Nighthawk cm1200 speed

I am not sure if I’m understanding modem speed correctly. Xfinity says I have 1054 mps coming into the house but when I run a speed test on my new nighthawk cm1200 which is supposed to handle up to 2000, but my speed test on a hardline is only 550?

Be sure that LAG is disabled for testing speeds.

Re: Nighthawk cm1200 speed

Is this a wired speed test with a wired PC connected directly to the back of the CM modem? 

Is there a wifi router in between the CM modem and you wired test PC? 

 

Max input would be 1G at the input or Coax line, however on the WAN Ports each WAN port could support up to 1Gb at each WAN port that can be assigned by the ISP for each port. So technically, you'll only need near 900mbps or up to 1000Mbps due to the connection rate on each WAN port is 1000Mpbs max.
