A simple Roku remote is an IR remote with no tv controls at all. You have wifi remote which is the only kind of remote a Roku stick accepts.
Do you have the long range wifi receiver attached to the stick plus? It's the short usb cable with the bump in the middle. It's what the remote communicates with, without it no remote control of the stick. It would still control your tv by IR commands directly.
