Hello everyone!

I'm trying to figure out what is wifi mesh exactly and can't really find answers.

I'm wondering if it's a real tech or just a nomination, example: if I'm setting up multiple old wifi routers on the same local network with DHCP turned off (except on the main of course) and just put the same SSID and passphrase on all of them: could we call it a mesh wifi or does the technology really add something to it?

I made my parents buy some TP-LINK Deco wifi mesh routers for their property ^(which I regret now because openwrt is not compatible but that's a other story) and I don't really see any difference from them and the basic wifi repeater(cable) I've put in a last dead zone.
