CM1000v2 Slow upload speeds

I was wondering if anyone could help me out with my CM1000v2 modem. I am getting super slow upload speeds (2-5mbps when I pay for 50) and  my ISP is saying its my problem and they dont see any issues...

    ISP's fight not to come out. 

    Its their main goal in life is to make money off existing infrastructure without having to do maintenence on it. 

    You have errors (the codewords) and t3/t4 errors. They indicate a connection issue with the isp. 

    So if you're directly connected to the line coming in and you know that end connector is good, it doesn't leave much that could be the problems. It could always be the modem so thats the chance you take but the errors/logs indicate the line.
