    Intel dual band wireless-ac 8260 adapter issues

    HPEliteBook with Windows 7 using Intel dual band wireless-ac 8260 adapter keeps unistalling the adapter.

    Every time this happens I have to use system restore to go back to a point where it works. I have now disabled all Windows and HP updates to see if it still happens.

    How can I tell if it is the windows updates that is uninstalling the driver to the wireless adapter or if it is something else?

    This device cannot start. (Code 10). Intel dual band wireless-ac 8260

    For my system information, please see attached snippets/pngs.
    1. Dual band wireless-ac 8260 driver v.19.1.0 with Bluetooth driver v.19.0.1621 is not working, giving: This device cannot start. (Code 10).

    2. Also tried: Dual band wireless-ac 8260 driver v.19.0.1 with Bluetooth driver v.18.16.1 is not working, giving the same as in item 1: This device cannot start. (Code 10).

    3. Also tried inter-mixing the above drives; still is not working, giving: This device cannot start. (Code 10).

    4. Deleted/uninstalled the said drivers and let Windows 10 install the drivers - for ac 8260 driver v.18.40.0.12; for Bluetooth driver v.19.0.1621, everything is working fine. There might be a conflicting problem/s with the latest ac 8260 drivers.
    5. Last weird thing regarding item 4; If I "RESTART" my laptop; I also get not working: This device cannot start. (Code 10).
    6. But if I "SHUTDOWN AND START" then wait for about 20 seconds; everything is fine, the wi-fi/bluetooth works.

    Your respond/explanation/fix is highly appreciated.

    Intel® Dual Band Wireless-AC 7260

    Hi mo_63

    The best first step would be to go to the Sony website, then from there find the support page for your device, then download and install the device driver for that Intel Dual Band Wireless-AC 7260, then restart your device and then go to Settings - Update and
    Security - Troubleshoot to run the Bluetooth Troubleshooter . . .
