Chromecast setup is failing and Google Home can't find it
Chromecast setup fails when your phone and Chromecast are on different WiFi networks or the Google Home app is outdated. Make sure both are on the same WiFi, unplug the Chromecast for 30 seconds to restart it, and update the Google Home app.
Chromecast setup requires your phone and Chromecast on the same WiFi network, both devices powered on, and an updated Google Home app. When setup fails, it's a network mismatch, incorrect WiFi password, outdated app, or Chromecast not powered on. Testing the network connection first solves most issues.
- ✓Have your WiFi network name and password ready
- ✓Make sure the Chromecast is plugged in and powered on
- ✓Have the Google Home app downloaded on your phone
- ✓Make sure you're signed into your Google account on your phone

Skip, I just want a technicianCommon mistakes to avoid
- Being on a different WiFi band — phone on 5GHz while Chromecast is on 2.4GHz (same router, different bands)
- Not entering WiFi password correctly — passwords are case-sensitive and easy to mistype
- Assuming Chromecast is broken when it just needs a power reset or app update
- Not updating Google Home app before starting setup
