How to test cnPilot E400 Router Throughput

Products Enterprise Wi-Fi Networks

Hi,

the throughput of my clients connected to my cnPilot E400 (cnP) is comparably low in the 10Mbit/s range (see iperf3 test results below). I don't know if the problem is on the wireless side of things or if for some reason there is a problem in the wired connection between the cnP and the rest of the network.

The cnP is connected with a CAT6 cable to a Netgear GS110TP PoE smart switch (switch) that provides both network and PoE to the cnP. 

Is anything wrong or not recommended with this setup? I could also use the cnP's PoE injector, but I'd rather us the switch's PoE for a few reasons.

Both, the switch and the cnP show the link speed to be 1000Mbp/s. My internet provider's router shows the connection to the cnP as 10Mbit/s, though I am not sure how it determines that as it's not directly connected and I don't pay too much attention to that. It shows the same for a Raspberry Pi while I could confirm the Pi has 100Mbit/s in accordance with the Pi's specs. 

I test all connections between computers on my network using iperf3. Is there anything comparable I could use to test the connection of the router's LAN connection? 

Thanks,

Klaus

P.S.: Here is the perf3 output between a wire connected server and my client:

iperf Done.

 

When connecting my client to the switch I get pretty reasonable 950Mbit/s.

In the meantime I've changed one setting to disable 802.11w State as suggested in another discussion. If I am very close to the router with direct line of sight I can now get close to 100Mbit/s on 5GHz. Is that about the best I can expect, or are there any chances it may go closer to actual GB speeds? Could this still be a problem with the link between the cnP and the switch?

For reference, I get connection speeds of around 170Mbit/s on 5GHz with my provider's router through the basement ceiling. 

Thanks,

Klaus

Any updates on this?

can't we run speed test between ap and client using SpeedFlex tool. 

on ap enable Wi-Fi Perf under operations tab and client install SpeedFlex App (available for iOS and Andriod OS)
