But first, the tiresome subject "not operating Bluetooth", as it was noted by some Vorrezensenten repeatedly.
Short and sweet: Bluetooth works, see the uploaded product images.
I do not know if there might not be some people consciously, but: The Bluetooth feature must in most laptops initially with a shortcut key (this varies depending on the model, the best the manual consult) at the hardware level to be activated in order for the operating system the Bluetooth chip detects at all. In a WiFi / BT Adapter replacement must be made even necessarily because in this process both the WLAN and the Bluetooth after removing the old adapter is first turned off automatically by the operating system - at least that was the case with me.
After you have installed the new adapter, and the two antennas properly connected the Centrino is 6235 by the operating system (Windows 8 x64 Enterprise with me) also recognized correctly unless you have the features WLAN & BT via the keyboard also activated. Of course advisable at this point to install the latest driver from Intel site.
On the whole I am satisfied with the product. A star deduction is available for occasional - really rare - disconnections that not occurred in my old Centrino 1030. Since I used to but still under Windows 7, I put the cause first on the Kombi "new operating system + not quite mature driver" ;-)
