Okay, we tried a systematic test. 1) used Tv remote to change from cable to Roku. 2) pressed up down right left buttons on cable remote. It made beeps but no effect on screen. 3) used Roku remote to go to home screen. 4) repeated button pressing on cable remote, same result. 5) selected Netflix channel and started playing a program, using Roku remote. Went to Roku home screen. Used Tv remote to change input to cable, which tuned into a cable show. Pressed “guide” on cable remote. It changed input to Roku port.
Tried one more thing. After watching Roku (PBS channel) went to cable input and pressed off button on cable remote. That turned the TV off, as usual. Then used cable remote to turn tv on and cable remote worked normally. So that is a work around, tho not an acceptable one.
Any idea what is going on? Have you seen this with other Roku devices?
Unless you see a fix for it, I’m just gonna return this satanic contraption. Could you suggest what to buy instead? I’m in between the stick, which claims better WiFi reception, and the pricier Roku that has a Ethernet port so we could run a wire. We have an old house with lathe and plaster walls, so WiFi reception in our tv room is weak. Any advice appreciated. Thank you.
