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?
Network adapters
and deselecting the optionAllow the computer to turn off the device to save power
(in thePower Management
tab). If there is aTransmit power
option (in theAdvanced
tab) then you may also want to try setting this to maximum.
