Glow IHD disconnects/reconnects from WiFi roughly every 10 mins

While updating my Syslog server for my home network I noticed that for a very long time the Glow IHD has been following a pattern on connecting to WiFi and then disconnecting after about ten minutes and then shortly after reconnects.

I have four UniFi APs covering my home (channel overlap isn't an issue) and have tried moving it to another AP model and checked settings to ensure its not from the AP side and I cannot see any cause. The GlowIHD has an excellent signal as the nearest AP is in the same room and its the only 2.4Ghz device connecting to that AP.

Is this part of the firmware design?

Note: I did consider an Ethernet IHD recently but their dependency on online configuration was a showstopper for me.
