Frequent Disconnects

[jplw]

I have an RT-AX300 Router and RT-AX82U AiMesh node. I have a device (a Harmony Hub) with MAC address 00:04:20:F3:7E:09 connected to it from 6 feet away. The hub is bound to the 82U. It disconnects several times per day, with messages like this in the log (these messages are after a system reboot about an hour ago):

Dec 17 09:59:15 wlceventd: wlceventd_proc_event(685): eth2: Auth 00:04:20:F3:7E:09, status: Successful (0), rssi:0

Any ideas what the problem could be?

rssi:-86

This device has very low signal for some reason.

Thanks, but I wonder why it changes? It just sits there--untouched--and then disconects and reconnects.

According to logs this device is somewhere around the edges of usable signal area. What is blocking the signal - I don't know.
