WiFi went with the correct driver immediately on my Acer 5750G and makes a good impression. However, the sound was choppy playback via Bluetooth always what annoyed me. Then I read that even some computers Bluetooth is not recognized if PIN 51 is not masked, but it has been recognized with me yes. So propbeweise times the PIN taped with scotch and since Bluetooth also goes perfectly. I would have liked a guide for the PIN.
