Slow upload Speed RBR750

Hello Everyone, 

I have a question and I can't get it done in the right way. 

Model Version: ORBI RBR750
Firmware: latest V4.6.9.11
Environment: Orbi as modem and router, fiber connection 1gbps 

When I removed the modem from my supplier everything works fine but the upload speed is very slow. I have a 850 (almost max) download speed through the cable and 150 (1/6 of the max) upload speed. 

I saw some solutions to update to the latest firmware version but it is still not good. Anyone else with the same problem? I saw some posts on reddit as well about the same issue but no solution unfortunately. 

Can anyone help me?

    Try increasing the MTU size. Setting can be found on the web GUI under >> ADVANCED >> Setup >> WAN Setup
