Make sure that the batteries are a fresh pair and have the same brand as each other. Using two batteries with different brands can cause one to empty before the other, leading to the remote not working. Your remote may not be paired with your Roku device. Try re-pairing your remote by removing the battery cover and holding the pairing button until you see the pairing LED flash. If done correctly, a remote pairing notification should appear on your screen. For additional information and troubleshooting support, check out the Remote section of our troubleshooting guide.

If your network is a private network, make sure that the network password is correct. Try moving closer to the router or remove as many objects from the path of the router to the Roku. For a more in-depth troubleshooting guide, visit the WiFi section of our troubleshooting page.

Other people may be using your network. Heavy network traffic can cause everyone on the network to experience a slower connection. If you know someone else is streaming videos or downloading content, that would be the most likely cause of your low quality. Check out the Low Quality Videos section of our Roku 3 Troubleshooting guide to diagnose various connection issues. If internet speed or connection are not the issues, then the application’s servers may be under a heavy load.
