I am not all that new to Ubuntu (have been using it for 20 years now), but as all good friends, sometimes it still manages to surprise me.
After fresh install (Ubuntu 21.10 in an Asus ROG laptop) I cannot seem to get the wifi to work. I do not see a wifi icon and in settings-> wifi I get the wifi adapter not found error.
I am not an expert in Ubuntu (just a long term user) and I realize I know very little about how the wifi works.
As far as I can tell, the system is unable to find the wifi controller (I believe there isn't one).
I happen to know that the wifi controller does exist and works because this computer came with a preinstalled windows (not there anymore) with which I could use the wifi without problems. At this moment I am connected via wired connection which also works fine.
Any help would be very welcome.
I run the wifi diagnostic script that I found in the forum with the following results.
