All the system is hard wired. Cable from shield to modem is 15 meters but I don’t think it is a problem or linkable to a possible data flow decrease. Do you know any application capable to measure data speed between devices of a local network?
iperf3 will perform absolute testing in both directions.
It requires the server on the qnap and the client on the device being tested.
192.168.0.21 is my QNAP.
Run from the command line:

Hi,
I’ve installed iperf3 both on QNAP and Shield, but I’m afraid I haven’t set them properly. I don’t understand how to get results between QNAP server (192.168.178.5) and Shield client (192.168.178.31).
With the iPerf server running on the QNAP,
Get the Android Development SDK (which contains the ADB tool) and install it on your computer. You can also get the iperf3 client for your computer.
The commands to run the test are just as I show above.
iperf3 -c ip.addr.of.server (translation: iperf3 -client_mode iperf3.server.ip.addr)
-and-
iperf3 -c ip.addr.of.server -R (same but now test the reverse direction)
To run from the shield to the qnap
adb connect shield
adb shell
Now on the shield, use the same iperf commands as you would from any client.
