Hello everyone, I have a problem that is driving me crazy. The integrated Bluetooth adapter of the wireless card atheros qualcomm Killer n1525 most of the times is not even detected by the laptop. In fact, in Device Manager is not even listed. Only a few times, and for no particular reason (at least that I can understand), bluetooth magically appears when I start the laptop, and then disappears again in the next boot. In one of those moments I tried various drivers, and those recommended by the manufacturer can operate perfectly bluetooth, that the few times is detected shows no malfunction. I tried several times to open the PC and remove/replace the wireless card, and each time the Bluetooth appears, but only temporarily. Further inform you that the wireless card works perfectly and I have never had problems. By clicking on "Show hidden devices" in "Device Manager" of course I can "see" the Bluetooth. Post some pictures of the properties of the device. I thought that the problem can be traced to a problem of conflict between devices but I tried to start the computer in Safe Mode or disconnect all USB devices without result, and frankly I would not want to format the pc just for that and I would not even change the wireless card, as with the Killer I am quite well. Tips? Thank You and sorry for my english. I’m italian These are the screenshots: http://oi58.tinypic.com/rtdksj.jpg The P650SE is flashed with the premamod bios version
