Only getting download speeds of 13mbps, have gigabit modem and router

Hello, I have the 

ARRIS - SURFboard DOCSIS 3.0 Cable Modem - White

  • Model: SB6190

 

Which claims to be capable of 1.4Gbps 

 

Paired with the 

WZR-HP-G450H : AIRSTATION™ NFINITI™ HIGHPOWER GIGA WIRELESS-N ROUTER & ACCESS POINT

 

Which claims to be capable of 450mps. 

 

I am paying for your 1000mps per second plan, and I am getting nowhere near even the 450mps, how can I improve my internet speeds?

There's a difference between compatible with Xfinity (your modem is), capable of 1 Gig ( your modem is)and compatible with 1 Gig service ( your modem isn't). If it's not compatible with gig service it defaults to Performance speeds(which is what you're getting).
