31 instead of 32 down stream Channels on Docsis 3.1 Modem and low upstream power
I installed an Arris T25 modem a couple of weeks ago. I am only getting 31 downstream channels, but Arris says I should have 32 Channels. I also have low power on the upstream side. Arris says to tell Comcast and they will increase the power and channels. I called Comcast and they told me that they don't have the ability to change these. I know this is wrong, as I have dealt with this problem before, and Comcast has corrected it with no problem.
Any help is greatly appricated,
