AI mesh keeps switching between nodes

[KG49]

Within the last month my ASUS mesh network keeps switching my Apple products between the base (RT-AX86U Pro) and the node (RT-AX55) with multiple seconds of no connection in between. I notice this happening in one area of my house where I spend a lot of time. It may happen in other areas, Idk. Seems to be a recent issue.

Anyone else have this issue?

Can I change a setting to stop this behavior?

Everything has the most recent updates.

It's probably best to look at the system log and see at what RSSI it is moving from one to the other.  The setting is default to -70...

Here's a sample of the log. I replaced the actual MAC address of the iPhone with "iPhone MAC address".

How can I adjust the RSSI threshold for switching nodes?

It seems, (I am not an expert at reading the logs),  that the device leaves one station due to poor signal but can not connect to the nearer station.  I'm not sure which station is which, but I would delete the RT-AX55 from AiMesh, hard/factory reset it, and then add it back as an AiMesh node...
