When I run ifconfig, wlan0 still shows up, but it has no IP address. The (gnome) panel ethernet icon is there, but the wireless icon is gone.

Then running iwconfig again, I get
donny@Maui:~$ sudo iwconfig wlan0 essid MaunaLoa commit
Error for wireless request "Commit changes" (8B00) :
SET failed on device wlan0 ; Operation not supported.
But still no wireless icon in the panel (and no net connectivity).

I should add that everything was working fine until I tried to set up a VirtualBox (Windows) VM and it had no connectivity. I mucked around like a stupid blind noob trying this and that which I found via this forum and Google. I never did get that to work, and now I've totally broken my wireless.
Please, please help.
