Upload speeds RS700 are slow when compared to etherneted laptop direct to cm3000

Slow upload speeds from rs700+cm3000

 

  • 2gbit down / 300mb up service plan i am contracted for
  • Comcast tech just left and did a meter-based speed test on the coax line.  the coax line tested at 2300~ down and 480~ upload.  This establishes that the coax is good for the speeds of my contracted plan
  • CM3000 directly connected to a laptop via USB-c to ethernet adaptor gets 980mb (the dongle only supports 1gbit connectivity), and the laptop via the same connection gets 150mb/s~ upload. (its a older laptop... and its a laptop but this establishes a soft control)
  • CM3000 connected to the multi gig port via cat6 to the rs700 test ran both from in the router and the nighthawk app.  Speed test yields solid downloads from 1900 - 2200 mbp/s.  however, the upstream hard walls at 75mbp/s up load this will fluctuate 73,72,75 etc... never past.

 

rs700 is running firmware : 

Firmware Version V1.0.7.86_2.0.82

cm300 is running firmware :

Firmware Version V5.01.02

  • What is brand and model# of USB C adapter and the laptop?

    Tried a different PC or laptop to compare results?

      The US dingle is not reliant as that performs better the the rs700 directly connected to the cm3000 useing the internal speed test to the router. Also all the devices on the Lan (Ethernet) reflect the same 75mbs upload that the rs700 is showing

        If Comcast confirms it delivers more than 300mbps for the upload on the cable, the CM3000 + RS700 should be able to get 300mbps upload speeds for the embedded speed test, or at least 150mbps same as the laptop with the USB dongle.

        I think we've done this test in our lab. I will check it. Thanks.
