I am using a laptop (Toshiba Satellite L755) with an inbuilt wifi chip (Atheros ar9002wb-1ng) with Win7.
For some reasons wifi is not automatically enabled on startup, i.e. the wifi adapter doesn't see any networks, although the icon says it's active. I always have to manually switch it off and on again using hardware buttons. Once I have done that, windows lists me available wifi networks and I can connect.
I updated windows and installed the latest wifi driver from the Toshiba web page, but the problem remains..
What do I have to configure to be automatically connected on system startup?
