I have a Toshiba laptop and a while back I have posted that I fixed this issue, by taping up one of the pins(don't remember the pin #, but I know it's the last one on the far right, if you are facing the board with the components on top).
It's been working great ever since, but lately if I try to update the drivers, it seems like it's working great, but if my laptop enters in a power saver mode, the WiFi will not reconnect, no networks are detected and if I check it with the the troubleshooter, it reports some driver issue.
I did not pay attention what is going on with the Bluetooth, though.
