How to configure 802.11r with LUCI

I speak a little english,

I would like to configure the 802.11r standard on my access points ( I have 5 Access Point). However, I would like to know how to connect them together. With this version : Powered by LuCI openwrt-18.06 branch (git-19.170.32094-4d6d8bc) / OpenWrt 18.06.4 r7808-ef686b7292

Can you explain to me the different section of the image below?

Is it possible to roam with cable? It's better ?


Have a good day

Unless you have a very specific reason to divert from the defaults, that is indeed all you need to do on all participating APs.

The goal is not to lose the connection between each wi-fi terminal
But how do you connect with each other to do this?

Same subnet on all APs so you don’t have to acquire a new DHCP lease, mainly. Much past that, you don’t. You can speed the handover a little with 802.11r, but there still is a moment without connectivity for most clients. 802.11r can take that down from 2-3 seconds down to a second or less, but it is still there.
