The LG 43-inch Class 4K Smart UHD TV w/AI ThinQ® (42.5'' Diag), Model # 43UM7300AUE is buffering because either your internet connection is too slow to stream a video in real-time, or the speed at which your router sends the video to all your internet-connected devices is too slow. You will need to upgrade your router. Often the problem with buffering is your internet speed. It is not unusual to not get the speed you pay for. You can easily be paying for 100 down but only getting a fraction of that speed. Sometimes your ISP can have damage on their lines running to your house, so run a speed test to make sure you are getting the speed you are paying for. Even if your internet speed is ok, weak Wi-Fi is a common issue that causes buffering. A weak Wi-Fi signal can cause slow speeds that lead to constant buffering. Look to see if the Wi-Fi signal on your streaming player is weak. Try moving your Wi-Fi router closer to your TV. Next, look at a more powerful router or even one of the new mesh routers. Finally, some users have had success with range extenders or using an Ethernet power jack to hard wire their streaming player. If your Wi-Fi keeps dropping or you are still having Wi-Fi issues in one part of your house, consider looking into getting a new router that has a Wi-Fi AC standard. You will see a huge improvement going to AC from the old N standard. Also, if you have an older or cheaper Wi-Fi router, it may not be designed to handle all the devices on your network. Not all routers are made to handle the same load...^Ivan
