Can't reach full bandwidth

Technical Support for Routers

Hi, I've had the Flint 2 for about a month now, I've noticed that in speedtests and iperf3 I can't get all the bandwidth on a single device, even if it's the only one connected.
It is connected to LAN2(2.5G) via Ethernet cat7 cable, with simultaneous iperf3 on 4 instances I got to 2.31 Gbps while with single instance I don't get to 1.9 Gbps.
Is this a software limitation? Is there any setting I can change? The same computer on other routers did 2.4 Gbps.

Thanks!

A single instance is not referenceable.
The 4 instances can run to 2.31Gbps which is a reference.

Iperf3 wireless speed test compatibility is poor, and the speed can be tested by building OpenSpeedtest.

The following topology is the best, NAT offload will work:

Laptop with OpenSpeedtest server <---> [2.5G WAN] --- Flint 2 --- LAN/WLAN <---> Laptop with OpenSpeedtest WEB page.

Thank you, but I did the test via cable.

OpenSpeedtest results are: 206,22/402,61.
Ookla Speedtest results are: 1911/477

Hello,

Does the OpenSpeedtest server itself have speed limits?

If iperf3 with 4 instances got to 2.31 Gbps, means the network port is normal and there seems to be no limitation.

Please try to switch to Software Acceleration, Auto, or disable the Network Acceleration.
