I need to change the DNS on my Nest learning thermostat

[VegasDon]

There was an issue with ISP which now requires me to change the DNS for my thermostat to get online. All instructions I have say to click the wi-fi icon on the Nest app, but that icon only shows up if the thermostat is on-line, and I can't get it on-line because of the DNS issue. Is there anyway to change it on the thermostat itself?

There isn't a setting on the thermostat to change the DNS it uses. The thermostat gets that information directly from your router. You'd need to change the DNS settings on your router. You can also try resetting the Wifi connection on the thermostat. Follow step "9. Reset your thermostat's Wi-Fi connection" linked below.

my thermostat connects to the router - just not the internet. I've had to change the DNS on my computers and my telephones, Do you work for google/nest?

No, I'm another user just like you. If you change the DNS settings on your router, it will change it for all your devices. Unlike your phone and computers, Nest Thermostat does not have a setting to change the DNS it uses.

Your Wifi router should be supplying DNS settings to your tstat. Change your wifi netrork and then change it back to get new network settings.

The nest thermostat uses DHCP to obtain an IP address from the WiFi router serving your home.  It does not need the DNS programmed manually since the WiFi router will handle the DNS.  Devices on the local network have the WiFi router LAN address as the DNS address to use. Since the LAN of the network uses a non-register address I.e., 192.168.x.x, your WiFi router is the default gateway and the DNS source address. Your WiFi router should get the DNS from the ISP when it attaches to the ISP. If it does not, you need to configure the DNS in the WiFi router for the WAN side, and the DHCP server in the WiFi router will take care of the LAN side.
