After updating my Ubunut 20.04, my wifi driver is no longer detected. Previously, this was an issue upon initial install and subsequent updates, but sudo rm /lib/firmware/iwlwifi-ty-a0-gf-a0.pnvm provided an instant fix as described here: Ubuntu 20.04 with kernel 5.11.0-40-generic does not recognize intel wi-fi 6E ax210 160mhz. However, it appears that this file no longer exists, so this fix no longer works. Reinstalling the driver also seems to have not helped.

Edit: See here https://pastebin.ubuntu.com/p/Gchqxh7rQ8/ for the output based on this post: My wireless/WiFi connection does not work. What information is needed to diagnose the issue?. Interestingly, upon running sudo apt update, the faulty file mentioned above reappeared, but removing it did not resolve anything.

This took over a month, but I've finally found a solution. The fix sudo rm /lib/firmware/iwlwifi-ty-a0-gf-a0.pnvm outlined in the above linked post only works for the version iwlwifi-ty-a0-gf-a0-59 of the firmware and not any newer version, i.e. installing the files associated with version 59 from here and deleting all others is what worked for me.
