Wired Nest Doorbell NC006 error but the password is correct.

Community Member

My Doorbell was casting to my phone just fine but not the TV which it had done in the past. I decided a first step might be to delete and reinstall the wired Nest doorbell.

I removed it from the NEST app.

I did a factory reset. It did the countdown etc as described.

I updated the Nest app.

I have powered the doorbell and router off and restarted both.

The bell has a blue light as before. There is a good voltage at the doorbell. It chimes when pressed.

But after I enter the WIFI password as requested, after a delay it gives me an NC006 error which is saying wrong password. I have checked this many times and friends have logged on/off my WIFI with that password.

There is a strong WiFi signal at the bell. All is on 2.4GHz (not 5G) and the internet activity in the house is only this and some other unused tablets. (On, but not in use.) Also a home hub.

So, my first problem is to get past the NC006. THE PASSWORD IS CORRECT!

Help please.

Hi ss2016, 


Thanks for reaching out to us, and I'm sorry to hear about the situation. I want to check if you are still in need of any help. If so, please follow these steps: 


  1. Double check the password for your home’s Wi-Fi network. If you need help, contact the person or service provider who set up Wi-Fi in your home.
  2. Tap the Try again button. Re-enter your Wi-Fi information. When prompted, carefully enter the password for your Wi-Fi network.


Let us know how that works.

Zoe, thank you for your message. I do apologise, the ISP has agreed there was a problem with my router and corrected it by some sort of reset over the network. I can now view the font door on my Home Hub and pixel 6a.

I am not sure if it is your department but what I can not do is stream the front door to my Chromecast and onto my TV. It used to work and no longer does though I can cast from my phone to TV. They are all on the same network. I am far from alone with this problem but we get no help from your colleagues.

Any suggestions as to how to get that fixed.

Thanks for your help, Steve.
