I have a network with one mesh master (RUT955, RUT9_R_00.07.06.19) connected to the internet via WAN-Port and 3 mesh slaves (RUT955, RUT9_R_00.07.06.19). All 4 RUT955 are providing an Wifi AP. After some time (randomly after days) all mesh slaves are loosing the connection to the mesh master. The mesh slaves are no longer accessable over RMS in that case. A reboot of the mesh master solves the problem. After the reboot the mesh slaves are connecting again to mesh master. How can I identify the root cause of that problem? I don’t see any problems in the logs of the mesh master.
Hello,
Under the Network → Wireless → Radio settings, I recommend editing the channel you’re using and reducing the channel width to 20MHz instead of 40 (if that’s what you’re using at the moment):
You could also try disabling the Disassociate on low acknowledgement setting under Network → Wireless → SSIDs → “Edit” on the interface → Additional settings
If you have Fast Roaming enabled, try disabling it, or vice-versa, if it’s disabled, try enabling it, see if that improves the situation.

Width was already on 20% (on all 4 devices).
Your second suggestion relates to the Wifi AP not the Mesh Network, right? Because the Wifi Mesh configuration has no Disassociate on low acknowledgement setting. I also don’t find Fast Roaming in the settings. There is 802.11r Fast Transition, is that what you mean?
Hello,
Yes, this is what I had in mind. Apologies.
Besides the fast transition setting being left to check, everything else looks to be good from the configuration end of things. To me, it sounds as if, for some reason, the signals get weaker every once in a while (randomly, every few days, as you mention) and the devices simply disconnect, and end up failing to perform a handshake with the master - perhaps, if you haven’t yet enabled fast transition, you could try doing so?

I have disabled Disassociate on low acknowledgement and enable 802.11r Fast Transition. Let’s see if it improves the stability.
