The Roku 1 was released almost 7 years ago, so it's possible it's just failing. The remote is IR, so there's no pairing to worry about. Check the remote for functionality by looking at the emitter end through a smart phone camera. If you see flashing when pressing any remote button, the remote is fine. That only leaves the Roku. If there's nothing blocking the front of the Roku, so the IR signal can be seen, then it's likely just failing. Honestly, the new Roku players are so much better than your model 2710, you really should just consider replacing it.
