Carrier Touch thermostat "A" will not connect to Orbi RBR850
TLDR: Our Carrier Infinity Touch version "A" thermostat will no longer connect to our Orbi RBR850 or its satellite RBS850s after rebooting then resetting them. The thermostat connected to the Orbi G...

Yes, I've tried the main Orbi network, the IoT network with both 2.4 GHz and 5 GHz and just 2.4 GHz enabled, and the Guest network.
Neither WPA2-PSK [AES] or WPA-PSK [TKIP] + WPA2-PSK [AES] work.
I've done pretty much everything suggested in the search link you posted. The one thing I didn't mention is that Access Control isn't enabled.

Not sure if the others that posted ever got a good resolution aside from installing a 2ndary wireless AP.
Wondering if you installed this 2ndary AP long enough for the device to connect. Set for same SSID name and PW as what is on the Orbi system, then once you get the devices connected to the AP fully, just turn OFF the AP and see if these devices auto migrate and connect to the Orbi signal. I would set the Orbi signal to WPA2 only to help test this as there maybe some wifi devices that do not like having WPA3 on the signal, even though they don't support it, won't connect if it's enabled. Ran in to this early days of my 850. NG removed WPA3 until this was worked out and brought it back in 2023.
I would presume if the devices connect to the 2ndary AP using same SSID name and PW, then turned off, if they don't connect to the Orbi system, maybe some odd connection issue that the device Mfr needs to take a look into with NG. I know we saw bad problems with NEST controllers back in 2020 as well. Caused the NEST batteries to drain due to the controller not keeping locked on to one signal and ping ponging back and forth trying to decide which signal to lock onto since there was many signals coming from the MESH system. NG and NEST had to work on this to get it figured out. Not fully sure if they ever did as one work around for this was to wire connect the controllers to the HVAC system that provided lower power current to the controllers. Ever since making this switch, I haven't looked back. However the controller do connect to Orbi signals. Something this device mfr should take a look into.

Yes, did all this. As I wrote in my initial post, I used both a laptop sharing internet from ethernet to WiFi, and an Apple Time Capsule (a router with a built-in hard drive) in access point mode. Both used WPA2. When connected this way the Carrier app could see and control the thermostat.In both cases the thermostat appeared to stay connected for a few minutes after the laptop and Time Capsule WiFi were turned off. The thermostat showed up in the Orbi's "Attached Devices" after the laptop's and the Time Capsule's WiFi turned off (not before). But after a few minutes the thermostat lost the connection. First it lost the connection to Carrier's server, then it dropped the WiFi connection.
This happens whether I have just the RBR850 on, or have it and both satellites on.
The thermostat will stay connected to the Orbi system if I turn off security. That's not a practical solution, but it could indicate that the Orbi's WPA2 is the issue.
