Peplink 580 does not attain full throughput on WAN port

I have a peplink balance 580 , even i set my WAN port with max speed 1000mbps , and i still couldn’t get a full internet speed from ISP , i only get 450mbps or below and my subscription is 800mbps

anyone have idea ?

What is the hardware revision of your unit?

If it is HW1 then the expected router throughput is 400Mbps (What is the Throughput for my Balance Hardware Revision?) which would explain it.

(The port speed is immaterial, it simply identifies the ethernet standard for the port, not the throughput capability of the router.)
