Losing connection to Chromecast during setup

Community Member

I just moved places and am trying to setup my Chromecast to a new wifi. The setup is good until it's time to connect to the wifi.

There will be a pop-up message that says that I've lost connection or that I can't communicate to the Chromecast.

I've already done a factory reset and tried unplugging the Chromecast, waiting, and plugging it back in. I know it's not the network because it's running fine on my other mobile devices. It's also connected to the wall outlet so there's no power issue. I've also stood right next to it during setup and I still get the same message.

It sounds like you've already tried some of these steps but including them in full. Let us know how you get on!

  1. Make sure your Chromecast is within 15 - 20 ft (4 - 6 m) of the Wi-Fi router. If you have a dual band router, try to set up your device on both the 2.4 GHz and 5 GHz bands.

  2. Make sure Wi-Fi and Bluetooth are both turned ON on your phone or tablet.

  3. Turn OFF mobile/cellular data.

  4. Reboot your router. Most routers just require that you unplug the power source and then plug it back in to reboot.

  5. Reboot Chromecast by removing the power cable, then reconnect it.

  6. Make sure you're using the latest version of the Google Home app, by checking your app store for any updates.

  7. Restart the Google Home app.

  • Android: Swipe up from the bottom, hold, then let go. Swipe up on the Google Home app.
  • iPhone/iPad: Swipe up from the bottom, hold, then let go. Swipe up on the Google Home app. On older devices with a home button, double-click the Home button, then swipe up on the Google Home app.
  • Turn Wi-Fi off and on again on your phone or tablet.
  • Reopen the Google Home app.

If none of the steps above help, factory reset your Chromecast and then retry setup. You may also want to try setup using a different phone or tablet, just to test, if you have one.

Thank you so much for the reply. I think it just comes down to having a weak wifi signal. The router is on the other side of the house. I didn't think this was an issue because I used to have it here and it used to work fine. Thank you again!
