Next Thermostat No Show on 5G Wifi

Before I added my own router to the Verizon 5G Home, I'd been using the Nest Thermostat on my 5G wifi. But when I took the router out and went back to just the Verizon gateway, I was unable to find the Nest Thermostat on my 5G (only shows up in 2.4G and other devices had no problem).

I rebooted the routers and reset the thermostat to factory settings, but none of them helped. So I read some posts on here and tried adding the thermostat's mac address to the 5G mac address filter on the router, and the thermostat started showing up on the 5G.

What could have happened here? Did the router somehow restrict the thermostat's mac address?

Hi shogodr, 

 

Yikes! Here's an explanation for you.

 

Your Verizon gateway router might have different settings for your MAC address filter as well as different networks (2.4 GHz vs. 5 GHz). MAC address filtering limits the connectivity of certain devices. After switching off your own router and returning to the Verizon gateway, there is a big chance that the system configurations were modified or reset, including the MAC address filtering options. Hence, the Nest Thermostat’s MAC address is most likely missing from the approved device sheet for the 5 GHz network.

By adding the MAC address of your Nest Thermostat to the 5 GHz MAC address filter of the router, you allowed it to access and connect to the 5 GHz network. Therefore, when this change was made, it started showing up on the 5 GHz network. It might be mentioned that 2.4 GHz and 5 GHz are unique wireless units, and if a device is configured for one of these networks, it can’t operate on the other one. At first, the Nest Thermostat might have hooked up with the 5GHz network of your own router as you are using one, though without letting in the MAC address on the 5GHz network of the Verizon gateway, it couldn't connect to it. Therefore, this is solved after adding the MAC address to the 5 GHz MAC address filter, thus enabling the thermostat to connect with the 5 GHz network. It’s a typical occurrence when using a router’s MAC address filter.

 

Let us know if you have any other questions.

 

Best,
