Roku not waking

My Roku will not wake from screen saver when I switch to it. I have disabled the screen saver but does not help. Opens the remote but no control of the device. am using ip control by the way. Only way I get it to work is by going into edit mode and tapping the device in edit device screen. Should I assign a fixed address or is there another solution?

Yes, that’s exactly what happens when it changes IP and isn’t setup per the FAQ:

Thank you.
