Introduction

Are you having issues streaming your favorite shows or downloading your favorite movies using Xfinity internet or the Xfinity Stream app? Slow downloads, intermittent connections, buffering, playback issues, and errors can happen for many reasons. That could be a hardware or software issue, or an internet connectivity problem. Thankfully, you can resolve most connection problems with basic troubleshooting steps and checking your account status. Whether you're having trouble with your internet connectivity or the Stream app, this guide will walk you through common solutions that may help restore your service and improve streaming performance.

Check Your Internet Connection

The first step in fixing your download or streaming issue is to check if you still have an active internet service with Xfinity. You can do this by checking your modem or router and whether they have green non-flashing lights. You may also sign in to your account to check whether your service is still active. If you wish to speak to a representative and inquire about your service, feel free to also call Xfinity's 1-800 number.

If you have no internet connection at all but your Xfinity service appears to be active, check whether there’s an outage in your area. Temporary service outages may affect streaming, downloads, and overall internet connectivity. If your service is active but downloads are still slow, or streaming problems continue, proceed to the next troubleshooting step.

How Do I Fix Streaming or Download Problems with Comcast? (Step 1)

Restart Your Device

Device or system issues may also affect your internet connectivity, but these problems can often be resolved by restarting your modem, router, phone, or computer. Turn off your modem or router and wait about 10 seconds before turning it back on. Then, wait for the indicator lights to become solid and stable before testing your connection again. It’s also a good idea to restart your mobile phone, computer, smart TV, or streaming device.

If you’re using a streaming app like Netflix or Disney+, try closing and reopening the app first. If streaming problems continue, consider uninstalling and reinstalling the app to help improve performance.

Reinstall Xfinity Stream App

Are you using the Xfinity Stream app? If the app isn’t responding properly, check whether updates are available and make sure you’re using the latest version on your device. You can also try signing out of the app and signing back in to see if that resolves the issue.

Were you watching a program at home and trying to continue watching it through the app? If the content was recorded through cloud DVR, keep in mind that recordings may only become available online after the recording has fully completed. The same may apply to certain live TV content as well. If streaming or internet problems continue after troubleshooting, consider contacting Xfinity Customer Support for further assistance.

Conclusion

Are you using your own modem? If you just signed up for Xfinity service, do make sure that the modem or router you're using is compatible with Xfinity. If not, you may want to consider getting an upgrade to improve your internet connection. Connectivity issues such as slow speeds, intermittent connections, and playback errors can also be resolved by restarting your devices and applications. If the problem continues after troubleshooting, there may be an outage, account issue, or device compatibility problem affecting the service.

Why does GetHuman Write How-to Guides for Comcast Problems?

GetHuman has been working for over 10 years on sourcing information about big organizations like Comcast in order to help customers resolve customer service issues faster. We started with contact information and fastest ways to reach a human at big companies. Particularly ones with slow or complicated IVR or phone menu systems. Or companies that have self-serve help forums instead of a customer service department. From there, we realized that consumers still needed more detailed help solving the most common problems, so we expanded to this set of guides, which grows every day. And if you spot any issues with our What do I do if my Xfinity TV or internet is out? guide, please let us know by sending us feedback. We want to be as helpful as possible. If you appreciated this guide, please share it with your favorite people. Our free information and tools is powered by you, the customer. The more people that use it, the better it gets.
