Hey
the use of iperf3 is very simple and does not require much study I will now go into the use via SSH - presumably the plug-in only takes care of the installation.
On the router
connect to your router via SSH (e.g. ssh root@192.168.177.1)
update the software database: opkg update
install iperf3: opkg install iperf3
start iperf3 in server mode: iperf3 -s
On any client, e.g. Windows:
Download iperf3: iPerf - Download iPerf3 and original iPerf pre-compiled binaries
Connec…
run iperf3 on the Mango, then you are testing throughput simply between the Mango and the wireless client running iperf3 to test throughput of the WiFi.
