Bests & Worsts Reviews from Amazon

After weeks of back and forth, Comcast/Xfinity told me this modem is no longer supported on their network. Even though it meets all of the requirements, they claim there's something special about their network that this modem just doesn't like. I couldn't get a clear answer on what exactly. Purchase at your own risk. UPDATE: I got a clear answer from an actual network person; This modem does not offer 16 channels, and Comcast does not offer the full DOCSIS 3.0 spec speed per channel; this modem is limited to about 60mbps. You need to buy an expensive 16 up 4 down (aka 16x4) modem to get anything above those speeds, even with a modem that says it can do better.
