I believe the driver for this NIC should work out of the box (it does on other distros), but for some reason I can't for the life of me get it to work here.
I've already tried downloading the official driver from intel and copying to /lib/firmware and rebooting.
I've also tried doing
sudo apt install linux-modules-extra-5.11.0-27-generic
But it says I already have the newest version.
Finally, I've tried
sudo apt install --reinstall linux-generic
I see an error:
Error! The /var/lib/dkms/backport-iwlwifi/8324/5.4.0-81-generic/x86_64/dkms.conf for module backport-iwlwifi includes a BUILD_EXCLUSIVE directive which does not match this kernel/arch. This indicates that it should not be built."
I'm thinking this has something to do with my problem. But is this something I can fix, and if so, how?
