Bose QC 45 not connecting to Windows 11. Worked in Windows 10. Only shows up as LE-Bose QC45 and says "Try connecting to your device again"

I'm trying to connect my Bose QuietComfort 45 but when I try to add new bluetooth device I get the error "Try connecting your device again." It also only shows up the LE Bose QC45 which is the lower quality connection for headsets rather than studio audio. There was one time it connected but showed as "other devices" and was a generic icon not a pair of headphones, I have not been able to make it connect again since.

The headphones work fine with my phone, and worked fine with my PC before upgrading to windows 11.

So far I have tried:

  1. Updating and reinstalling bluetooth drives

2) Updating Bose headphone drivers

  1. Enabling "Allow bluetooth devices to find this PC"
  2. Enabling and restarting Bluetooth Support Service and Bluetooth Handsfree Service
  3. Going to Device and Printers, adding a new device, selecting Bose QuietComfort 45
  4. Running the troubleshooter for both Bluetooth and Hardware and Devices

Nothing so far nothing has worked. Is there another solution that I've missed?

    Just an update for anyone experiencing similar issues:

    Turns out my Wifi router was too close to my PC and causing interference with the motherboards Bluetooth. I bought a USB Bluetooth adapter that was advertised as a bit more robust in terms of signal and turned off my motherboards built in Bluetooth. This has resolved the issue for me. Good luck!

    I have been fighting with my headphones for the past 2 years, ever since I got a new pc with built-in bluetooth. They worked just fine with an audio cord, but would only ever see LE-Bose as the only bluetooth source, and even then fail to connect. The headphones seemed to arbitrarily work sometimes, but never well. I resorted to getting a usb dongle, which didn't result in acceptable audio quality. Every few months I'd try again, going down rabbit holes of reinstalling drivers, installing 3rd party drivers, system updates, reinstalls, registry editing...all to no avail. Countless hours over the past 2 years, completely stumped. This comment right here was what sent me on the short path to finally figuring it out. It turns out in building my pc, I hadn't connected the antenna to the bluetooth adapter.

    What I was convinced was a bluetooth driver issue was actually a hardware issue, and I would not have been able to figure it out without this comment. It may not have been the same pair of headphones, or even the same problem, but I nonetheless wanted to go out of my way to make my first support forum post to say thank you. Thank you for putting an end to years of pain and heartache.

    Hi Carlo,

    I have followed all these steps and yet the issue still persists.

    Cheers.

    I had tried everything in this thread and other threads and could not find the issue until I just started hunting around the new settings menu and found a setting that got this to work.

    When I connected to my computer running Windows 10, my Bose QC II headphones would show up in the audio output device list as Headset (A2DP / Hands-free) and Headphones (Stereo) - they were separate, selectable and changeable devices. I use SoundSwitch to switch between audio devices quickly and would often switch between these options, depending on if I was in a virtual meeting or listening to music.

    For whatever reason, Windows 11 no longer separates these two modes into different devices - instead, you only get the Headset option by default. AD2P / Hands-free is not great for audio - it sounds like a phone call through a Bluetooth headset. You probably noticed that whenever sound did play, the microphone would turn on too - just like a Bluetooth headset.

    To change it to Stereo, I had to go to Settings > System > Sound, then scroll down to "Input" and select the arrow next to the "Headset". Above "Input Settings" is an option that says something along the lines of "use as default for voice". I selected something along the lines of "use as default for audio" and it fixed the problem instantly. This option is no longer listed on my machine, so I can't tell you exactly what it says, but it's pretty self explanatory. FYI - this section also shows you the difference in audio quality between A2DP and Stereo (1 channel 16 kHz vs. 2 channel 48 kHz).

    Update: I had the same issue pop-up again and the above options were no longer available. My workaround the second time was going to Settings > System > Sound > Headset, then turning Enhance Audio on or off and on.

    Okay here's most likely your solution to the problem. This board will come with an antenna and you may not have attached. Try attaching it and see if that resolves your issue as the radio for the BT is integrated with the wifi.
