Bug 1864188 is marked as a duplicate of this one.
I am not sure this is correct so I added my comment into 1864188.
To increase chances that somebody sees it, the comment says that, on my
system, the iwlwifi driver shipped with the standard bionic kernel
5.3.0-46 seems to be loading the wrong
This regression was introduced by stable update. That means all 5.3/5.4
kernels are affected(including all linux distributions that comes with
5.3/5.4 kernel).
There are 2 ways to fix this issue
1. Find the bad commit in stable update and revert it
2. Find the fixed commit from v5.6 and backport
Just diagnosed my fathers brand new System 76 laptop. Same issue. Just
got GRUB to boot 5.3.0-28 by default to get him up and running again.
Sometimes it's hard to be a Linux fan. Telling him "oh yeah, just wait
until 20.04" is unacceptable quality for Ubuntu.

For anyone googling, I can confirm that my Thinkpad X1 Yoga Gen4 with
intel AC 9560 wifi card has no wifi with 5.3.0-29+ but does work with
5.4.0-17
Thinkpad X1 Yoga Gen4 with intel AC 9560 wifi

Thanks for working on that bug but I have to say that this is
ridiculous. A kernel update gets pushed with a mayor regression that
breaks Wifi and it takes over one month to fix that. The fix for this
issue didnt even land for 19.10 so far. This is just bad.

Not sure if this is the right place, but I've had the no wifi problem on
my Asus Eee PC (Intel Atom) for both revisions since 5.3.0-28 generic

It claims the fix lands on v5.4.16 and v5.5, and this patch already has been
included in our focal kernel. It doesn't work for us.
