BT coexistence not working on 2,4 Ghz Wifi #348

Open Feuerhamster opened 1 week ago

Feuerhamster commented 1 week ago

Wireless card: RTL8852BE Tried on Debian 12 (Testing), Pop OS and Fedora Workstation 40

I have a very strange issue with coexisting Bluetooth audio and Wi-Fi connection. After a few seconds, the audio on the Bluetooth headphones stutters. After about 2 minutes, there is no internet connection anymore. It says Wi-Fi is still connected, but no traffic gets through.

This issue only appears if I am on a 2,4 Ghz Wi-Fi Network. Some people in forums suggests to just use 5 Ghz Wi-Fi but except for my home, I cannot control what frequencies are provided in, for example, public networks.

It's really annoying because the basic use case of watching YouTube on the train is completely broken.

I tried to install the driver manually from this repo, but that didn't help and since it is now included in the kernel, I guess it wouldn't change anything.

Is there something I can do to get BT coex working on 2,4 Ghz Wi-Fi networks?

hello, @Feuerhamster. this is actually a backport repo you would want to use this only if you have older kernel version that is not supporting your needs for your wireless driver.

I would debian testing's in-tree driver for rtw89 would support 8852BE properly.

Here are some examples for giving me good debug output to see what you are working with.

You can just adjust commands below to for rtw89 specific modules/names/files:

I know that the driver is included in more recent kernels. On the distros I've tried I used a clean install with the included driver and did not installed this repo on top. But I didn't know where else to ask for help for this issue.

I currently swapped my wifi card so for everyday use, but I will post the debug logs here as soon as I swapped back for debugging.
