I purchased a 4-pack AC1200 mesh system (gen 2? no reset button) from Costco and was able to install 3 of the units with no problem. I was unable to connect the 4th, so I assumed something was wrong with it and bought another single access point. The results have been the same- unable to get it to connect to the network. How should I go about trouble shooting to get this fourth (and now fifth) unit connected to the network? I tried placing in next to the wired access point, tried wiring it to that main access point with no results.
What do you mean by 'unable to connect', can you give more detail?
Have you tried doing a factory reset on the points that won't connect? https://support.google.com/googlenest/answer/6246619?hl=en-AU
And given you just bought them I'd suggest getting onto Nest wifi support, they're usually very helpful: https://support.google.com/googlenest/gethelp
No, you can just reset the single point that's playing up. I believe they all have reset buttons somewhere, as per here: https://support.google.com/googlenest/answer/6246619
So you discover the device in Google Home, but during setup it says it can't be added?
I was able to identify the reset button next to the QR code. I reset all devices and was able to connect each device while sitting next to each other, then deployed each to their permanent location. Thank you for your help.
