A TP-Link Deco Mesh Wifi system will connect to your current router, in fact, it absolutely must be coupled with a router, modem, or internet cable already installed by an ISP (Internet Service Provider.)

The tricky part is actually connecting it your router, as it requires quite a few steps. But we’re going to break it down step-by-step, as well as talk about the other features a TP-Link Deco has, and just why you might want one.

How Does the TP-Link Deco Mesh Wifi System Work with my Router?

When you see phrases like “5,000 square foot coverage” and “flawless highspeed wireless internet”, it might seem clear what the Deco models are offering. However, how they make that happen is another story. If you want to understand just how the system will work in your home, we have the answers.

Different TP-Link Deco models offer a variety of specs, but they all work the same. The various extra routers that are supplied with the system can be placed around your home and they work together to form a net of coverage, ensuring no dead zones or problems with interference that a single router might struggle with.

The various models can improve speed, the number of allowed connectable devices and all the routers work on the same wireless network for your convenience.  Simple enough right? Now that you know how it works, you will want to make sure you choose the model that is right for you and your home.

How Do I Connect TP-Link Deco Mesh to an Existing Router?

Some users have expressed confusion on whether they have an existing router, modem, or 2-in-1 combination. While for the purpose of this article we are going to discuss how to connect to a router, it’s important to know that there are different sets of instructions for the various ISP devices. Make sure you are working with solely a router for these steps to work.

  • Ensure you set up the Deco with a different SSID (wireless network name) than your original Wifi network.
  • Turn of your router’s Wifi. Sometimes this task can be performed by plugging in a laptop or device directly into the router from which a settings menu will pop up where you can easily disable it. Or you may need to talk directly to your service provider.

While there are only two steps, this process can be slightly challenging for those of us who do not have an affinity for technology. Don’t be embarrassed to ask for help! Calling your service provider early in the transition could save a lot of unneeded frustration.
