I've successfully installed and run a fresh version of Ubuntu 20.04 for about a month without connectivity issues of wifi, bluethooth, etc.

Yesterday after installing Windows 10 on another partition on the same drive, Ubuntu no longer have a wifi adapter available.

I've tried several different solutions posted by others, here, here, etc. without luck. I've now completely erased the whole drive and reinstalled Ubuntu 20.04 from scratch but the problem remains, of course trying the same solutions again.

Running lshw -C network prompts:

...
*-network UNCLAIMED
    description: Network controller
    product: Wi-Fi 7 AX200
    vendor: Intel Corporation
...

After following this answer, running:

sudo apt-get update
sudo apt-get install linux-oem-osp1

The command dmesg | grep iwl prompts the following:

[   2.547276] iwlwifi 0000:28:00.0: enabling device (0000 -> 0002)
[   2.676918] iwlwifi: probe of 0000:28:00.0 failed with error -110

My motherboard is a MSI MEG Unify 570x. Wifi Module is enabled in BIOS.

Some suggest disabling fast-boot in windows, which is no longer an option, since it isn't installed anymore. Any suggestions what might cause this issue still?

    Did you follow this method? https://help.uaudio.com/hc/en-us/articles/213195423-How-To-Disable-Fast-Startup-in-Windows-10 Fast startup is certainly still a 'feature' of my fully updated Windows 10 laptop. https://i.postimg.cc/7LdWV0JQ/IMG-0618.jpg I suspect that fast startup is exactly the issue.

  • That's the problem, I erased my whole drive, so Windows 10 is no longer installed and therefore I cannot do this. Would it make sense to try to install it again, just so that I can disable this. I'm really out of ideas otherwise. – Void Feb 09 '21 at 21:46

    If you purge linux-oem-osp1 and reboot, is the dmesg | grep iwl the same; that is, probe failed -110? – chili555 Feb 09 '21 at 21:52
  • @chili555 yes, just tried and the exact same message is prompted. – Void Feb 09 '21 at 21:59

    Are those the only iwlwifi messages? Nothing about firmware? If you need to post a lengthy output, paste it here and give us the link: http://paste.ubuntu.com – chili555 Feb 09 '21 at 22:18
  • Here's a longer output from where WiFi is mentioned for the first time https://paste.ubuntu.com/p/5dQkwBVTpT/ – Void Feb 09 '21 at 22:42
  • Disable Windows Fast Startup feature. – Pilot6 Feb 10 '21 at 12:50
  • Windows is no longer available as I've wiped the ssd. Do I really need to reinstall windows to fix this? Is there no other way? – Void Feb 10 '21 at 15:41

The suggestion to disable the fast startup of the Windows 10 worked for me. The only question that is in my mind now is why and how did Windows hijack my wireless card? =)
