reset chromecast after changing router

After buying a secondhand chromecast (which remembers the wifi from old home), or changing the router at home, it is necessary to reset the chromecast.

If you have already changed the router, you can not ask chromecast to forget the previous wifi, but it is OK.

  1. Connect phone to the new wifi.
  2. Open Google Home on the phone, delete device.
  3. Reset chromecast by pressing the reset button for 25 seconds.  Now, I found it necessary to unplug the power, and replug —- only after this step, the chromecast is showing white light.  When it was orange light, my phone could find it, but couldn’t connect to it.
  4. Set up a new device in Google Home app.  Follow the instruction on TV and in app.
