cm1000 and xfinity issues or just Docsis 3.1 issue?
Hello all. I upgraded to the Gigabit plan with Xfinity. I use my own Modem (Arris Surfboard 3.0). After realizing I needed a Docsis 3.1 I bought the Motorola MB8600 or whatever but it was 3.1. Comcast...
I am having the same set of issues with Comcast in Seattle area. Anyone know what I can do to debug why the CM1000 is so spotty? Every few days I lose all connectivity and have to reboot the modem. Downloaded latest patches. With previous modem the thing would work for months no issues. My wife is saying I paid out the nose for CM1000 and the thing is much worse than the 30$ Motorola we used in the past. Can't really argue with her.
To debug I wrote a program to periodically connect ever 15 seconds to a remote site and verify connectivity. Sure enough about every 1-2 days I lose all connectivity and it does not recover. Have to cold boot modem. The logging on the modem looks pretty shoddy, how can I debug this thing?
Just a follow up. Comcast came out and replaced my outdoor splitter and signal now is great and modem rock solid. So root cause was poor signal due to faulty old splitter.
