Upload Speeds maxed at 41mbps

I know this has been discussed many many times, but I'm bringing this up once again as I'm about to move to another provider.

I'm using a Hitron Coda56 modem and have been capped at 41mbps upload on a 1100mbps plan. This is becoming really frustrating as my security cameras need a good upload bandwidth and this impacts all other clients on my network.

Is there any way to fix this?
