I have just turned on my laptop and my wifi is not available! I cannot see my wifi settings and turn it On/Off Check this Screenshot and This Screenshot. I have installed my ubuntu alongside windows 10. First time that i used ubuntu my wifi did worked pretty well. Im using Ubuntu 20.04.2 LTS and my kernel version is Linux 5.8.0-48-generic, which is updated to the latest version. I did searched many times but can't find any solution for this problem.

I have collected some informations about my Wi-Fi by the following script and paste the output here:

  • You may want to go back to the 5.4 version kernel.

  • I have same due to updates. I conclude the Nvidia packages are related because some versions of kernel 5.8.0.xx won't launch X11. Suspect planning for Wayland is related. However, after clearing out Nvidia, I solved display problem but now wifi and TouchPad do not work. Wired ethereal OK. Intel Wifi 6 AX200 on Dell Precision 7200

  • Same problem but I'm not dual booting, just a pure Ubuntu 22.10 install.

Just registered to add up to this, so I can't upvote and/or comment, but the "Turn off fast startup" in Windows does the trick and needs to be set as the best answer, as the "power off by holding the power button" is really bad for the file system

To properly solve this issue you have to disable Windows fast startup:

Windows Control Panel

And when leaving Windows always do a shutdown because as you can see in the config "restart isn't affected".

As stated in the iwlwifi documentation:

About dual-boot with Windows and "fast-boot" enabled

If you have a dual-boot machine with a recent version of Windows and start seeing problems during initialization of the WiFi device when booting Linux, the problem could be due to the “fast startup” feature on Windows.

With this feature enabled, Windows don't really shut down the entire system, but leaves things partially running so you can start the machine faster again. Try to disable this option, on Windows 10 it should be in “Control Panel→Hardware and Sound→Power Options→System Settings”. Select “Chooose what the power buttons do” to access the System Settings from the Power Options. Then disable the “Fast Startup” option in “Shutdown Settings”. This will cause Windows to fully shutdown and may solve the issue.

  • Nothing can be left "partially running" when the the CPU and RAM have no power.

    This is the iwlwifi documentation, not mine. Don't shoot the messenger. Besides that, changing this config solves the problem anyway.

  • Windows fast startup was the problem! Solved right away! Anything else failed miserably! Just disable Windows Fast startup, after you find where they've hidden it! On Kubuntu 22.04 Dell XPS 13 9370 Jul 26, 2023 at 20:46

Solved my problem just by turning off my laptop by holding power button! because i have Ubuntu alongside Windows 10, I think both of them will affects each other and change some setting before Shutdown/Restart; Like some problems of headphone or this WiFi problem.

I hope this will help other friends.

It worked for me too, the turn off by pressing holdig the power button and in the grub menu choosed ubuntu. I could see that the description of the network changed from "Network Controler" to "Wireless Interface". Very weird solution.

Turn off the Windows and "fast-boot" is the key! When dual booting, windows 10 keeps the network card connected for faster boot up, which blocks use with ubuntu. Described in the following link - https://www.howtogeek.com/243901/the-pros-and-cons-of-windows-10s-fast-startup-mode/

I had the same problem, and in that case it was a partially successful upgrade process. Use the 'lsmod' command to see if the driver is actually loaded. If it is not, you may need to connect to the internet by other means and download the driver or use the installation media to add the driver back in. Alternatively, maybe you could boot in to an older kernel via the grub menu?

Hope that helps.

  • Please explain 'driver's? Kernel module?
    – pauljohn32
    Apr 22, 2021 at 13:23
  • This is the actual driver that is loaded in to the kernel. The easiest is probably if you can use a usb ethernet cable and plug in somewhere THEN use the "Additional Drivers" tool in Ubuntu to add what you need. It is an automatic process...

This was the solution to my issue! I have a Geekom Mini IT11 PC, with Ubuntu 22.04.3 LTS and Windows 11 on dual boot. Whenever I log into Windows and then log into Ubuntu, I run into the same issue as described above.

For the scenarios where Ubuntu is unable to connect to Wi-Fi, in journalctl, below logs are generated.

$> journalclt|grep iwlwifi

After disabling the setting in Windows discussed in the above solution, I power it down and then log in Ubuntu. Wifi connects fine now, and I get the below log in journalctl:

I also met a similar issue:

  • I couldn't see a list of WiFi to choose from (but I actually can use it, since I configured it during installation)
  • I couldn't use Bluetooth (the toggle on the UI won't work)

The first problem was solved by this solution, and the second was by running systemctl restart bluetooth.service
