hmm, it was "off" in the settings. So I tried turning it on and connecting to my bluetooth speaker to see what would happen, and the dmesg output looks like a mess (attached). The interface says the device is connected but it doesn't show up in pavucontrol. I'll try version 50 of the driver

So AX200 loads firmware iwlwifi-cc-a0-*.ucode, and that is currently of rev 48 from commit 40e4162adfc9 ("iwlwifi: update FWs to core45-152 release") in Bionic/Eoan/Focal and korg/master HEAD. Updating fw from these places won't help. However, could you test rev 50 from iwlwifi /linux-firmware[1]?

Hey, Followed your steps and still seeing the problem, but in case this is a clue: My wifi seemed to be working normally at first. After about two minutes of ping acting normally and browsing I tried doing `sudo service network-manager restart` to see if the problem came back and it indeed

It seems you're suffering from wifi firmware crash and the hardware is resetting itself occasionally. Please try: 1. backup your /lib/firmware 2. Clone https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/ to replace /lib/firmware 3. Shutdown completely for a minute and
