Maybe I do need roaming for the routers. Both in Lsn. and at home. Maybe, it’s good just as it is.

Here’s the YouTube video that explains some details. But I’m still not sure whether I want that to be enabled. I found the video on the OpenWrt Forum.

iperf3

I think I’ll test with iperf3. From Arch Wiki’s Documentation on Benchmarking.

iperf is an easy to use point-to-point bandwidth testing tool that can use either TCP or UDP. It has nicely formatted output and a parallel test mode.

I need to start iperf server on my MacBook Pro, and (I think) preferably to connect it via LAN cable to the main router. Then I can test it on my iPhone.

tldr iperf3

Traffic generator for testing network bandwidth. More information: https://iperf.fr.

Run iperf3 as a server:

iperf3 -s

Run an iperf3 server on a specific port:

iperf3 -s -p port

Start bandwidth test:

iperf3 -c server

Run iperf3 in multiple parallel streams:

iperf3 -c server -P streams

Reverse direction of the test. Server sends data to the client:

iperf3 -c server -R

Still, I’d need to understand whether I need that roaming option or not.
