CM1100 Connects then disconnects with two amber lights on uplink

Thanks for the response. It's a coax I ran that is straight to the box a while back that I tried to make the dbmv as close to 0 as possible. The tech they sent out yesterday said the signal was one of the best he has seen. Showed me a graph showing the difference between each channel and it being a fairly straight line. We hooked my old modem up as a test and so far the old modem hasn't had any troubles. If it runs for another day or two without issue then guess I'll need to return this one.
