Some Issues with Xiaomi AX3000T Running 24.10.0

Installing and Using OpenWrt
1

Hi everyone,

I'm experiencing some wireless issues with my Xiaomi AX3000T running the latest 24.10.0 firmware.

Here's a breakdown of the issues:

  1. 5GHz 160MHz Channel: When I enable the 160MHz channel on the 5GHz radio, the router fails to detect any other devices. It looks like this:

    5G
    5G2130×700 71.7 KB

  2. 2.4GHz 40MHz Channel: Even when I configure the 2.4GHz radio to use the 40MHz channel, it seems to be stuck at 20MHz. The performance suggests it's not actually using the wider channel.

  3. Wireless Client + AP Mode Issues: I tried connecting another router to my AX3000T by wireless client + AP mod. While the 2.4GHz connection works fine, the 5GHz connection consistently fails. And I see a lot of these errors in the system logs:

And also these kernel logs:

Has anyone else encountered these issues with the Xiaomi AX3000T and the 24.10.0 firmware? Any help or suggestions would be greatly appreciated.

Thanks in advance!

I have a similar setup:
AX3000T connected to internet
Ax3000T in client mode connected to the first one via WiFi

several times the connection seems to drop and the devices connected to the second AX3000T cannot reach the mqtt broker connected via lan cable on the first.

It was fine when I was on the previous version + ImmortalWRT, so it started when using 24.10
