Public bug reported:
After updating the kernel to the version 5.11.0.22 all network
peripherals stopped working. It appears they are not detected on lshw or
lsusb. I've tried with the ethernet port on the motherboard and an
external wifi board and also using USB tethering from a phone. None was
detected and network is not working. Then I've tried to go back to
kernel version 5.8 which is still working correctly. If you need more
info, feel free to ask me.
