writing this review mainly to offer another one possible solution, where BT does not work.
Property me an Asus N56V bought and from the beginning was unhappy with the built-in Atheros wireless card.
After some searching I've decided for the Intel 6235.
Hardware replacement is without any problems, but then I came across the already repeatedly mentioned problem that
was not recognized despite the latest drivers the BT module from Win 7 system (but was hidden under system items listed).
Solution: Uninstall the "wireless concole 3" from Asus. Apparently, this console is for switching the WLAN + BT connection
over it slipped over the Win7 and hinders the function or the recognition of BT ...
Anyway, now runs both Waln and BT properly!
