R6900 : Slow Wired Internet Speed Compared to Modem

[JoeVA]

Using the latest R6900 firmware, V1.0.1.46_10.0.29, I ran a Comcast speed test using a Mac Pro (10.13.4).  If I attach the laptop to an ethernet port (Gigabit) on the R6900, I measure

110Mbps down, 5.6 Mbps up.

If I attach the laptop directly to the Comcast modem, I get 

250 Mbps down, 10.0 Mbps up.

Is there anything I can change in the  R6900 configuration to increase network bandwidth?

 I found a solution to in another post - disabling QOS increased the wired ethernet bandwidth to 197.0Mbps down, 11.7 Mbps up.
