Ubuntu 22.04 WiFi driver not found: Mediatek mt7921e

[diasbalmash]

Thanx guys for the solution! same problem on HP ZBook 14 G10A
I disabled BIOS: "preboot wifi" and "fast boot". now it works perfectly!

Is your laptop with dual boot mode?

 

[Arhil]

I have similiar problem, what do i need to post i tried many things nothing seems to work. I have Asus Tuf Gaming A15 FA506IC. network driver mt7921e, it ocassionaly turns off and i need to reboot, i have a dual boot with W11.

Have you tried disabling windows secure boot?

 

[Arhil]

booting in insecure mode, and fast boot disabled

 

[Brickwizard]

this has been an ongoing problem with this particular MediaTek card, one possible solution to try [from last year]

Mediatek MT7921 WIFI keeps disconnecting. - Linux Mint Forums

 

[Arhil]

i will try that and let You know if it works

 

[Arhil]

i didn't even had a firmware folder usr/lib used

• dpkg -l | grep -E 'linux-firmware|wireless-regdb'
  
  sudo apt remove --purge wireless-regdb
• sudo apt install --reinstall linux-firmware
  will see

 

[Arhil]

so evereything went sideways after previous steps drivers were installed but nothing worked, wifi was disabled and bt also. drivers for screen also went missing. very bad combination, finally reinstalled ubuntu 22.04 and for now it works, and boot options that i installed GNU Grab i think finally apears at the start of PC

I had a HP 465 G11 with this Mediatek wifi running Ubuntu 24.04. No 5GHz connection possible, and with 2.4GHz only 22Mbit download.

Now I have simply replaced with Intel Wi-Fi 6E AX210 / Wi-Fi adaptér / M.2 2230 / 802.11ax / Dual-Band 2.4+5+6GHz / Bluetooth 5.2 / M.2/A-E Key.

Now running 450Mbit. So, just replace!

... btw. don't upgrade kernel to 6.11. with the hope to fix the Mediatek issue! It do not fix it. :-(
Instead the display stops working after wake-up plus kernel issue reports. Stay with kernel 6.8.0-45-generic

this Mediatek

Only good thing I have found with MediaTek products, is they make media start [MSI] look dammed awful, I will never buy products by either of them.

I hate Mediatek they cause more problems than RTL, I was expecting a second line on device 2 saying state up or down.
I assume its a laptop of some sort. Occasionally when installing Linux on some machines, it will go into hard block [quite common on Acer] as it is showing a mt driver installed, First thing is to check if a hard block [flight mode] is activated.

Welcome to the forums
can you post the FULL report of inxi -Nnz ?

hello sir ,can you help me too,i am a newbie .I am also facing issue with wifi adaptor,mt7902 ,Asus vivobook GO15 ,ubuntu 24.04.01

 

[Brickwizard]

hello sir ,can you help me too,i am a newbie

Welcome
from the terminal, can you run inxi -Nn and paste back the results

Things have changed a bit in the last 6 months you will need alternative means of connecting to the web, [Ethernet or teatherd mobile]

Getting GitHub Wi-Fi driver for MediaTek MT7902 card working on Linux

This article provides instructions on how to get the GitHub Wi-Fi driver for MediaTek MT7902 card working on Linux. Currently, a USB adapter (TP-Link AC600 wireless Archer T2U Nano) with the rtl8821au module is working well. The goal is to get a driver for the MediaTek MT7902 Wi-Fi card.

same issue. Currently it is working, but after some time wifi stops. And while shut down i can see logs - Mt7921 driver own failed. Do i need to get a new wifi card?

 

[dos2unix]

I never have any problems with mine.

@aryankb27 - see my signature for wifi info dumps

I had a similar problem when I was using MX linux - ended up replacing my network adapter (which was getting old anyway) and switching to a different distro. not sure what distro you're using, but I have been very happy with Arch (and KDE)

if you have usb3.x ports, consider using a usb wifi adapter.

What distribution are you using and which kernel?

Hello; hoping I'm not breaking any necropost rules here, this post seems recent enough. I have been experiencing nearly identical issues as @aryankb27 above on my ASUS TUF A15 FA506QM for about 3 to 4 weeks, maybe more, but mine are a bit more severe: it tended to happen after an hour or two of usage or sometimes right on boot, but instead of merely stopping network access, it will also prevent me from disconnecting from the Wi-Fi network or using Ethernet, and it also creates a ton of processes that sometimes take up much of my CPU. Once that happens, a kernel panic will likely occur. If I shut down before then, WPA supplicant and NetworkManager will take two or three minutes to complete their stop job and then I'll see that same "mt7921e driver own failed" error, after which the laptop doesn't shut down properly, just stays on a black unpowered screen while remaining powered. I have to force shutdown.

I am running EndeavourOS, but I'm not sure it's actually relevant, because worryingly, this occurred even on a live USB. I tried Fedora KDE on two different thumb sticks first and both kernel panicked soon after reaching the desktop; then I tried EndeavourOS and had the same issue as my own system. This got me thinking it was a recent kernel problem, but I've tried a handful of versions from 6.13.8 (seemed to work before) to 6.14.4, on linux, linux-lts and linux-g14 from the ASUS-Linux project, and none of these kernels seemed to fix it ; I think I noticed linux 6.14.3 being slightly more stable, but that could be placebo.

The one solution I found was to blacklist mt7921e entirely, which has worked perfectly so far. I've been relying on Ethernet for now, but that's not always convenient, especially for work. If anyone has a fix, I would be glad for it. Otherwise, I think I'll get a dongle or replace with an Intel AX210 as I've seen suggested.

Some logs and outputs:

• sample kernel panic report (thanks Arch for adding this new QR code feature)
• linux-hardware.org probe
• inxi -Nnz
• dmesg
• journalctl -u NetworkManager -b 0 (context: on that boot, I used the machine normally with a wired connection until the error occured, and then I tried to disconnect from the Wi-Fi)
• ps -ef (showcases unusual napy/phy0-0 and ksoftirqd processes which can take up much of the CPU)

As a sidenote, a battery life increase from blacklisting the driver can be expected, but in this case, it's been TREMENDOUS: more than twice the battery life as far as I can tell. I would never have guessed. I assume it must mean a lot about how awful this card and driver really are.

Purchasing a new wifi adapter worked for me. It instantly connects the wifi and keeps it on for days. The problem is gone.

based on your diagnostics (and the fact that you experience the issue in a live image), I agree that the wifi chip is going bad. replacing it with a different wifi module is the right way to go for a laptop (if you're ok with cracking the case open & swapping it out )

the increase of battery charge is an interesting side effect!
