in my home I have a specific setup as you can see in the schema below:
The sender of data is connected to my hEX S router via LAN and a Netgear switch.
If the receiver is also connected like this (LAN), I get transfer speeds of ~600 Mbits (even though it is a 1 Gbits network, but I can live with that, it seems the hEX S is the bottleneck here).
If the receiver is connected via WLAN, as shown in the schema, the transfer speed is only ~10 Mbits.
All clients, no matter if LAN or WLAN, can get internet speeds of ~75 Mbits (I have a 100 Mbits contract, but it is within the range of the line length etc.)
Could you guys please help me to identify the problem?
The obvious problem might be the 260GSP Switch, but as I said, the internet works fine and I am too much of an amateur to know which setting is worth checking out.
So many factors at play …
I assume it’s one flat network, no VLANs involved ?
HEX S might indeed be the limiting factor when doing LAN to LAN.
You can easily test this when testing using 2 ports on HEX S itself, you should get close to 950Mb then.
How do you test ? Using internal iperf3 server ?
I would first test using LAN to LAN on that bottom right AC Lite to see what you get there.
Then LAN to Wireless on the same device.
That will properly isolate wireless performance for that access point and then you can move from there.
Further on it might be needed to provide export of config for various building blocks, but let’s start first with testing only that AC Lite.
f the receiver is connected via WLAN, as shown in the schema, the transfer speed is only ~10 Mbits.
Wired connection speed is checked !? hAP ac Lite is 10/100Mbps ethernet ports. It negotiates with other side of the cable. What is the selected speed? What duplex half/full. What at the other side? Half/full mismatch in 100Mbps gives a performance drama !!! (eg when connecting 100Mbps full on one side with 100Mbps auto on the other side … auto will then select half, because full does not negotiate)
Idem exercise for the WLAN interface. What is the interface rate selected (in real time, it varies over time!)
2.4GHz usually should only be 20MHz wide on channel 1 6 or 11.
In the hAP ac Lite the 5GHz band is only single stream (1S) , most other AP’s have at least 2 streams/antenna for 5 GHz
See https://mcsindex.com or https://wlanprofessionals.com/mcs-table-and-how-to-use-it/
So with hAP ac Lite: 2.4GHz has max interface rate of 144.4Mbps, the 5GHz with 40MHz width gets 200Mbps
Net rate for ethernet is maybe 99% of interface rate, with WLAN wifi it gets lower with higher rates (too small transmissions with constant inter-transmission delays), eg 360Mbps is max for 866Mbps if-rate
