In order for your remote control to communicate with your Roku player, ensure the front of your player is clear of obstruction. If you are connecting wirelessly, your player should have close proximity to your wireless access point or router to receive a strong connection signal. Sometimes a wireless extender or booster can help increase your signal strength throughout your home.
Tip: To receive a stronger wireless signal, try moving or rotating your player into different positions. Even a few inches can help.
