Model: Deco M4  
Hardware Version:
Firmware Version: Latest

Hello all,

 

I’ve bought a 3-piece Deco M4 set to enhance the WiFi signal in my house. I have a TP-Link Archer C2300 which acts as my router and DHCP server. I just want to add the Deco M4 units as access points via Ethernet/UTP or WiFi (see the example at the bottom of the picture).

 

To install them, you need to use the Deco app and connect to a Deco unit. However, when I do this, I can only configure it as the main router/DHCP server. The app says: Connect your Deco M4 to your modem or, if you don’t have one, connect it to your router. But there’s nowhere I can configure it as an access point.

 

Am I doing something wrong, or am I overlooking something?

Connect Main Deco (first Deco unit you plan to power on and configure) to Archer router and proceed through initial Deco configuration. Your Main Deco will be configured in router mode. After done with initial configuration, switch your new Deco mesh to Access Point mode: https://community.tp-link.com/en/home/kb/detail/334

  @Alexandre. Thanks, Alexandre — it works! I can now access the advanced settings. It’s strange, though, that you first have to install it as the main router (even though you already have one) and can’t configure it as an access point right away.

 

Now I need to figure out how to make it work as a true access point with the same network name, without using a cable (so over WiFi), and with its DHCP server disabled. It’s very troublesome…angry

Main Deco must always be connected with Ethernet cable. Satellite Deco can connect wirelessly. DHCP service in Deco mesh should disable itself automatically when running in AP mode.
