RBK753 why does reset router needed to reconnect dropped device? (Lennox S30 thermostat)
Periodically one of my Lennox S30 thermostats will drop WiFi connection. When I try to reconnect it is unsuccessful and times out. However if I go to the Orbi and do a router reset, and then try to reconnect it will connect on the first try. What's going on? The signal to the S30 themostat is quite strong and shows an RSSI of -42dbm. I'm aware the thermostat Wifi hub is located between the primary Orbi router, and the first wired mesh Orbi satellite. The thermostat when it has lost Wifi will easily see the WiFi to connect to since it's a strong signal, but the router connection attempt times out, like it has been blocked. I've looked at logs and blocked devices and don't see anything obvious.
But...reset the router and it will connect first time. What's going on? Suggestions?

What do you mean by a router reset. Reset usually means that you factory reset the system and setup from scratch.
What Firmware version is currently loaded?
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?What is the size of your home? Sq Ft?
What is the distance between the router and 📡 satellite(s)? 30 feet or more is recommended in between RBR and RBS📡 to begin with depending upon building materials when wirelessly connected.
https://kb.netgear.com/31029/Where-should-I-place-my-Orbi-satellite 📡What channels are you using? Auto? Try Auto and 48 on 5Ghz. Or try setting manual channel 1, 6 or 11 on 2.4Ghz and 40 to 48 channel on 5Ghz.
Any Wifi Neighbors near by? If so, how many?What I mean by reset is actually going onto the orbi admin web interface and doing a Router "Reboot".
When the thermostat shows no connection to the WiFi (it got dropped), going to that device and trying to reconnect fails. The network shows plenty of signal strength (-40dbm or so), however you can try and try again and it will simply timeout, connection failed. However if I go to the Orbi admin, and do a router reboot, wait for Orbi to completely come back up and then attempt to connect the thermostat it will connect on the first attempt. It seems like doing the router reboot is flushing something, and then the reconnection attempt is successful. My setup is a Motorola modem (latest) supporting Comcast ISP and Gig speed, very low latency. The thermostat hub is in the attic and probably closest to a wired Orbi satellite, but there is some ductwork and it may see the main Orbi router better which is perhaps 25 feet away.

Thermostat is between Router & Sat1, and the admin web interface for Orbi shows it is connecting to the thermostat on the main Router, 2.4Ghz.
