I installed this module on 5.18.0-kali5-amd64 using ./install.sh but it doesn't load (only the wired adapter shows up). Here is my installation log:

$ sudo ./install.sh

This did it for me originally, run with sudo: https://askubuntu.com/a/1404795

However, the issue arose once again for me, and a different fix is needed this time so I am all ears as well.

Try ignoring it as well. My install ended up going through smoothly despite the warning. Possibly relevant source: https://access.redhat.com/discussions/6970514
