Xiaomi AX3600 clients not connecting to 2.4G wifi

Installing and Using OpenWrt

Hi! I own two Xiaomi AX3600 since a lot of time ago. They worked as expected. One is the main router and the other acts as AP.
But from some weeks ago, the 2.4 GHz wifi network of the main router have some problem. I will try to explain:

  • I've the same SSID with the same configuration in both devices, for the 2.4GHz network.
config wifi-iface 'wifinet3'
        option device 'radio2'
        option network 'lan'
        option mode 'ap'
        option ssid 'PIMINET_N'
        option ifname 'wlan24g'
        option key 'XXXXXXXX'
        option encryption 'psk2'
  • The clients usually connect to the nearest one.
  • From some time ago, I observed that the main router has 0 clients on this network, despite some clients are just next to this router. All the clients are connected on the AP router that is further.
  • If I force the clients to connect to the main router (disconnecting them from the AP), they seem to connect, but the speed is zero. It's like they can't send or receive data:

  • The result is that some seconds later, this devices disconnect from the main router and connect to the AP again. The main reason seems that they don't receive anything, I've this on the logs for all the devices:
Thu Dec 19 07:54:50 2024 daemon.notice hostapd: wlan24g: STA xx:xx:xx:xx:xx:xx IEEE 802.11: did not acknowledge authentication response

Some idea of what is happening? Now I'm on 24.10.0-rc2, but happens too with latest master and earlier ones. Thanks!

It seems the problem is fixed... after removing some frames with photos that are near the router, the devices connect again without problem.
It's that casuality or the frames produce a lot of interferences/occlusions? I will do more tests to try to confirm this.

It seems it wasn't the photo frames. After some tests it seemed that when moving the photo frames I moved a little the router and this make the devices connect... But after some minutes they disconnect again and move to the other AP.

Now I tried to change the channel and it seems more stable. 24 hours later the devices remain connected to the router.

EDIT: I can confirm that they are more or less stable with the new channel, so it seems the culprit is some kind of big interference in the channel 6 at the router location (but not at the AP location).
