Cameras Stopped Working After Changing Router Set-up

TerriN1 — Wed, 11 Mar 2026 22:44:12 GMT

I recently added an Eero Router to my system and everything works great EXCEPT my cameras. I believe these cameras were purchased in or around 2020.

I tried resetting with a paper clip and it blinks a blue light.

Things I have tried and combinations of:

1. Rebooting Router and Phone

2. Turning Bluetooth on and off and rebooting phone

3. Changing Router to 2.4 ghz

4. Putting phone into airplane mode

5. Removing all mesh system pods and just setting up near main router

6. Using Home App/Using Nest App

7. Connecting directly to computer with cable

8. Took cameras off App entirely

I am getting an NCO22 code from Home App and Nest App in Android phone and c309 -502 code when plugging into computer.

I feel like I've run out of ideas. It worked before it should work now. I just don't get it.

It depends on which specific cameras and doorbells you actually have. See the post below for details.

Note that, if you have 1st gen Google Nest Outdoor Cameras (NOT the IQ cameras), there is no reset button. For those cameras, your only options are to go to Settings > Home Info > Home Wi-Fi help to change your Wi-Fi settings or to factory reset your camera by removing your camera from the Google Nest app, but either of these actions have to be performed while you are still on your old Wi-Fi network and can still communicate with your cameras. If you were not able to do that, see this topic: https://support.google.com/googlenest/answer/9249728.

Thank you. There is a pin hole on the front of the camera which I assume is a reset, otherwise I'm not sure why it's there.

It sounds like I need to undo what I did and go back to my old wifi temporarily in order to fix the cameras. That's a little frustrating. I'll check out those links. Thank you! 🙂

I don't think those links apply to my situation. I did reuse my wifi settings for the new router and it didn't automatically connect. The other option, using my old wifi I believe isn't an option either because I've deleted both cameras from my account so there isn't anything anymore to reconnect. I guess I'll have to wait the 60 days to see whether the cameras reset themselves.

Ok so I have an outdoor wired nest IQ and the reset button is on the front...not that that helps me any. If you have any other ideas let me know. Thanks.

If you have an IQ camera, you SHOULD be able to perform a factory reset and then try to reinstall your camera in the Google Nest app (unless you previously "transferred" it to the Google Home app). (If you can perform a factory reset successfully, I don't think you'd have to wait 60 days to reinstall.) There is a factory reset link in those instructions by @David_K in the link that I provided.

It might also be possible that something else is going on to trigger the NC022 error you're getting, which is supposed to indicate there is a Bluetooth connection problem (https://support.google.com/googlenest/answer/9240048).

The factory reset doesn't seem to work and I'm continuing to get a Bluetooth error. I bought new cameras and they set up in 2 minutes. Although unlikely, is it possible that having an older phone might cause the problem? I've run out of ideas. If I wait the 30 to 60 days will they reset? I have 2 cameras and they are both the same...blink slow blue and I get noc22 error.

I don't think an older phone should make a difference unless it's so old you don't have the latest version of the Google Nest app and Google Home app.

If you're getting a blinking blue light, then it would seem that your factory reset was successful and your cameras are ready to be reinstalled.

I'm not sure what else to suggest about addressing your Bluetooth issue. Was the Troubleshooting link of any help?

I looked at those links but, as I've deleted the cameras from my account, my only option appears to be to wait the 60 days... but I don't get a message that it's connected to a different account just the Bluetooth message nco22 so I'm skeptical it's going to work.

@TerriN1

You could try doing a Google search for "nc022 bluetooth error installing google nest iq camera" and try the steps suggested there.

If you're getting a flashing blue status light, then I think your factory reset was successful, and the option of waiting up to 60 days just does not apply. Your cameras are factory reset; you just need to get past the Bluetooth error. What version of the Google Nest app do you have? (You can find the version by going to Settings | Account; the version is at the bottom. I'm on 5.86.3.)

I have tried searching that error and I also deleted and re installed the nest app. Tried both home and nest apps and it doesn't work. I'm giving up. Thanks for the suggestions though.
