The Xfinity Stream app allows Xfinity subscribers to stream live TV and On Demand content directly on LG Smart TVs. 

However, some LG Smart TV owners have reported issues with the Xfinity app not working properly on their TVs. 

If you are facing issues like the Xfinity app crashing on your LG Smart TV or the app freezing and buffering continuously, here at Smart Home Apt, we shall look into a few tips you can try to resolve the Xfinity app issues on LG Smart TV.



How to Fix Xfinity App Not Working on LG Smart TV ?

1. Ensure That Your LG TV Is Compatible With Xfinity Stream

If you have an LG Smart TV from 2018 or later, you can use the Xfinity Stream app. To determine the year of your TV, you can find it in the model number located in your TV's system menu or on a sticker on the back. For more information, please view the full process here.

If you have an LG TV manufactured before 2018, replacing it may be costly; a more cost-effective and simpler solution is to add a streaming stick.

You can easily access the Xfinity Stream app on any TV (smart or otherwise) by using a Fire TV Stick or a Roku streaming stick. Both of these streaming devices are simple to set up and come with all of the popular streaming apps.


2. Power cycle your LG Smart TV

App issues may be due to a random software glitch. The most effective way to fix this is to power off and then restart the device.

However, When you press the power button on your LG webOS TV, it won't actually reboot the device. Instead, it will enter standby mode, which allows it to turn on faster but can cause software bugs to accumulate over time.

Power cycling involves physically unplugging the TV from the power outlet for a few minutes. 

  • Press and hold the power button on the TV for 30 seconds after unplugging to discharge any remaining power. 
  • Then plug the TV back in and power it on.

Power cycling helps reset the TV hardware fully and can resolve app issues caused due to electrical fluctuations.

Now launch the Xfinity Stream app again. Restarting the TV can often fix technical issues. Keep these instructions in case you need them again in the future.


3. Test the Speed of Your Internet Connection

Xfinity Stream and other video streaming applications may be subject to buffering delays when using a slow internet connection. Severe cases may even prevent successful connection to the Xfinity Stream servers.

To check your internet speed, you can perform an Internet Speed Test on your computer or phone. Ensure that the device you are utilizing is connected to the same network as your TV. If you are using a phone, remember to switch off mobile data and connect only to Wi-Fi.

If your speeds are less than 3-4 Mbps for standard streaming and 5-8 Mbps for HD, you will need to take the below steps to improve it:

  • Examine sources of interference that may be causing disruption (e.g., too many walls between your router and your television). 
  • Reboot your router and modem (refer to the following tip). 
  • Reach out to your internet provider to determine if there are any issues with the network or if you need to upgrade.


4. Reboot your router and modem

Often, the issue resides with your local Wi-Fi network, rather than the TV or Xfinity Stream app.

Rather than attempting to troubleshoot every possible network issue, it is often simpler to simply restart your entire network. Doing this regularly (e.g. once a month) helps to ensure your network performs at its best.

Before beginning, confirm that no one in your household is currently using the internet. This process will temporarily disconnect all internet and network connections for approximately five minutes during the reboot.

Alright, let's begin.

  • Disconnect the power cord from your router and modem.
  • Allow 30 seconds to pass.
  • Reconnect the power cables.
  • Wait a few minutes for the modem and router to turn on.


If your TV is back on the network, try launching the Xfinity Stream app. If you previously did a test that indicated your network speeds were slow, run the test again now. Restarting your router can often increase your speeds temporarily, but it won't solve all issues.


5. Perform LG TV Firmware Update

Firmware updates can be just as helpful as app updates in resolving any issues you may be experiencing with your TV app.

LG smart TVs feature an auto-update functionality, however, it is possible to manually initiate a firmware update. Although this is not typically required, it is a useful option to have in the event that the automatic update is disabled or fails without notifying you.

To update your TV:

  • Press the Settings button on your remote.
  • Then go to All Settings and open the General tab. 
  • Select About this TV and click Check for updates
  • After the update is installed, power cycle your TV following the instructions given in this guide.


After updating the firmware, attempt to use the Xfinity Stream app again.


6. Remove and then install the Xfinity Stream App again

Reinstalling the app is an easier solution than manually clearing the cache on LG TV. Doing so will clear the app's data and may help fix the issues.

To get Xfinity Stream up and running again, you will have to uninstall the app and then install it again.


To delete the Xfinity Stream app:
  • Press the Home button on your remote control.
  • Find the Xfinity Stream app.
  • Press and hold its icon, click the trash bin icon above it.
  • Confirm by pressing Yes in the pop-up.


To reinstall the Xfinity Stream app on your LG TV:
  • Press the Home button on your remote.
  • Then navigate to the LG Content Store
  • Select the search icon in the top right corner of the screen and type in Xfinity Stream
  • Select the Xfinity Stream app from the search results.
  • Then press the Install button.


Attempt to use the Xfinity Stream app again and enter your log-in details, as they won't be preserved from the earlier installation.


7. Agree to LG's User Agreements

In order to utilize all of LG's features and apps, you must accept all of the license agreements.

Do the following:

  • Press the Settings button on your remote.
  • Navigate to All Settings.
  • Open the General tab.
  • Select About this TV.
  • Click on User Agreements
  • Ensure that Accept All has been selected.


8. Configure Your TV Location Settings

Most streaming services and certain streaming applications are geo-restricted, meaning they can only be accessed from certain locations within a country or across the globe.

Streaming apps such as Xfinity Stream may use various methods to verify your location. In some cases, they may use your LG TV's location setting to confirm your exact location. Therefore, it is important to ensure that your LG TV's location is correctly set.

Do the below:

  • Press the Settings button on your remote control.
  • Go to All Settings.
  • Open the General tab.
  • Select System.
  • Click Location and adjust the zip code to your current location if it is incorrect.


9. Turn Off VPN if applicable

Most video applications and streaming services attempt to restrict VPN traffic. If your VPN has been detected by Xfinity Stream, you may not be able to access your streaming content. To verify this, simply disable your VPN and try the connection again.


10. Try Xfinity Stream on a Different Device

Attempt to open Xfinity Stream on your computer or any other device connected to your network. 

If it works on the other devices but not your TV, reach out to LG support

However, if Xfinity Stream does not function on any of your devices, it is likely that the issue lies with your Xfinity Stream account or the Xfinity servers.


11. Find out the current status of the Xfinity Stream server

You can use Downdetector to see if other people in your region are having issues with Xfinity Stream. In most cases, Xfinity Stream outages are local and resolved quickly. Additionally, you can check the Xfinity status page for updates.

If you can't find anything on Downdetector, it's probably time to check Xfinity Stream Twitter support page for a more up-to-date information or you can Contact Xfinity Stream support directly.


12. Perform Factory Reset on Your LG TV

It's time to give one final attempt at resolving the issue: a factory reset. This will remove any personal settings and data for the Xfinity Stream app, including any TV settings. Despite the fact that this will erase all data, it may be the solution to the streaming app issues.

To reset your settings to the initial settings:

  • Press the Settings button on your remote.
  • Go to All Settings.
  • Select the General tab.
  • Click on Reset to Initial Settings
  • Confirm the action by clicking OK.

Try running the Xfinity Stream app again. This should resolve any software or firmware issues that were preventing the app from working on your LG TV.


In fact, there are several troubleshooting steps you can try if the Xfinity Stream app is not working properly on your LG Smart TV.  Start by rebooting your devices, ensuring your TV software and Xfinity gateway are up to date, and reinstalling the Xfinity Stream app. Also, Check that you have a strong Wi-Fi signal, or try using an Ethernet connection.  Finally, Clearing data and cache for the app, or performing a factory reset of your TV may also help.



Here are the 20 ways for fixing Xfinity App Not Working on LG Smart TV:


1. Restart your LG Smart TV and router - Restarting or power cycling your LG Smart TV and Wi-Fi router is the first step in troubleshooting connectivity issues. A restart can refresh network settings, renew IP addresses and fix any temporary software glitches. Unplug both devices for 2-3 minutes and power them back on.


2. Check your TV software is up to date - Outdated software or firmware on your LG Smart TV can sometimes cause streaming apps to malfunction or not work properly. Go to the Settings menu on your LG Smart TV and check if there are any available software or firmware updates for your TV model. Install any available updates and then try opening the Xfinity Stream app again.


3. Uninstall and reinstall the Xfinity Stream app - If the Xfinity Stream app is not working on your LG Smart TV, try deleting the app from your TV first and then reinstalling it. Go to the LG Content Store or App Store on your Smart TV and find the Xfinity Stream app. Select uninstall or delete to remove it. Then reinstall it from the same store and sign in again with your Xfinity ID. This will ensure you have the latest version of the app installed with no software glitches.


4. Sign out and sign in again - If you have signed in with an Xfinity ID to access content in the Xfinity Stream app, try signing out of the app within its settings menu and then signing in again. Signing out and back in with your Xfinity username and password helps to reset your authentication and connectivity with the Xfinity service. It will ensure your account information and credentials are being accessed properly within the app.


5. Check your Wi-Fi signal strength - A weak Wi-Fi signal can interfere with the performance of streaming apps like Xfinity Stream. On your LG Smart TV, check the Wi-Fi signal strength indicator to ensure you have at least 3 bars of coverage for stable streaming. If the signal is weak, try moving your Wi-Fi router closer to your TV or installing a Wi-Fi range extender. The Xfinity Stream app requires a fast, reliable Internet connection to function properly.


6. Restart your cable/Xfinity gateway - If you use an Xfinity cable gateway or modem to access Xfinity services, try restarting that gateway device. Unplug the Xfinity gateway for 2-3 minutes and then plug it back in. Restarting the gateway will reset your connectivity with the Xfinity network and can fix any temporary issues with the Xfinity Stream app recognizing your Xfinity service.


7. Clear data and cache on the Xfinity Stream app - In the settings or app info menu for the Xfinity Stream app on your LG Smart TV, look for an option to clear data and cache for the app. Select this to delete any stored data and free up resources for the app. Clearing data and cache for streaming apps can often fix software glitches and issues. After clearing, try opening the Xfinity Stream app again to test if it's working properly.


8. Try using an Ethernet connection - If possible, connect your LG Smart TV directly to your router or Xfinity gateway using an Ethernet cable. An Ethernet connection provides faster, more stable connectivity compared to Wi-Fi and may resolve any issues with the Xfinity Stream app. If the app works correctly with an Ethernet connection, the problem likely lies with your Wi-Fi network. You may need to improve your Wi-Fi coverage, change the Wi-Fi channel or update your router's firmware.


9. Contact Xfinity Support - If the above steps have not resolved problems with the Xfinity Stream app on your LG Smart TV, you may need to contact Xfinity customer support to report and troubleshoot the issue. They can check on the status of your Xfinity account and service to determine if there are any issues with your connection or subscription that could affect the Xfinity Stream app. They may also be able to push through a refresh signal to your Xfinity equipment or Walk you through additional advanced troubleshooting steps.


10. Disable screen saver or power saving mode on TV - Some LG Smart TVs can activate a screen saver or power saving mode automatically that disables network connectivity. This can cause streaming apps to stop functioning. Go to the Settings on your LG TV and disable any optional screen savers or power saving modes. Ensure your TV does not turn off network connectivity during periods of inactivity.


11. Reset your TV to factory defaults - As a last resort, you can try resetting your LG Smart TV to its original factory defaults. This will reset all settings, uninstall any apps and clear all data/cache to restore your TV to its out-of-the-box state. The option to reset your TV to factory defaults can usually be found in the System or General section of your LG TV's Settings menu. Once reset, you will need to set up your TV from scratch again and reinstall the Xfinity Stream app.


12. Renew your Xfinity ID - If you're still unable to access the Xfinity Stream app after trying the above steps, you may need to renew your Xfinity ID. Your Xfinity ID is used to authenticate access to the Xfinity Stream app and all Xfinity services. Occasionally, Xfinity IDs can expire or become invalid which will prevent streaming apps and services from functioning properly. You can renew your Xfinity ID on the Xfinity website or through the Xfinity My Account app. Sign in with your Xfinity username and password and look for an option to " Renew Xfinity ID ".


13. Troubleshoot issues with other streaming apps to determine if it's an isolated issue - Try using other streaming apps on your LG Smart TV to check if they are working properly. If multiple apps are not functioning, it indicates a general connectivity or software issue with your TV that is not limited to the Xfinity Stream app. You may need to perform a broader troubleshooting process, including restarting your TV and network equipment, ensuring system software is up to date, clearing app data/caches and potentially performing a factory reset of your LG Smart TV.


14. If other streaming apps are working fine but the Xfinity Stream app is isolated in not working - It usually points to an issue with your Xfinity account, authentication or subscription that you will need to troubleshoot directly with Xfinity Support. They can investigate issues specifically with your Xfinity Stream app access and make any necessary updates or changes to get the app functioning on your LG TV again.


15. Check for firmware updates for your router and gateway - Outdated router or gateway firmware can sometimes cause connectivity issues that affect streaming apps. Check if there are any firmware updates available for your Wi-Fi router and any network gateways like an Xfinity gateway. To update router firmware, you will usually log into your router's administration page using its default IP address. Look for an option to check for or update firmware. Follow instructions to install the latest firmware update.


16. Reset your router and gateway to default settings - If troubleshooting your network equipment does not resolve issues with the Xfinity Stream app, you can try resetting your router and Xfinity gateway back to their factory default settings. Resetting network equipment to defaults will erase any custom settings and restore standard out-of-the-box configurations. This can fix issues with Wi-Fi connectivity, firewall settings, device recognition and more.


17. Try rebooting other network equipment like network extenders -  If you use any other network equipment like Wi-Fi range extenders, Wi-Fi mesh systems, powerline adapters or network switches, try rebooting them as well. Other network devices can sometimes cause connectivity disruptions that affect streaming apps. Unplug each additional network device for 2-3 minutes and then plug them back in to power cycle them.


18. Try using a mobile hotspot to rule out home network issues - As a method of isolation, you can try using your mobile phone to provide a mobile hotspot connection for your LG Smart TV. If the Xfinity Stream app works correctly using your phone's mobile hotspot, it indicates there is likely an underlying issue with your home Wi-Fi network setup. Problems could include a malfunctioning router, gateway or extender, Wi-Fi interference, outdated firmware or an internet connectivity issue.


19. Try restricting bandwidth for other connected devices - If you have multiple connected devices using your home internet network simultaneously, they can compete for bandwidth and affect streaming on your LG TV. You can try restricting bandwidth for other devices to allocate more to your TV. In your router's administration page, look for QoS or bandwidth shaping controls. Select your LG TV and move it to "high priority". Then move other devices like computers, tablets, gaming consoles and streaming media players to "normal" or "low" priority.


20. Check if the Xfinity Stream app needs to be updated on your LG TV model - LG frequently updates the apps on their Smart TVs, including the Xfinity Stream app. An outdated version of the Xfinity Stream app may not function properly or support the latest features. In the LG Content Store or App Store on your LG TV, find the Xfinity Stream app and check if there is an available update. If so, select to install the update.
