Help Problem of not reaching nor 1Mb of Upload Cable modem in cmts c3 arris

Good morning

I have a problem, I tell you that my cable modems do not exceed 2Mb of upload, in the tests I do only show up to 20 Mb of download but upload only 512Kb and for more than try it does not rise even a Mb, then I will detail the configuration file of my cable modem to see if any opinion or someone who has gone through the same problem gives me their support.

I will attach the Image of my Config File that I am using for my aproving.
