Mesh network with older routers

[Astac]

Hi, I want to create mesh network with older routers.

I have this 3 routers on my network and each of them run separate WiFi network

 

My main router on which I installed OpenWrt: hhttps://www.tp-link.com/au/home-networking/wifi-router/tl-wr741nd/

Second router: https://www.tp-link.com/in/home-networking/wifi-router/tl-wr840n/

Third router: https://www.tp-link.com/eg/home-networking/dsl-modem-router/td-w8961nb/

 

I tried looking for some useful information's but haven't find anything, because of this I'm writing this here.

Is there way to create mash network with this routers?

I expect that probably not, but still want to try asking with slight hope.

What do you want to use this for? Switching these WiFis to the same SSID and password would allow seamless switching. No need for mesh, if you already have ethernet at each location.

 

OpenWrt does support 802.11s based mesh, if you can install it on the other routers as well.

Thanks, unfortunately 1 router doesn't support OpenWrt so I'll try renaming WiFis and hopefully it will work way I want.
