XT9 mesh nodes frequent reboots

[sirblade]

I have 3 Asus XT9's. One starter set with 2 units and one extra unit. The unit running as the router is running fine. But the 2 units running as AI mesh access point are rebooting themselves regularly, often at the same time. I've been in contact with Asus support, gotten a new starter set, turned off as many features as possible but they're still unreliable. I have SSH access to the units, but since I'm not a linux/networking export that doesn't help me much. Can anyone point me towards a solution? Doesn't have to be a full solution, as long as it's something I can get started with.

Things I found so far that seem to make it more stable:

2.4 GHz
Set channel bandwidth to 20 MHz
Control channel to 11
Roaming Assistant Enable Disconnect clients with RSSI lower than : -80 dBm

5.1 GHz-1: disable 160 Mhz and set control channel to 64

control channel to 64

I don't know why your nodes reboot, but this control channel is in DFS range. Your Wi-Fi may be interrupted by radar signal detected.

I used to see some messages in the log about radar till I switched of 160 Mhz and set the control channel. I'll try another channel.

/edit: switched from 64 to 36
