If the three switches are the same, yes. While the Deco is in router mode the slaves will need to connect behind the main Deco so that works.

Hi.

Thank you for the advice.

Just to confirm.

Main Deco in router mode  +1 network switch attached.

Slave 1 +1 network switch attached.

Slave 2 +1 network switch attached.

No other physical connections.

This setup will work.

Any reason why does the 3 network switch has to be the same?

Thank you.

Lester

@LesterLee 

I see what you want to do, you are attaching switches to each Deco to expand the available ports. That will work, and the two slave Decos will connect to the main Deco via Wi-Fi. I thought you were going to wire everything together.

@Tony 

Thank you for the quick response.

Yes you are right.

The present situation does not allow me to run any more cables.

Thank you again,

Lester
