    @chili555

    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.


    p.s. thanks to Josh the OP of the thread for starting it
