Hey there!!
As the subject suggests, this combo [BlueTooth - Acer - Qualcomm
Atheros] is my problem.
But before going any further I'd like to leave clear that I am
not, by any means, a Linux Power User [LPU], I just installed
Debian 11 in my laptop and are now discovering the pros and cons
of this OS, that's it!
After installing Debian 11 from an USB, I found out that the
blue-tooth wasn't working, so searching the net I found this web
pages that attempt to fix the issue, among them are :
https://wiki.debian.org/BluetoothUser/a2dp
https://wiki.debian.org/SourcesList
https://www.reddit.com/r/linuxquestions/comments/meaxi5/bluetooth_not_working_in_debian_11/
https://wiki.debian.org/BluetoothUser/a2dp#Pre-configuration
https://wiki.debian.org/PipeWire#Installation
https://unix.stackexchange.com/questions/559134/bluetooth-adapter-not-found-in-debian-buster/559147#559147
and many more that are not worth mentioning.
I've learned that PulseAdio was not doing the trick in my laptop,
so I tried PipeWire, but to no avail. Later I went deeper and
installed the Qualcomm driver, since my Acer Aspire E5-771G has a
'Qualcomm Atheros AR956x Wireless Network Adapter' as suggested by
-
https://www.systranbox.com/how-to-install-atheros-wireless-driver-linux/
-. The result was catastrophic! Not only the blue-tooth did not
work, but the WiFi was extremely slow.
Now I am open to anyone's suggestions to get the blue-tooth to
work, it worked under MS, therefore, I know the hardware if
functional
I have tried :
sudo iwconfig
lo no wireless extensions.
enp4s0 no wireless extensions.
