My motorola rng 150n went bad with constant on off recycling. Took unit to local comcast store and they gave me an arris rng 150n that was to perform like the motorola. However after install my Sony receiver does not identify multi channel decoding as it did before with the motorola unit. I'm not getting 5.1 surround sound. Setup gives mono. stereo and matrix choices for the arris. Am I missing something om the set up of the arris? How do I get my surround sound back?
Note: Cabling is the same as before with hdmi between the rng 150n and tv. TV has audio pass thru with optical cable to sony receiver. My aftv gives muli channel decode signal with a similar cable configuation.
When your connections are solid, the answer is yes.
The arris box has dolby digital plus written on it and was giving only stereo sound. After connection and reconnection of my hdmi cable surround sound finally kicked in. I'm blaming it on the remanufactured arris box they gave me and some bad elctrical contacts.
