When installing ubuntu 22.04 LTS on a low-end Lenovo, it asked me about installing third-party firmware/software for wifi etc. I of course said yes, and entered in a password for secureboot where prompted. When I rebooted I was met with a blue screen detailing MOK stuff which I muddled through (I was not expecting it and I don't know if I did the right thing I stepped through the middle option).
Next when I booted into the OS for the first time it does not recognize my wifi card. There are no familiar options to join a network and nmcli dev ... only lists the lo device.
I feel that these two things must be related somehow.
Diagnostics:
sudo lsmod | grep wi
and
sudo dmesg | grep iwl
reveals no results. Other diagnostics:
$ mokutil --sb
SecureBoot enabled
$ lspci -nnk | grep -iA3 net
