There are reports in the wild stating that firmware version 22.40.0.2 (included upstream in linux-firmware 20210315) for Intel AX210 caused some regressions. Downgrading to firmware version 22.30.0.4 (included upstream in linux-firmware 20210208) seems to have fixed those regressions for the people affected by them. Could you check if installing firmware_iwlwifi 20210208-4 [1] fixes your issue? > Best regards. > Philippe Cheers, Vincent [1] https://snapshot.debian.org/archive/debian/20210313T203823Z/pool/non-free/f/firmware-nonfree/firmware-iwlwifi_20210208-4_all.deb
