Question about bandwidth usage

[Belmin]

Hello,

I have a question regarding the throughput on the Quantum Spark 1570 Appliance. The client had 630/180 speed from the ISP, after some time they requested from the ISP a new speed which is 730/190. The ISP changed the modem and after measuring on the modem the speed is as espected. But measuring on the checkpoint the speed is not even near the one on the modem. Does anyone have any ideas? I tried to disabling QoS, MTU set to 1500.

What version of firmware?
What is the connectivity method?
How precisely is the bandwidth being measured?
What blades are active on the gateway?
