Every few kernel versions it stops working and you have to find fixed
code and download and compile it to get it working again. Then a few
kernels later it happens again. When it worked it worked better that
the original card in the laptop, but it was time consuming to fixed it
every few kernel updates.
Your best bet is to simply replace the wifi card on the laptop with
one of the newer ones (that is what I did). Depending on your laptop
that should be possible. I replaced mine with an intel ax200 card and
it has just worked since I replaced it. You may have to read the
reviews on the cards to determine if others have used the card in a
laptop like yours. There are gray market cards on amazon for around
$22. My laptop is a 2016 model. You will have to do some research
to figure out if a ax200 or newer will plug into your laptop.
5GHz requires more attention to things like radio frequency interference RFI),
e.g., better shielding and changes to routing of cables . If the laptop was never
sold with 5ghz internal wifi, there could be issues such as radio frequency
interference affecting other subsystems. You might be able to look for changes
in teardown images to the antenna system if a newer version of the same model
is offered with internal 5GHz wifi.
