CM1000 Xfinity issues
Internet keeps working then it stops working. Have multiple T3 time outs also have messages in the event log that are critical what should i do? How to fix issue?
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?
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.
