Why Can’t I Cast Xfinity Stream?

A few requirements must be met to cast the Xfinity Stream application to a bigger screen.

Xfinity uses wireless Wi-Fi technology to detect and connect with devices on your local network, entirely wire-free and without extra equipment.

Here are the potential reasons why Xfinity Stream won’t let you cast content:

How to “Cast” In Xfinity Stream?

Follow these steps to set the “Cast” feature within the Xfinity Stream app:

1. Browse the available Xfinity Stream content for broadcasting.
2. Turn on a TV show or a movie you wish to cast on your TV.
3. Press the “Cast”  at the top-right next to the three dots icon.
4. Wait for the “Available Devices” list to open on your phone.
5. Select your Chromecast device when the unit is discovered.

Xfinity Stream Chromecast Not Working – 7 Proven Solutions!

1. Reboot Xfinity Stream & Device

The Xfinity app could have encountered a temporal functionality complication that prevented the “Cast” feature from working correctly.

To resolve any issues with the Xfinity app, you must close the platform and remove it from the temporal memory of your mobile device for a fresh startup!

Follow these steps to reboot Xfinity Stream and then restart your device:

1. Exit the Xfinity Stream app on your mobile device.
2. Access the temporal memory of your mobile phone.
3. Swipe up or down to remove the opened Xfinity app.
4. Then, hold the power button on the side of the phone.
5. Once the power menu appears, select the “Reboot.”
6. Wait until your mobile device restarts and turns on.

Note: When all services are refreshed, test to Chromecast from your Xfinity app!

2. Cast Alternative Xfinity Content

If the selected Xfinity Stream content isn’t applicable for casting or the resolution/aspect ratio settings are not configured correctly, it will not connect with the Chromecast.

The next step is casting several TV shows or movies to test if the issue is broadcast-related or setup-related.

Select any available on-demand Xfinity content and hit the “Cast” button! Feel free to test with as many different shows as possible.

So, make sure to attempt to cast, for example, different movies and not different episodes from the same show.

This will suggest if the issue is related to the selected service or if you are not able to cast anything from the app.

Note: Test to cast something that has worked before!

3. Reconnect the Chromecast Device

If the Chromecast device isn’t appearing in the “Cast” settings within the Xfinity app, chances are that the dongle has failed to establish Wi-Fi connectivity.

To restore the connection of the Chromecast, you must reconnect the device through the Google Home app.

Note: Only the 2nd generation Chromecast is compatible with 2.4GHz and 5GHz WiFi!

Follow these steps to reconnect the Chromecast device to WiFi:

1. Open the Google Home app on your mobile device.
2. Touch and hold the Chromecast device’s tile option.
3. Tap “Device Information” and navigate to “Wi-Fi.”
4. Tap “Forget this network” and wait for 5-6 seconds.

Tip: For the Wi-Fi connection to be secure, the Chromecast must be in a 15-20 meter radius of the network router device.

Follow these steps to soft-reset a network router in easy steps:

1. Locate the power button on the back of the router.
2. Then, press and hold the button for 10 seconds.
3. Wait until the network router powers off by itself.

5. Wait for 60 seconds while the router is unplugged.
