What the gehenna does the above mean?  

Some identified wifi gizmo _died_?  What does 'died' mean in this
context?  What does 'electronic shriek' mean?  And what does the 'maybe'
signify in this context?  i.e., are you saying something happened, or
_not_ saying it happened?  Saying _maybe_ something happened tells your
readers nothing.

Whatever 'died' means, do you mean that you subsequently got and
installed a new one?  What's the new one?

Is the new one perhaps an Intel Wireless-AC model 9260-series
wireless/Bluetooth card in M.2 2230 physical format, one like this (as
suggested by your dmesg output)?

My point is, you haven't even told us what the wireless hardware in
question _is_ (make and model), let alone why it should be surprising to
have a lack of functionality if something 'died'.


Maybe you should back up and start over, because the entire anecdote
starts out hopelessly confused.  Include a coherent account of what you
mean when you say that your gizmo 'died', please.

And, when you do that, you should consider writing a Subjet header more
descriptive than 'tahnks for the help'.

But you don't bother saying what the exact symptom is, or what you've so
far done to investigate,  except:


> When I use the settings feature for wifi,

> Make sure you have a wifi adapter plugged and turned on"

Speaking for myself, I have absolutely no idea what you mean when you
say 'the settings feature for wifi', but I'm guessing that you're making
a vague reference to some GNOME DE thing (that gives nearly totally
useless problem feedback).

You should run iwconfig -- to see what interfaces are valid.



Just running through marginally relevant suggestions you find on
https://ubuntuforums.org/ is a poor substitute for diagnosis and
testing.


What wouldn't hurt is removing and then reloading the iwlwifi module:

$ sudo modprobe -r iwlwifi
$ sudo modprobe iwlwifi
