Frequently asked
My phone can't find the Chromecast during setup. What should I do?
Make sure your phone is on the same wifi you plan to use, and that Bluetooth and location services are enabled; restart the Google Home app and try again.
Should I use 2.4 GHz or 5 GHz wifi?
If your router uses separate names, try 2.4 GHz first; it can be more reliable during initial setup for some devices.
Will my purchased apps be lost after a reset?
Apps and purchases tied to your Google account remain, but the Chromecast loses all its settings and must be reconfigured.
Chromecast shows offline but TV has picture — why?
Reboot the router and Chromecast, then check in Google Home whether the device still uses the same wifi network.
