Replaced thermostat connects to WiFi now cannot see network

[PaulSpn1]

8 days ago, my Nest E learning Thermostat stopped connecting to my Google WiFi network, all that was there was a w5 error code  I received another replacement thermostat it arrived and I started to configure it.

I was able to see all available networks, and I could connect to my home network. Then proceeded to complete the setup, after which I have lost connection to the thermostat from the nest app and WiFi is no longer available on the replacement thermostat.

Initially I was thinking firmware, but nothing has been applied, I have tried resetting the device, restarting it, removing the network, and still no networks can be found when searching for the networks. Originally, there were loads of possible network connections.

Anyone else experiencing issues like this?

I did

The w5 error is basically “I can’t find a network” Sounds as though the replacement unit is also borked.

You should call Google again.

Hi folks,

Thanks for chiming in, @SeriouslyWhy. 

@PaulSpn1, yikes! I'm sorry to hear that your replacement thermostat is still giving you a W5 error code. If this is the case, I recommend you contact your Internet Service Provider (ISP) or router manufacturer to check on the connectivity from your router to the thermostat. Here are the most important recommended Wi-Fi network and router settings for use with Nest products. For more details, refer to the sections below.

• Enable 802.11 b/g/n if you have an 802.11 ac router.
• Set your Wi-Fi router's DHCP lease time to at least 2 hours.
• Turn on your router's Power Save Mode (PSM), if you have a Nest Thermostat.
• Enable IPv6, if you have a Nest Protect.
• On your Wi-Fi router, turn on multicast, if you're adding additional Nest devices.

Keep us posted. We're happy to help.

Best,

Zoe
