Types of Wi-Fi networks that aren't recommended or won't work with Nest products
Nest products use Wi-Fi to send notifications. A wireless internet connection also means you can remotely control your products with the Nest app. For the best experience, avoid connecting to the following networks if you can. These networks may cause issues, or might not even work with your Nest products at all.
A mobile hotspot allows your phone, tablet, or other mobile device to share its cellular internet connection with other devices. While it’s possible to connect Nest products to a mobile hotspot, we don’t recommend it.
A mobile hotspot can have issues with bandwidth, availability, data limits and usage fees. Nest products work best with a reliable 24/7 internet connection, so you’d need to keep your mobile hotspot device at home all the time. For instance, if your Nest products don’t have a continuous internet connection, you won’t be able to view their status or receive certain notifications to your phone.
Guest networks, open networks, or isolated networks
For security reasons, never connect your Nest product to a network you know nothing about, and don’t use someone else’s network without their permission.
You shouldn’t use a guest network, even if you have permission from the owner. If you run into problems while using someone else’s guest network, you might not be able to fully troubleshoot the issue. For example, you won’t be able to change the settings on someone else’s network. And the owner can change their settings and add new restrictions without telling you, which may cause your Nest products to disconnect.
Some routers have wireless isolation settings. These settings will prevent devices on your network from connecting to other devices in your home. Since Nest products talk to each other during pairing, setup, and during daily use, they may not work properly with these settings enabled on your router.
5GHz Wi-Fi networks (a few Nest products don't support 5GHz)
Some Nest products, like the 2nd generation Nest Thermostat, only support 2.4GHz Wi-Fi networks. So if you’re trying to connect one of these products to Wi-Fi with the Nest app, you won’t see any 5GHz-only networks in the list of available networks. The Nest app knows they’re not compatible, so it won’t display them.
Note: If your Nest product supports 5GHz Wi-Fi, then you won't run into this issue. To see a list of Nest products and their supported Wi-Fi connections, see the following article.
Captive portal networks
Captive portal networks are common in airports, hotels, internet cafes, and coffee shops. On these networks, you must sign in on a web page, and sometimes accept terms and conditions, before you can connect.
Nest products do not work with captive portal networks. There’s no way for a Nest product to sign in on a web page.
Important: This is different from manually entering an SSID and password for a hidden network, which Nest products are capable of doing during setup.
Enterprise 802.1x/RADIUS networks
Nest products do not support enterprise-class networks. These networks are typically used by large-scale businesses.
