Internet Speed

Greetings - I am currently on the Gigabit X2 plan and am supposed to be getting 2100 down and 300 up.

Speed tests show that I am only getting on average 925 down. Up speed averages about 350 and is fine, no problems there.

Would like to get closer to the down speed that I am paying for. 

Any help would be greatly appreciated.

are you wireless or hard wired? If hard wired i believe you have to be plugged into the red jack on the back of the xb8 modem.

From the street to the house to the Xfinity CGM4981COM it is connected via coax. From the Xfinity equipment to my Synology RT2600ac it is connected via CAT6.

Confirming that the CAT6 cable needs to be connected to the red port on the back of the CGM4981COM?

... Gigabit X2 plan ... getting on average 925 down ...

What modem or gateway are you using, and are you connecting with Wifi or Ethernet? Are you using a standalone router?

If any of the devices in the chain are only capable of 1 Gbps you'll only see 940 Mbps or so due to protocol overhead.

Modem/Gateway is Xfinity CGM4981COM. The router it is connected to via ethernet cable is a Synology RT2600ac which is 2Gpbs capable.
