firmware question during install + no wifi

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

Info like your first comment needs to be added into the body of the question with edit. Not as a comment.

Where the heck are you reading this?? That is not the README at the HRex39 git repo in the link I gave.

The Hrex39 repo is archived, read only and asks to use a different repo, which is https://github.com/lwfinger/rtw89 which has the admonishment. Are you suggesting that I use an "obsolete" repo anyways?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
