This is not an Asus problem. The original poster doesnt need to worry about looking through his manual or contacting Asus. Its a Vista problem. Why?
Because Im using a brand new Lenovo T500 and have the EXACT same problem. No idea how to fix
it. Ive been googling for suggestions which is how I found this thread.
Turn on computer.
No wireless connectivity.
Have windows diagnose problem.
Says, "Wireless capability has been turned off on this computer."
Ask it to turn capability back on.
Everything works fine.
You have to do it every single time you turn on or reboot the conmputer. Its beyond annoying and there should be some fix
out there somewhere.
(Yes, my computer has a wireless antena switch on the front of the keyboard. Yes it is turned on and stays turned on. This is not the problem either.)
