Reliable cm1200 suddenly dropping on Comcast
I bought this modem a few years ago and it's been rock solid until the past week. I started noticing waiting icons as the internet seemed to have issues. In the early morning hours I get notices that...
Have the ISP take a look at the event logs. Something is happening there.
Might ask the ISP for a loaner modem or check into another modem of your own to see if issues continue or not. Hoping the CM1200 hasn't died all the way.
Yes. I had my previous docsis 3 modem handy to use. But when it wouldn't provision, that prompted me to call Comcast. The tech saw that the upload channels were empty indicating an issue upstream. He removed the line filters on the source at the pole and the CM1200 modem has been back to 100 percent. So the issue wasn't software but Comcast hardware.
Thx for the help.
Glad you got it working. Please mark your thread as solved so others will know.
Enjoy. 📡
