Ubuntu 22.04 Wifi not working sometimes - Dual Boot - Network Unclaimed

**luxolu** · May 27th, 2023

Hi guys,

First, I'm sorry i feel i needed to post this because i have tried many things to solve this but i couldn't yet.

To add some context, I'm using a laptop XPG Xenia 15. It has Dual Boot configured (at first it came with Windows 10 (never upgraded to 11) and i added a new partition for Ubuntu 20.04)

After some months, Ubuntu 22.04 got released so i upgraded it.

This is kind of weird because i usually use this laptop for work (ubuntu 22.04) and just sometimes i use Windows 10 in order to play some game with friends. Sometimes after I use windows, Ubuntu 22.04 starts having issues with the wifi (ethernet and usb tethering using my cellphone works well).

Many things i have fixed it by trying the following:

Reinstalling driver for my network device (wifi)
Reinstalling network-manager and restarting the service
Restarting the laptop many times

Just to let you know, using Windows 10, the wifi is always working well.

A bit of additional information is that i'm using Ubuntu 22.04 and the kernel is 5.19.0-42-generic and when i run this command:

Code:

lshw -C network

A fragment of the result is :

*-network UNCLAIMED

Please, help me.

Is Fast Boot an issue? https://wireless.wiki.kernel.org/en/...t-boot_enabled

Are there any clues in the message log?

Code:

sudo modprobe iwlwifi && sudo dmesg | grep iwl

Hi!

I tried disabling fast boot and it worked automatically!

Anyways i run the command you asked for:

[ 5.225183] iwlwifi 0000:3e:00.0: enabling device (0000 -> 0002)
[ 5.257353] iwlwifi 0000:3e:00.0: api flags index 2 larger than supported by driver

Not sure if that is relevant now that this is working correctly.

Thank you very much @chily555!
