I have a Roku RC81. It used to work fine, but has now stopped working. I have changed the batteries and several other things that have been recommended but to no avail. Is RC81 still supported by Roku?
I don't know precisely which remote the RC81 is. What model Roku did it come with?
If it's an IR remote, you can test its functionality by viewing the end of the remote though a digital camera (such as a phone camera) and watch for a flashing light when you press a button on the remote. This won't work if it's a WiFi Direct remote working in that mode.

What is the Roku device you're using? Settings > System > About
Note that you should be able to use the Roku mobile app for Android or iOS to use temporarily. I would strongly suggest replacing the physical remote, but the one to get depends on your Roku model number.
