No wifi adapter found Broadcom BCM43162

Question

Ii just installed Ubuntu 22.04 as the only OS. My problem is that the wifi adapter doesn't work or Linux doesn't recognize it for whatever reason.

I'm using this code from another post:

wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info && chmod +x wireless-info &&& ./wireless-info

This is the information it gives me: https://pastebin.com/TvL3HNht
