I have an older laptop, Acer e5-572. I have set up dual boot: Windows 10 and Ubuntu 22.04. I only use Ubuntu on the laptop. The internal wifi card worked fine since I set up Ubuntu, for ~4 months. Now, after a recent upgrade, the wifi does not work, wifi device is not shown. I'm not exactly sure what got updated, and how to do a rollback if possible.
If I launch Windows 10 on the same laptop, the internal wifi card is recognized and works, so I assume this is a Ubuntu driver issue. "wlx98ded008cba7" is an external card I am using temporarily.
In the settings, it says: No wi-fi adapter found.
I found a script for generating a report on wifi issues here: https://askubuntu.com/a/425205/40018
wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info &&
chmod +x wireless-info &&
./wireless-inf
This is the output of running the script, and posting a link because the content exceeds the 30k symbol limit: https://paste.ubuntu.com/p/XjR3cSh6QN/
I am also posting the output of running other commands I came across while trying to fix the issue.
How can I diagnose and fix this problem? I will provide any additional information needed, just ask.
Running nmcli --get-values GENERAL.DEVICE, GENERAL.TYPE device show shows this:
