Asus TUF gaming AX6000 LAN ports disconnected

[scream_jojo]

Hello,

For several days I have been experiencing problems. Yesterday the 5ghz band went to 20Mhz (DFS problem?) while I have no neighbors and no other wifi networks nearby. So I changed the wifi configuration and disabled WPA3 on the 5Ghz because there were a lot of error messages like this :

kernel: 7986@C15L1ra0,PMF_PerformRxFrameAction() 1492: [PMF] : NOT_ROBUST_UNICAST_FRAME, FC->SubType=12 (wcid=17)

The router is configured to restart every night automatically.
This morning after the restart the wifi seems to work, the WAN is up and I've internet connection, but I no longer have my 2x others Aimesh router detected (wired connected). My NAS connected to the 2.5Gb port no longer has a connection either, no IP. The network port LEDs are flashing. I can't find anything in the logs that could explain this. Several months ago I had random disconnections on all ports but after changing the network cables no more disconnections.
I had to restart to finally find the connection on the LAN ports.
My firmware version: 3.0.0.4_388_33427
Do you see anything in the logs? https://pastebin.com/tR9XMNG7

Thanks in advance

First, why are you restarting every day? If there is no good reason just let the router run.
Good that the firmware is up to date. You might start with a hard factory reset and manually reconfigure. Do not use a saved settings file. Factory reset the nodes as well.
Leave the WIFI settings at default and use Dual Band SmartConnect.
Do not enable access from the WAN other than with a VPN. Do not use AiCloud.
Get the router set up and running then reconnect the AiMesh nodes.
Might also be a good idea to reflash the current firmware before factory reset.
