If your Xiaomi TV F2 50 cannot watch online videos smoothly or the content buffers for too long, please refer to the following steps:
1. Make sure your TV is connected to a high-speed and stable Wi-Fi network. Check the Wi-Fi status by going to [Settings] >> [Network] >> select your Wi-Fi and press the [Play/Pause] button on your remote control. You can also use an Ethernet cable for a wired connection if possible, as it tends to be more stable;

2. Physical obstructions such as walls can affect the Wi-Fi signal strength. Consider relocating the router or using Wi-Fi range extenders if needed;
3. Power cycle your TV and router by turning them off and unplugging them for a minute. Then, plug them back in and turn them on;
4. If the video streaming service allows it, manually select a lower video quality (e.g., 720p) rather than the highest available quality (e.g., 4K) if you're experiencing buffering issues;
5. Try streaming content from different services to see if the problem is specific to one app or service;
6. Disconnect or limit the number of devices using your network simultaneously, especially bandwidth-heavy activities like large downloads or online gaming, which can affect streaming quality;
7. Clear cache and data by going to [Settings] >> [Applications] >> [Manage Installed Applications] >> select the app >> [Clear data] or [Clear cache];

8. Reinstall the app and see if the issue still persists. Go to [Apps] >> select [My Apps] >> select the app and press the three horizontal lines button on the remote control, select [Uninstall] and then reinstall the app;
9. Make sure your TV’s operating system is up-to-date by going to [Settings] >> [Device & Software] >> [About] >> [Install Update];
10. As a last resort, you can try performing a factory reset on your TV by going to [Settings] >> [Device & Software] >> [Reset to Factory Defaults]. Be aware that this will erase all your settings and data, so make sure to back up any important data before proceeding.
We hope the above methods can resolve the issue. If the issue still persists, you could submit your feedback on your TV by going to [Settings] >> [Help] >> [Send feedback], and follow the instructions on this interface.
