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.

taciochi commented 3 years ago

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 commented 3 years ago

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

taciochi commented 3 years ago

@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 ?

go2jimmys commented 3 years ago

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)

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!

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

I had TUF A17 mt7961 with a similar issue. Neither wifi nor Bluetooth was working on ubuntu 20.04. Updating to 21.10 fixes the wifi issue. Installing the latest kernel rc release fixed the bluetooth issue as well ( sudo bluetoothctl list output was "No default controller available"):

Thanks for the prompt reply. Shutdown-start trick works for my wifi. I haven't had any luck with bluetooth though. ~My mouse pad's right click doesn't work.~ (seems default mouse pad setting is multiple finger) Those are my issues as far as I know at the moment. I believe my ethernet issue should be resolved once this commit is released in stable kernel - already tagged to 5.15.

So sorry, I didn't find the time to test and I installed windows on it. Now I installed ubuntu 21.10 on dual boot with UEFI and wifi works as intended. My kernel version is the following:

Bluetooth still doesn't work.

Glad to know that wifi trick works for you as well. Ethernet one should go away with 5.15 kernel as that added the newer card that is present in G15 to r8169 module https://github.com/torvalds/linux/commit/72f898ca0ab85fde6facf78b14d9f67a4a7b32d1#diff-9d61beebd4949ecbf8877624e7f25547715934c98cf968bed6e3a6d47d797a7f there is new fix to the same module in 5.16 soon to be released

I understand this isn't explicitly related to the topic but since we're discussing ASUS ubuntu issues - I updated to ubuntu 21.10 and the only working kernel I can seem to use is 5.12.16 - kernel 5.13 (default for Ub 21.10) leads to a blank/frozen terminal screen on load. kernel 5.15+ blank terminal screen as well. smells like a graphics driver issue, not sure if anyone has found the magic kernel past 5.12.16 to get this bad boy to load.

That's very weird, is that the AMD+AMD system or AMD+NVIDIA? If it's the former try and capture the dmesg and you can report the bug at https://gitlab.freedesktop.org/drm/amd/-/issues, if it's nVidia have you made sure you've got a matching nvidia module for that kernel?

divine-comedian commented 2 years ago

@FireBurn

Using the ubuntu drivers tool I updated the proprietary nvidia drivers from 470 -> 495 and now it works on the default kernel for impish indri (5.13) but no further - (5.15+ still breaks).

FireBurn commented 2 years ago

Probably best to raise a bug on the ubuntu bug tracker, give them your dmesg too, and just check that the kernel you've installed has a matching nvidia entry in /lib/modules/{kernel version}, at a guess I'd think that the nvidia proprietary module hasn't been generated for the matching version

I have an Asus Vivobook pro 15, with mediatek WiFi ( mt7921e driver). With kernel 5.15.13, WiFi and Bluetooth work perfect but after suspend WiFi not working. Bluetooth continue to work as expected after suspend. Also if I try to shutdown, not work and I need to press power button for few seconds to force shutdown. I tried to install version 5.16 but failed to start with it. I have dual boot with win10, I try it with fast boot disabled and enabled, no difference. Only solution for moment is to disable suspend and hibernate.

Now with kernel 5.16.1-zen1-1-zen, a sleep would lead to a crash, and modprobe -r mt7921e would not work.

A simple but dirty way to fix: put this file in /usr/lib/systemd/system-sleep/, name it as mt7921e_fix or whatever.

#!/bin/sh

# manually unload and load mt7921e to avoid problem after sleep

case $1 in
    pre)  modprobe -r mt7921e  ;;
    post) modprobe mt7921e  ;;
esac

This file automatically unload the mt7961e before sleep and load it back after waking up.

Tested with 5.16.1 and still not work wifi after suspend. A simple but dirty way to fix: put this file in /usr/lib/systemd/system-sleep/, name it as mt7921e_fix or whatever. I know about this solution but in my case not work (kernel 5.15.13 or 14 I don't remember exactly). What version of the kernel works best for you with the above solution?

I mainly use linux-zen 5.16.1.zen1-1, and I did a test with linux 5.16.1.arch1-1, both works. By the way, I am using Arch Linux and only sleep works. I have fatal problem with hibernate, not sure why because I seldom use hibernate. The file may need 755 permission. Maybe you can manually test it by run sudo modprobe -r mt7921e and then sleep, and then wake up the computer and run sudo modprobe mt7921e

I have a MSI Modern 14 B5m laptop and running a dual boot (Windows and Arch). I managed to make my Wi-Fi worked by following this answer before.

But recently after I updated my kernel to 5.16.arch1-1, it keeps making the kernel to panic (my journalctl -b -1 logged mt7921e 0000:01:00.0: Timeout for driver own). I'm currently running the linux-lts kernel version 5.15.15-1, although sometimes, it randomly stopped working. But I could fix it by updating my laptop firmware on Windows.

Edit: Link to my hw-probe

vlad2005 commented 2 years ago

I use Ubuntu 20.04, and for me, removing kernel module not work. I test first before any suspend (fresh start). Remove kernel module, then load again, everything work perfect. Then I remove kernel, go to suspend and back, But when i try to load kernel module nothing happens.

After 6 months they finally fixed it

Kernel patch: https://patchwork.kernel.org/project/linux-wireless/patch/70e27cbc652cbdb78277b9c691a3a5ba02653afb.1641540175.git.objelf@gmail.com/

WARNING: this patch could be buggy, recommended to only build mt76 as a module; see the mailing list

FireBurn commented 2 years ago

The kernel refuses to boot with this applied

nullchilly commented 2 years ago

@FireBurn I added a warning

It seems like things are finally moving quite a bit for the mediatek driver: https://patchwork.kernel.org/project/linux-mediatek/list/?submitter=169671. It should be fixed in the next release cycle.

For ubuntu folks, the fix is included in the staging firmware https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1958286

vlad2005 commented 2 years ago

How to test this firmware or when will be available for non geeks? I test until now kernels from here: https://kernel.ubuntu.com/~kernel-ppa/mainline/ but it's a bit to much to download source code, apply patch, compile, ......

poupryc commented 2 years ago

Some users (myself included) are seeing their system stability fall apart with the latest kernel 5.16.3 update on arch https://bbs.archlinux.org/viewtopic.php?pid=2019011

vlad2005 commented 2 years ago

For me (Ubuntu 20.04) the latest kernel versions don't even boot (5.16.3, 5.16.4, 5.15.16-18). I even updated from 20.04 to 21.10, but without success (with wifi).

Edit later: After new tests, it seems that boot with 5.16.3 / 4 and 5.15.18 but wifi does not work. Boot time takes longer than normal. For me, the latest version where wifi works properly, except suspend is version 5.15.14

9prady9 commented 2 years ago

I have 5.16.3-arch1-1 now on Arch Linux with that update what used to work stopped working completely now

aelzenaar commented 2 years ago

On Arch too with an Asus TUF506LH, 5.16.3 is totally broken for me (it panics 50% of the time on boot due to the mt7921e driver and the other 50% it boots but the network stack seems to be completely broken), I tried the lts kernel (5.15.17) and it is also not working (now it boots almost every time but mt7921e is still broken)!

I burned a new live disc yesterday and when booting from there I could connect to wifi using iwd; rebooting back into my permanent install then messes up the wlan chip state, and if I boot back into the live disc iwd no longer works. To get it to work again I have to reset the firmware (unplug adapter & hold power button for 60sec, as in https://forums.linuxmint.com/viewtopic.php?t=349575).

In any case here is another relevant bug report not linked above. https://lore.kernel.org/all/YfY+C9hiX2V7LnT6@kroah.com/t/

@aelzenaar I'm on arch as well and 5.16.3 and 5.16.4 were completely broken for me on the a Lenovo P14s. The mt7921e WiFi didn't work and the amdgpu caused issues as well, including troubles entering standby.

I tried the lts kernel (5.15.17) and it is also not working (now it boots almost every time but mt7921e is still broken)!

5.15.18-1-lts works for me, it boots without problems and wifi and amdgpu seem to work without problems so far.
