Cannot connect my Carrier Infinity Thermostat

[HR21]

I have a Carrier Infinity Thermostat that used to connect to internet with no problems on my previous 2 routers (Previous Century Link and Netgear routers). Now, it cannot connect to my Orbi, despite that it shows on my connected devices list when I log into my orbi router.

Anybody else had this problem? Any solutions?

Have you checked if it needs to be connected to a certain band at all times some smart devices do not like mesh networks.

I had that problem with my Ring devices.  It turns out they are on 2.4 GHz only and need a channel between 1-11.  I set the channel manually and it works well now.  You could try that.

Thanks for the tip. I tried to maulay select the 2.5G band to channels 1, 6 and 11.. tried all 3 but did not work.

One more thing I need to change in my original post. I actually cannot see it connected ever on my device list when I log in to my router.

Look for the post on here by @khad showing how to create separate SSIDs for 2.4 and 5 GHz.  Create separate SSIDs. Connect thermostat to one SSID (probably only works on 2.4G).  Then you can see if it stays connected after restoring to a single SSID.
