It seems there are some bug reports for the firmware for the AC-9462
chip. But none of the solutions works for me. My 19.10 ubuntu is fully
patched. My kernel is
Linux nb004 5.3.0-40-generic #32-Ubuntu SMP Fri Jan 31 20:24:34 UTC 2020
x86_64 x86_64 x86_64 GNU/Linux
Does it already load the lastet firmware (-48)? How can I check?
Do I need to install a new kernel?
I also installed the backport-iwlwifi-dkms, but I think there is no
driver for my card included in that package.
