Hi,
Thanks for letting us know about the issue that you are experiencing.
If your remote does not have a pairing button, then it is a standard IR (infrared) remote. If your original remote connected over a wireless network, you would need an enhanced "point-anywhere" remote. What device were you trying to connect your remote to?
For more information regarding the types of remotes, please feel free to visit our support page What type of remote control does my Roku® device use?
Thanks,
Danny
