I re-registered for the forum just to tell you:

YOU ARE A BOSS!!!

I can't tell you how many other BS posts I read elsewhere on the web about how to solve this issue and your solution does it in 2 simple commands. I was about to go out and buy a USB Wireless Adapter at Fry's tomorrow.

YOU ARE A BOSS!!!

THANK YOU.
