Here's how to test your internet connection speed:

• Amazon Fire TV: On your Amazon Fire TV, go to Settings > Network. Then, press the Play button on your remote to check your network status. You can also download an Internet speed test app from the Amazon Appstore and test your connection speed (or test your speed from a computer on the same network. To do this, open a browser on your computer and search for 'internet speed test').
• Apple TV: On your Apple TV, download an internet speed test app to test your connection speed (or test your speed from a computer on the same network. To do this, open a browser on your computer and search for 'internet speed test').
• Roku: Press the Home button on your Roku remote, then go to Settings > Network > Check connection. To improve your wireless signal, see Improve your wireless Roku connection.

You need a minimum download speed of 5 Mbps to stream HD video. If videos are buffering, try reducing activity on your network.

Amazon Fire TV or Apple TV: Make sure you have the latest version of CNN. To do this, open the app store on your device and search for 'CNN.' If there's an app update available, download the update.

Roku: Make sure you have the latest version of CNN. To do this, press the Home button on your Roku remote, then navigate to the CNN app. Press the star (*) button on your remote, and then Check for updates. If there’s an app update available, download the update.

If other people are using the same network, ask them to temporarily pause their activity. This will allocate as much bandwidth as possible for streaming CNN.

Restart your streaming device and network devices. Here's how:

1. Turn off or unplug the device with CNN.
2. Unplug the power from your network devices (modem, router, etc.).
3. Wait 30 seconds.
4. Reconnect the power to your modem and wait for it to connect to the internet (about a minute).
5. Reconnect the power to your router and wait for it to connect to the internet.
6. Turn on the device with CNN and try streaming again.

Try streaming CNN on another supported device connected to the same network. This will help determine if the problem is related to your network or a specific device.

For the best performance, try connecting your streaming device to your router using an Ethernet cable (instead of using a wireless connection).

Make sure the cables to your network devices (modem, router, etc.) are all tightly connected at both connection points. A loose coaxial or Ethernet cable can weaken the signal.

Test your internet connection to make sure you have a minimum download speed of 5 Mbps. To do this, open a browser and search for 'internet speed test.' If your download speed doesn't meet the minimum, contact your internet provider to troubleshoot your connection speed.

Make sure you're using a supported browser.

If your browser is supported, update your browser to the latest version. To find out how to do this, search the internet for "update" + the name of your browser (i.e. update Chrome).

Try using a different supported browser. If videos play successfully with a different browser, check your browser configuration:

• Make sure third-party cookies are enabled.
• Disable ad-blocking software.
• Turn off private browsing or incognito mode.
• Disable browser plug-ins, extensions, and add-ons.

Close and reopen your browser, and then try streaming again.
