptop freezes. I'm still able to move the mouse, but my laptop won't respond to any input until I hard shutdown. Here is the output from the Wireless Info Script:

It also freezes if I try connect to a new network I haven't previously connected to unless I enter the WiFi password before it can freeze. I thought it may have been due to wireless power management, so I disabled that, but I still have the problem.

Thanks for your help!
