Cable modem upstream problem
I installed a new cable modem today. I have been getting very slow upload speeds like 6 mb slow, I pay for 150 upload. I saw on someone else’s post that customer service had to be notified that I was switching modems in order to get proper service. I have my own netgear cm2000 modem if that’s important.
EDIT:
I checked in the router settings, there are no locked upstream channels. But downstream seems to have many locked and is as fast as expected

Hello @user_03ieje
Thank you for letting us know your current situation and equipment. We want to make sure you get the experience you are paying for. The Netgear CM2000 is a compatible Comcast device, but it is not on the Next Generation Speed Tier List https://www.xfinity.com/support/devices/#unauth for the higher upload speeds. You may want to take a look at a CM2500 or CM3000.
