Top Methods to Use Chromecast Without WiFi
1. Create a WiFi hotspot with your mobile (Android/iPhone)
The most universal solution is to take advantage of the option of share Internet or portable WiFi hotspot from your smartphone. The procedure involves having two devices:
- A mobile phone will serve as access point (Hotspot)This will be the “WiFi” that the Chromecast will connect to.
- A second mobile phone, tablet or computer for set up and control Chromecast and broadcast the content.

- Set the SSID (network name) and password. If you want to avoid having to reconfigure your Chromecast, use the same name and password as your regular home Wi-Fi network to which it's already connected.
- Activate the network and leave your phone near the TV for a better signal.
- With the second device, connect it to that access point and launch the app Google Home.
- When prompted, select Add/Set Up New Device and follow the on-screen steps to link your Chromecast to that “new Wi-Fi network.”

This trick is especially effective on Android devices, where you have complete control over the hotspot name. On iPhone, you'll need to change the phone name from Settings > General > About to do this.

If you have a laptop and you don't have Internet but you do have access to an Ethernet cable, you can create an ad hoc wireless network from your computer:
- On Windows, go to Network Center > Set up a new network > Ad Hoc Wireless Network, or use software like Connectify Hotspot to turn your PC into a virtual Wi-Fi router.
- On a Mac, go to Apple menu > System Preferences > Sharing > Personal Hotspot.
