- The Chromecast device is within 15 - 20 ft of the mobile device or tablet you're using to set it up.
If you've checked off all of the steps above and you still can't connect to the Chromecast hotspot, try one of the steps below and then try to connect.

- Swipe up on the app's preview to close it.
From an Android device:
- Launch the Recent Applications menu to see small previews of your recently used apps.
- The Recent Apps button should be accessible at nearly any time along the bottom of the screen along with the other buttons on the virtual task bar.
Step 3. Try to manually connecting to the Google Chromecast SSID from your phone or tablet's Wi-Fi settings
- Go to the Wi-Fi settings on your mobile device.
- Open the list of available Wi-Fi networks and look for an available network with the name "ChromecastXXXX (where XXXX is a random number).
