I believe the point of Karl's suggestion is to allow windows to enable
the wifi interface in the laptop, then to kill windows by powering
down without going through a normal shutdown, when windows may disable
it again.  Correct me if I am wrong Karl.

Apparently this has worked for some, including Karl. Others have
suggested hibernating windows.  Of course any time you kill windows
without a normal shutdowndown there is the risk of disk corruption.
Also if you use windows you will have to repeat the exercise.

It may be worth trying in order to determine whether this is the
underlying cause of your problem.
