    My laptop is Acer Swift SF314-43 running Windows 11 Home, version 21H2.I'm not entirely sure what's causing my issue, but often not always when I'm turning my laptop on or resuming from sleep, my Bluetooth driver seems to fail, as shown below:Though usually when I restart, the issue seems to resolve itself until the next time it fails again.Additionally, I have run the Bluetooth troubleshooter in Settings a few times, in which it advises me to 'Reinstall MediaTek Bluetooth MT7921'. Upon doing so, said troubleshooter advises me that it has reinstalled the driver, however a refresh on Event

    Bluetooth in windows 10

    My computer specs are as listed in the profile. I think all of you guys are correct. I don't have built-in Bluetooth in mobo.

    I contacted skull candy headphones and thy have told me if I do not have built-in Bluetooth, I would need a dongle which supports at least a2dp. I do not know what the heck that means. I have a feeling I would need more than a cheap dongle.

    Anyone suggest some a2dp adapters. I searched but don't know what a2dp is so couldn't make a decision

    Windows Updates breaks bluetooth

    So Bluetooth stopped working (mouse etc) today.

    - Event Log says "The local Bluetooth adapter has failed in an undetermined manner and will not be used. The driver has been unloaded."

    -Device Manager lists Intel Wireless Bluetooth Device Status as "The local Bluetooth adapter has failed in an undetermined manner and will not be used. The driver has been unloaded."

    On a whim I checked the version number compared to what I had originally installed and sure enough the version is much more recent.... meaning one of the cumulative Windows Updates installed a newer... and broken!.... version.

    GOD, I CANNOT STAND WINDOWS 10.
