ubuntu 22.04 / Mediatek mt7921e network card "No wifi adapter found"

Question

I have just installed ubuntu 20.04 (alone, no dual boot) on a hp elitebook laptop (which is new). Wifi worked for a few hours, but then stopped working ("No wifi adapter found"). Ethernet is working fine though.

I have tried several options to resolve it (especially this and this), but none of them worked. Secure boot and fast boot options are disabled.

I have noticed that bluetooth isn't working either (i don't know if both problems can be linked).

I am far from being an expert, so any help is welcome. Thanks :)

Update

I updated to ubuntu 22.04, which did not fix the issue (kernel version is 6.2).

The init command of the driver seems to fail : output of journalctl -b | grep -iE '02:00.0|mt7921e'

Update 2 I updated my kernel to version 6.5.1, i still have the "No wifi adapter found" error, however the error messages changed :

Update 3 It finally worked after the kernel update and switching off my computer, waiting a few minutes and turning it on again (instead of reboot).

You seem to be suffering from this bug: https://github.com/torvalds/linux/commit/525c469e5de9bf7e53574396196e80fc716ac9eb. As a solution try updating your kernel to version 6.5 — R A, Sep 06 '23 at 08:07
Try this: https://github.com/openwrt/mt76/issues/548#issuecomment-860083371 — R A, Sep 06 '23 at 12:34
Is it reported as MT7922 in lspci now? If so I guess you should update the title — R A, Sep 06 '23 at 13:31

Following RA suggestions, i updated the kernel version and then powered off my computer and waited for a few minutes before turning it on again (instead of reboot).

I tried many things from others topics in the web. No solution specific to a unique post worked for me.

I'm using a new laptop:

Asus rog flow x13 GV302x
AMD Ryzen 9 7940HS w/ Radeon 780M Graphics
RTX 4060

I had the same output from sudo lshw -C network as @atik

and my Network Controller from sudo lspci -nn is :

06:00.0 Network controller [0280]: MEDIATEK Corp. Device [14c3:0616]

I just find a way to have a Network wifi adapter enabled and i'm now connected to internet.

First i decided to install a fresh 22.04LTS version of Ubuntu using a dual boot with a Windows 11.

Secondly i updated my kernel version as @atik did in his post:

$ uname -rms
Linux 6.5.1-060501-generic x86_64

To install this version i used mainline kernels

(ps: If ubuntu is still in the previous version, make sure to run via the "Advanced option for Ubuntu" and then choose the version you want to launch. Make sure to disable fast boot and secure boot in the bios of your PC)

Then, i tried to shutdown and boot the PC in this version of Kernel but it still "No wifi adapter found". So i tried to do what this post said.

After creating and editing sudo nano /etc/modprobe.d/mt7921e.conf with this line:

alias pci:v000014C3d00000608xsv*sd*bc*sc*i* mt7921e

and sudo nano /etc/udev/rules.d/99-mt7921e.rules with this line:

SUBSYSTEM=="drivers", DEVPATH=="/bus/pci/drivers/mt7921e", ATTR{new_id}="14c3 0608"

But after shutdown and boot Ubuntu, it still "No wifi adapter found". Then i did many research on the web, and i find this post who it's said Shut it down, remove power cord and battery(if possible), then press and hold power key for 30 seconds. Put back together and boot

I pressed my power button during 30 seconds and the pc reboot automatically. After thiss step, i just had my Wifi enabled, and it succeed to connect to internet.

when i re-run this command sudo lswh -C network i have now a new configuration part:

*-network

I don't know if this can help some peoples, but I think that following these steps was enough for me to solve my problem, so please keep me informed if this is the case for you.
