If your router and LG TV are too far apart to provide a reliable connection, there are a few things you can try. Moving the router closer to your TV can help improve the signal and make it more reliable. You can also try using an ethernet cable to connect the two devices, as this will provide a stronger connection than WiFi. Finally, if you have a dual-band router, try switching the TV to the 2.4GHz WiFi channel as this is usually more reliable.
