Speedtests on Sagemcom using wired ethernet speeds are crippled

I was able to work around this problem by connecting an ethernet cable to the WAN port on my router to a GL-SFT1200 travel router LAN port.  This saved me buying a router that supports WAN over wifi or a different cell gateway.

I am able to get the same speed with my router now as on wifi with the Sagecom which is about 450 mbps up and 15 mbps down.

The Sagemcom is set to 5GHz channel 36 with 80 MHz bandwidth using HINT.  I have the 2GHz radio off in the GL-SFT1200 and the Sagemcom.  The GL-SFT1200 is configured as a network extender.  My main router is set to channel 149 on 5GHz.  Having the primary router channel set to something much higher frequency than the Sagemcom prevents radio communication interference.
