Ubuntu 18.04: Intel(R) Wireless-AC 9560 [8086:02f0] subsystem [8086:0034] Wifi adapter not detected after kernel update

[Kostas Giannakos]

"lsb_release -rd" output:
  Description: Ubuntu 18.04.4 LTS
  Release: 18.04

So, my linux kernel was updated to 5.3.0-40 today, and my wifi adapter is no longer functional. When I run "lshw", the usb-1 device is detected, but is "UNCLAIMED".
Booting with the previous kernel works, so I figured it's a kernel problem.

Hello,
same problem for me
Kernel 5.3.0.40 Ubuntu 19.10 WiFi not working
Kernel 5.3.0.28 and before, no problem at all.

Maybe this could be useful...

[Jeremy Soller (jackpot51)]

I have attached a patch for kernel 5.3.0-42.34 that should solve this issue.

[Ruben Vazquez (r.vazquez)]

I'm having the same issue. I've tried loading older kernels. Kernel 4.20-17 doesn't work. It renders the machine basically unusable.

[You-Sheng Yang (vicamo)]

@Kostas, we need you to follow #2 to collect debug logs so that further investigation would be possible. You may need to find some USB ether dongle or so to establish a valid network connection before being able to submit the report in regard to that broken WiFi interface.

For others, please file new bugs if you're not sure they're confirmed identical.

Should be a duplicate of bug 1865962, which was currently only fixed in 5.4.0-18 or newer in Focal. Is it possible for you to try Focal kernel?

  $ echo deb http://archive.ubuntu.com/ubuntu/ focal | \
      sudo tee /etc/apt/sources.list.d/focal.list
  $ sudo apt update && sudo apt install linux-modules-extra-5.4.0-21-generic/focal

[Johon Doee (jodoee11)]

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. This is just bad.
