Re: CM1000 Xfinity issues
T3 timeouts typically a issue with the ISP connection to the modem I suggest calling your ISP and have a tech come check your lines.

Re: CM1000 Xfinity issues
I'm also having connection issues. The log shows sync errors. Previous forums said to reset the modem with Xfinity and have it update the firmware to v3.01.04, which should have fixed the problem, however, I'm currently running V3.01.06 and it still cuts out from time to time. Very frustrating. I've enclosed my connection page. Any thoughts?

Re: CM1000 Xfinity issues
Your power levels are out of whack.
Downstream should be close to 0dBmV. 10-11 is dB is too high
your Upstream power levels way beyond spec and I am surprised it is even working with this power. You need to reduce the upstream power to mid-high 40s.
please call your ISP asap to fix your levels.
You can post it here on as well and people will say the same.
