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

Image icon Config File CM 30.04 KB

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.

chnll width / modulation /modem file

Hi MESCANO1
I believe your using modulation profile 1, qpsk and your channel width is 1.6Mhz wide. that's about 1.7Mb shared bandwidth.
what's the upstream snr? if it's 21 and higher, use mod profile 2. channel width, possible to make it 3.2Mhz wide?
your modem profile has 0 for upstream burst, try 20000 and rest.
please post your results
