Without an internet connection, you can’t use the Chromecast for casting and streaming purposes. An active internet connection is always needed for Chromecast. When you set up the Chromecast for the first time, you will connect the device to a WiFi network. Chromecast will think that the WiFi network is your Home network and will connect automatically to the WiFi network. When you changed your WiFi network password or username, you need to connect your Chromecast to the new WiFi network manually.

As the Chromecast is a portable device, there may be situations that you need to connect the device to a different WiFi network. If that’s the case, follow this guide to connect your Chromecast device to a new WiFi network.
