That solved the issue.

Either switch to the non-backports kernel or build a new module from Larry Finger's github site.

The Ubuntu kernels are fixed now but the twats haven't passed it upstream. As usual.

Sh*t, I forgot to mention. I'm on 5.4.0-0.

Unfortunately I've migrated to Beowulf on all my machines. Maybe someone else can tell. I assume yes, because before migration WiFi worked.

I found this but the referenced bug seems to apply to kernel >5.0. I presume you're using the 4.19 LTS branch with beowulf?

Just to be sure can we see

[SOLVED] Beowulf and Realtek rtl8822be wifi firmware issue

dummy@example.com (uther) — Mon, 17 Feb 2020 14:21:59 +0000

I've found an issue with Realtek 8822 WiFi card after upgrading to Beowulf. It seems like firmware changed location because in /lib/firmware are:

/lib/firmware/rtl_bt/rtl8822b_config.bin
/lib/firmware/rtl_bt/rtl8822b_fw.bin
/lib/firmware/rtl_bt/rtl8822cu_fw.bin
/lib/firmware/rtlwifi/rtl8822befw.bin

but /lib/firmware/rtw88 does not exist:

dmesg | grep 8822
