Telus box not working properlyx

The router should have nothing to do with the issue you describe if you're having issues with the PVR itself. Unplugging the set top box is merely a reboot. A reset is something different and should only be done after talking with tech support.

It really sounds like a remote issue. Have your flat out replaced the batteries in the remote? If it's not batteries and there's a hardware issue with the remote, there's no real troubleshooting for that. It would need to be replaced. That is an easy process so if you haven't already, contact tech support.
