Can I use Deco with my existing router?

Deco can be used with an existing router. Here are two typical connection structures.

Topology 1:

Note: When Deco works in Router mode, it’s not suggested to connect more than 1 deco unit to the existing router directly, as it may cause a network loop.

When Deco works in Access Point mode, it’s no problem to connect more than 1 deco unit to the existing router directly.

Topology 2:             

Here are several frequently asked questions.

Q1: Can I set the Deco Wi-Fi name and password to be the same as my existing router?

When Deco works with an existing router, it is suggested to turn off the router's Wi-Fi network and use Deco's Wi-Fi network instead to minimize the wireless interference.

Q2: Can I connect Deco wirelessly to an existing router to extend my existing Wi-Fi network?

Deco doesn't support Repeater mode, only Router and Access Point modes are available.

In the Deco network, the main Deco must be wired to a modem, router, or an internet cable to get internet access. In other words, Deco cannot be set up to connect to an existing router wirelessly. However, the slave Deco can connect to the existing Deco network wirelessly.

Q3: Do I need to set up my existing router to bridge mode if my router is a combination of modem & router?

Deco works well with a modem router, however, it’s suggested to configure the modem router in bridge mode to avoid some technical problems, such as double NAT. 

If you need more help, it’s suggested to contact TP-Link support.
