I have Windows 10 insalled on this PC as well, and Wi-Fi works fine there.
Fast boot is disabled. Secure boot disabled.

Any suggestions?

[Roman-]

Solved by powering off the laptop (instead of rebooting it)

Following this suggestion, I powered off the laptop (instead of rebooting it) and unplugged the power cable for a few minutes. Then the Wi-Fi adapter magically appeared.
If this is a hardware issue that can't be solved with the drivers, please close my issue.

Hello Roman,

I am fairly new to Ubuntu and Linux in general. I have the same problem on an ASUS TUF F15 and I took the same steps as you have by updating the kernel. For me, sometimes the Wi-Fi works, other times it does not. Apparently, as I found here there are no drivers yet available for our Wi-Fi adapter. I have disabled secure boot and fast boot as said there. Hopefully there will be a driver release soon. As I understand, sometimes if you turn off your laptop and then turn it back on without having a the charger plugged in, the adapter may work. You may also find useful information here. I hope this helps you. If you find better solutions, please contact me and let me know as I am in the same position.

Best wishes,
Teodor-Avram

BTW, is your trackpad working?

[shizonic]

@Ciochirca My trackpad stops working from time to time...

[taciochi]

@shizonic have you tried the instructions here? My issue is that apparently there is a bug in the Linux kernel, but for some reason, I can not report the problem. When I enter the command ubuntu-bug linux I get a pop up with the title "Problem in linux-image-5.12.10-051210-generic" containing the description "The problem can not be reported: This report is about a package that is not installed.". I have read on a couple of forums that it might be an xor problem, but I can not say for sure. I hope you will resolve your problem from the instructions provided by their team.

HI Roman,

Could you help cherry-pick the patch "mt76: mt7921: reset wfsys during hw probe" [1] onto your testing kernel source,
recompile the module and retry again ?

[1] https://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next.git/commit/drivers/net/wireless/mediatek/mt76/mt7921?id=01f7da40917923bf9d8fd8d5c9a6ed646004e47c

[go2jimmys]

Hello I also experience the same problem with the same mt7921 on asus tuf f15. Everytime I reboot the wifi firmware fails to build and load and the wifi icon is missing from the top right corner. It works fine after a shutdown and then boot.

I tried blacklisting the mt7921 modules from modprobe on boot and run the modprobe command manually after boot. I get no errors on command line but again the module seems to initialize normally after a shutdown and does not work after a reboot (failed with error -5 on dmesg).

I will try to build the module using the patch mentioned by objelf and report back (probably tomorrow)

[gasbi]

Hello, I am experiencing the same issue here with the mt7921e on a ROG G15 GA503QS, and I am on Fedora 34 with the custom kernel from asus-ctl (https://asus-linux.org). Setup with a dual boot with Windows 10.

Also, I never got the Bluetooth to work properly; does it work for any of you?

Let me know if I can do anything to help fix this issue, or if you find a solution!

I have ASUS ROG Zephyrus G15, tried fedora 34 with dual boot with kernels 5.11 and 5.12, the same issue for both.(@Ciochirca touchpad didnt work for 5.11 for me, after update it was ok)

Moved to ubuntu 21, updated kernel to 5.13.2. Without power cable wifi works, if I connect a cable and reboot it doesnt.
Bluetooth doesnt work at all for all kernels, distributions, etc

@Ciochirca @shizonic I have TUF F15 and cant get touchpad working. How did you guys resolve this?

[krviolent]

I had got same issue on my Asus F15 as you, Roman, so powering off helped (Ubuntu 20.04 kernel 5.12.5).
But mainly I have issue with Bluetooth adapter, it doesn't work.. (tested also with kernel 5.13.0)

I have the same issue on ASUS ROG Zephyrus M16. Changing my wifi adapter from MT7921 to AX200 doesn't help.

Experience very similar problem with arch on kernel 5.14.5. The kernel panics on reboots and when poweron. A solution that seems to be working is a hard shutdown and then boot.

Couldn't dump the panic logs in a text file. The logs in the image are fairly readable

[patrickjquinn]

Looks like there is a seemingly unrecoverable, driver crash on suspend / resume under arch (5.14)

Before suspend

After Suspend
