A web search for this chip ID led here:

so, it's supported, it just needs some tweaking as outlined in the link above.

Thank you so much could you help me how to do it I'm new on arch

The above link provides two file names and content to put in those files. Create the files and copy-paste the content. There's really not much more help I can provide.

Thank you I try
Do I practically have to execute these commands?

sudo apt install build-essential flex bison
wget https://gitlab.com/jeremy53561/backports-11-26/-/raw/main/backports-5.15-rc6-1.tar.gz
tar -xvf backports-5.15-rc6-1.tar.gz
cd backports-5.15-rc6-1
make clean
make defconfig-wifi

sudo wget https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/plain/mediatek/WIFI_RAM_CODE_MT7961_1.bin

No, that's not what I linked to! :confused:

Look at it again.

I can't figure out how to do it
not and that you could show me step by step how to do it
forgive me

  • In a terminal, type sudo micro and the filename at 1 (and to be clear, cat is a command, not the filename), then press enter.
  • Copy-paste the text at 2. Save the file and exit.
  • Use sudo micro with the filename at 3.
  • Copy-paste the text at 4. Save the file and exit.
  • Reboot.

I did as described but it still doesn't go :sleepy:

The answer @jonathon linked is a few months old, perhaps those files are no longer required on the newest mainline kernel. I would install and test the linux-mainline kernel as it's possible it may now have better support for your adapter.

To install the linux-mainline kernel and headers:

sudo pacman -Syu linux-mainline linux-mainline-headers

You can switch to the newly installed kernel after a reboot via the grub "Advanced" boot menu. After installing a new kernel it is best not to uninstall your old kernel. It is always best to have at least two kernels installed in case one kernel experiences a problem booting. The LTS kernel is the recommended choice to keep installed as a backup kernel.

If the kernel change doesn't help then I guess it's back to creating the udev/modprobe rules. This Archwiki contains an entry on your adapter with far simpler instructions to implement the workaround:


modprobe rule

echo alias pci:v000014C3d00000608sv*sd*bc*sc*i* mt7921e >> /etc/modprobe.d/rz608.conf

udev rule

echo SUBSYSTEM=="drivers", DEVPATH=="/bus/pci/drivers/mt7921e", ATTR{new_id}="14c3 0608" >> /etc/udev/rules.d/99-rz608.rules

Simply execute both of those commands as root (su to root) and the files will automagically be created for you, (then reboot).


Can confirm it's in 5.17rc5: kernel/git/torvalds/linux.git - Linux kernel source tree

(It's not in 5.16.10: pci.c « mt7921 « mt76 « mediatek « wireless « net « drivers - kernel/git/stable/linux.git - Linux kernel stable tree)


Also worth mentioning, this particular wifi card, the hardware and/or the driver, in both Windows and Linux, is notoriously buggy.

Why would Asus put a crappy Wifi card on a premium-ish laptop?? Supply shortage? Intel AX210/201 is better.


from the terminal I ran these commands but it gives me an error

First of all I don't have a laptop but a desktop with ASUSTeK motherboard model: ROG STRIX B550-F GAMING WIFI II
then on windows also the band 6 works perfectly

This means you did not execute the command as "root" as I instructed you to do.

Do not use sudo, use su. Enter su in terminal first, then the root password, then run the commands.

I'm sorry you're right
So I ran the two commands as indicated, but I still can't see the wifi, only ethernet works

Your MOBO's Ethernet also has big issues and is not functional in Linux from other posts I'd read while searching your wifi.

ethernet works perfectly, I feel like drivers are missing wifi

You cannot grasp what is going on here. Your wifi to too new to have proper kernel support yet. The "driver" is included in the kernel. The kernels in general usage do not support this wifi adapter yet. Support is coming and is just around the corner.

Wait for kernel support to be added.

We are going around in circles here. There is nothing more to be done ATM. Nothing more can be added to this thread to resolve a lack a lack of kernel support. Research your purchase more carefully regarding full Linux support if you intend to run Linux.

I am closing this thread now as there is nothing further that can be done for you.
