What I've set up for my daughter, who's having a WiFi issue that seems 
to need some deep digging, is I'm cheating -- I made a script that 
removes and reloads (rmmod/modprobe) the appropriate WiFi modules, added 
the right /etc/sudoers stuff to make it not need a password, and put a 
link on her menu bar.  As a total-hack-don't-do-this-in-production 
work-around, it does the job.

P.S.  For all I know, there is a way to do what you want through Network 
Manager, but I'm not really NM-savvy, so...
