I have a Google Nest mesh network in my home. It is comprised of two routers and 3 wifi points. The second router is hard wired to the first via a network cable. I cannot connect to wifi from any device. Any device not connected prior to the problem could connect. After the first power down restart, no devices could reconnect. Support has been absolutely no help and have dumped me twice forcing me to start over with someone new. (If you are wondering, I have been very patient with each support person...)
I can get access on my desktop to the internet via a network cable connected to the main Google Nest wifi router. However, I am "unable to connect to the network" wirelessly. The entire system, including the xfinity router have been restarted, via unplugging the devices, multiple times. The Xfinity modem is currently in bridge mode.
If I take the xfinity modem out of bridge mode, I can access the xfinity wifi from any device so I know it is not a Concast/Xfinity issue.
Sounds strange. The first thing I'd try is to factory reset your whole network by deleting it from your Google Home home:
Then set it up from scratch, but reusing the old network name (SSID) and password, then your devices should reconnect automagically.
Make sure any VPN, also Apple iCloud Private Relay if on iPhone, is disabled during this process. If on iOS, make sure the Google Home app has been granted permission to "local network".
How big is your place? 5 pucks is a lot. Too many might degrade performance.
Do you have a switch in your network? Is it managed/ "smart"? That might cause trouble due to STP (spanning tree protocol), it must be disabled inside the switch if used with Nest Wifi.
I wanted to follow up and see if you are still in need of any help. Please let me know if you are still having any trouble from here, as I would be happy to take a closer look and assist you further.
Due to inactivity, I'll go ahead and lock this thread in 24 hours. Feel free to start a new thread if you need assistance with your Google Wifi and we'd be glad to assist you further.
