Adding OpenWrt support for Xiaomi "Redmi Router AX6S"/"Xiaomi Router AX3200"

I did on the latest development release, dirty flash, wifi working for me in dumb access point but, i don't recommand doing it as being problem free.
Build is: r21900-ac21dff5b6, flashed the sysupgrade way.

So, I used the Mediatek drivers for a couple days, and performance was amazing.

Today I finally got my fiber service installed, during the install I unplugged the router, and after that my Wifi wont come up at all.

I flashed the 22.03.02 from firmware selector and I got 2.4Ghz working again, but 5Ghz isn't working at all.

EDIT: After setting the 5Ghz to channel 44 it works fine.
Did a reboot and I still have working WiFi.
No ideia why the Mediatek drivers leave with no working WiFi.

Hi poyz,
sorry for the late answer. I went from 22.03.02 to 22.03.03. I used the official build I downloaded from
Please keep in mind that if you're upgrading you should use the " [Firmware OpenWrt Upgrade]" version. For openwrt 22.03.03. The direct link is:
I hope everything will be good for you. Keep us informed.

do you compiled the firmware? or ....

Hi everyone,

I installed openwrt today, but the wifi is very unstable,
The speeds are worse than on my mi 4ac gigabit,

Is it normal?
I have the rb01 model

Try snapshot build. It work very good with my device

What results do you have with iperf3?

Are you using 802.11ax? If so, try switching to 802.11ac. This and some other devices have issues with 802.11ax and OpenWrt in certain conditions (see below and more details here in this other topic).

Running stock openWrt, from the firmware selector, and then added the Mediatek drivers from this Mega folder:

It worked perfectly for a week or two, during that time I never rebooted my router. Once I did a reboot it never worked again.
The WiFi interfaces after booting would be both disabled, I could enable 2.4Ghz, but not 5Ghz.

And its not good to lose WiFi after a reboot.

well, never happened on my build,i do not know why that.
