Wired setup

[SirLouen]

Can you can explain how have you wired your Tendas?

I'm currently using this method:

But I don't like it because everything has to go through the Tenda device regardless if it acting as a NAT or bridged with DHCP off as you put in your study.

I would like to set all Tendas, including the "primary node" all coming from one switch. Maybe all connected directly the LAN port and not using the WAN port at all is an option?

I am assuming you have looked here:

It sounds like you just want basic APs, maybe you could set up every one by itself under a different account and put it into bridge mode if you don't want to use mesh?

Seems like you need just APs and not mesh routers.
