Can't connect to WiFi

[Raven3]

Hello, I'm hoping someone can help me. We had severe lighting and our broadband provider had to give us a new modem, it's identical to the one we had. Normally I could watch catch up on my TV from an app on my phone through chromecast. Now on my TV screen it says Can't connect to WiFi. Can someone advise please.

If you have a new modem, you need to give the Chromecast your new Wifi information.

1. Open the Google Home app.
2. At the top left, tap Add + > Set up device > New device > set up new devices in your home.
3. Follow the in-app steps.

If these steps above don’t solve the issue, you’ll need to factory reset your Chromecast, then set it up again using your new Wi-Fi network and password. If you're using Chromecast with Google TV, follow these setup steps instead.

Instead of factory resetting your Chromecast, if you're comfortable changing your router settings, you can change your new Wi-Fi network name and password in your router's settings to be the same as the previous ones. Your device should then automatically connect to the Wi-Fi.
