Cannot add device to Google Home app

[Nickhannah]

We had ATT cut our Spectrum home Internet line and we're without Internet for a couple of weeks. After getting it back online and changing network name, we had to reconnect all WiFi devices in the home. Our Google Nest battery doorbell camera had been showing offline all this time. You cannot change wifi network information for these devices in the app, so I followed the instructions to factory reset the device and remove from the app. Upon attempting to add the device back to Google Home app, the app cannot find the device, even after scanning the QR code or by typing the code manually. It says that the device must be connected to the same wifi network, but I cannot find how to connect the device to WiFi separately from the app. What am I doing wrong?

In a new setup it should connected once you scan the device, did you remove the device from your home as well as factory reset it?  Instructions for your situation are below:

In the Home app, Wi-Fi information for cameras and doorbells can't be updated, so you'll need to factory reset your device and set it up again in the app. In most cases, you'll remove your device from the app and add it back.

Important: Make sure to save any important video clips before you start. When you remove your device from the app and factory reset it, you'll lose your video history.

Tip: If you set up your camera in the Home app (and it isn't compatible with the Nest app) and you want to keep your video history, don't remove your device from the app. Factory reset your device manually and set it up in the Home app as a new device. You'll have two versions of your device in the Home app, one with older video, and one with new video.
