Case 1: If you have an unmanaged switch.

If you have an unmanaged switch, no settings need to be configured on the unmanaged switch. The switch is used to expand the Ethernet ports of the Deco, and after you wiring the Deco and switch, the main network and guest network will work properly.

Here are the two typical connection structures when working with the unmanaged switch.



Case 2. If you have a managed switch.

1. Please make sure that the version of your Deco App and firmware is up-to-date.

Please refer to FAQ below if you have any questions : How to Update the Firmware of Deco


2. In the topology below (Ethernet backhaul), you may find that you cannot have access to Internet via additional Deco’s guest network. This FAQ aims to teach you how to do the configuration on your switch so that the problem can be solved. Here we take the first topology (Daisy Chain Network) as an example. The main Deco is connected to port 1 and the additional Deco is connected to port 5.


Guest network


Main network and guest network are separated by VLAN. The guest network is tagged and main network is untagged. The VLAN ID for guest network is 591 by default. You can also set it between 3-1024.


Note: The VLAN ID button will only show up when your Decos are in Ethernet backhaul.

Thus you need to do some configuration on your switch. Here we take the TP-Link easy smart switch TL-SG105E as an example. Other switches work in the similar way.

The guest network and main network is separated by VLAN. The guest network is tagged and the main network is untagged. So you need to set two VLANs on the switch so that both of the network can work normally.

Step 1 Configure the VLAN setting of main network

You can set the VLAN ID as any number you want (not beyond your switch’s range). Here we assume that the VLAN ID of the main network as 2. And its Egress Rule is untagged. Click VLAN > 802.1Q VLAN. Enable 802.1Q VLAN Status. Set VLAN as 2 and VLAN Name as main. Then select the Untagged Ports:



Step 2 Configure the VLAN setting of guest network

The VLAN ID of Deco’s guest network is 591 by default and it is tagged. Thus here we take 591 as guest network’s VLAN ID. Repeat the steps as you do when you set the main network. Just note that you need to choose Tagged Ports here.



Step 3 Set PVID of the ports connected to your Decos

Set it the same as main network’s VLAN ID. Click VLAN > 802.1Q PVID Setting.



Till now all the configuration on your switch is done and just enjoy it!Please contact TP-Link support team if you have any further problems.
