Nest Wifi routers creating multiple Thread networks

[nevi]

HI eveyone

I have a problem with my Nest wifi routers creating their own Thread networks. I have 4 routers, 1 point, and a few other Nest devices.

The 4 routers each create their own Thread network (I can see this from Home Assistant), while the point and other Nest devices join the common network that other non-Google devices have joined.

I've tried factory resetting twice, and each time I reinstate the network, the routers create new random networks. So I have 5 NEST-PAN Thread networks. Ideally, I'd like to have 1 network.

Does anyone know a reliable way to migrate the routers into the 1 common network?

Thanks

Hi @nevi,

Thanks for reaching out to the Google Nest community. I'm sorry to hear that your four Nest WiFi routers and one point are having problems creating their own Thread networks. I'd be happy to provide some guidance.

I appreciate your effort in performing troubleshooting steps. To help provide you with the correct information, I'd like to ask you a few questions: 

• When did the issue start?
•  Are the devices connected to the same network? 
• Do the devices indicate any error messages? 
• Do all devices show up in the Google Home app?
•  In the WiFi settings, does the network name appear multiple times?

Any additional details you can provide will be helpful.

Best regards,

Gabriela

Hi @GabrielaG 

• The issue started when I created a new home on Google Home, so about a month ago. Although I reset all my devices including routers, my old Thread network from my previous home seems to have persisted.
• Yes, all devices are connected to the same Wifi network
• Devices don't indicate error messages, but my Matter Thread devices often appear offline on Google Home
• Yes, all routers show up on Google Home, their connection is all strong.
• Thread networks don't appear in WiFi settings, so no, only the WiFi network name appears, and once.

Home Assistant has a Thread configuration that lists all the Thread networks that are available, that's how I see the 4 routers' individual networks. See below. The expected process is for Google Home to join all the Nest routers into the same Thread network as border routers. Right now my network is just fragmented.

Hi @nevi,

Thank you for your reply. I appreciate the information you provided me about your Thread networks. I'm happy to continue assisting you.

I need to clarify some information to help you with the correct troubleshooting steps:

• Are your Matter devices having problems connecting to the network, or are they just showing offline in the Google Home app?
• Do you have another Home created in the Google Home app? If so, can you please delete the extra Home?

I'll look forward to your response.

Regards,

Gabriela
