TP-LINK Archer C20 and MESH

Hello! I would like to ask about the TP-Link Archer C20 V5 router. Could you please tell me if it is possible to create a full-fledged wireless mesh network with all the necessary functions (access points and internet access) using this device? Maybe someone has already set up a similar network using this equipment. If so, could you share your experience and let me know if everything worked as expected and if there were any problems during the setup process? Thank you very much for your help!

By and large, I need to set up a network similar to the one shown in the diagram.

That is, regardless of the location of the nodes in the mesh network, clients should always have access to the internet and the local network through the main gateway. At the moment, I have a Keenetic Peak.

If you have any other examples of routers (preferably affordable ones) that can be used to create a similar mesh network, please share the information with me. Thank you very much for your help.

glinet and cudy are cheap and fast cpu. You have to tell where you are and what is "cheap".

What distances you are trying to cover? <20m - optimize AP placement
Guest network? -YES - use batman
Mix wired and wireless links? - YES - batman
Otherwise 11s or batman fits the bill.

Keenetic Peak is not among supported, open a question in developers section, try to document whats inside etc, 1% chance it is clone of existing device YMMV

EDIT: archer C20 is very slow CPU-wise, but on the other hand you still can browse at other end.
