This one is probably the cheapest mesh network system available in the market. However, when it comes to performance and connecting lots of devices, and providing simultaneous coverage, customers seem quite happy with this router.

But, before you decide to pick this one, you should have a clear idea about what this router is all about. In the following sections, I’ll cover pretty much every aspect that will help you with your buying decision.

This package comes with three units, but you can purchase less or more than 3.

First thing first, the appearance. Each router of this mesh setup got a cylindrical housing with a tower form factor. The footprints are relatively narrower than its predecessor. So, from the space-saving perspective, Deco S4 leads the competition.

From the design aspect, these routers are quite smart-looking devices. Regardless of your room or house setup, these units will perfectly blend with the decor without any issue.

If your home workstation setup is themed in white color, then this system will add more to the aesthetics.


On paper, TP-Link claims the Wi-Fi network to cover up to 5,500 square feet with 3 units.

In reality, the coverage was as claimed. There was no dead zone in the house. And regardless of your house structure and shape, the system will provide a decent Wi-Fi coverage.

Customers reported that their devices connect seamlessly all across the house without compromising speeds at all. It even will extend to your yard a bit. You can roam with your smartphone around the house and still will be in the home network system.

Technically it can cover up to 8,000 square feet. But speeds won’t be as consistent as what you’ll get within 5,500 square feet.


Powered by a Qualcomm CPU, this router manages to provide consistent connection regardless of the number of connected devices.

Unfortunately, the chipset model name wasn’t found even on their official website.

Although the manufacturer claims it can handle up to 100 devices, there was no real test connecting this number of devices.

As for the antenna, TP-Link Deco S4 comes with dual band internal antennas. This is one of the areas that it lacks behind the latest M5 model.

Bandwidth Speeds

Separately, it’s 867 Mbps over 5 GHz and 300 Mbps over 2.4GHz band. Even though it’s relatively lower than the other one I’m comparing in this article, the difference won’t be much noticeable at all.

While connected to this router, multiple devices can enjoy full HD streaming as well as 4K videos without much issues. You won’t notice speed drop while downloading and streaming contents at the same time as per your internal plan.

While testing this Deco S4 for a whole home Wi-Fi network with 30 devices, including smartphones, laptops, desktops, iPads, IP cameras, and several smart home devices, it held up really well in terms of providing a great internet speeds and reliable wireless coverage.

You can pretty much roam around the house connecting your device with this router, and get seamless speeds and coverage under a single network name and password. This is one of the benefits of having a mesh system.

Your smartphone or other portable device will automatically switch between decos without even letting you know.

Unless typical Wi-Fi extenders or repeaters, no need to manually connect your device when you’re on the other end of the house.

For an easy setup process, there are both android and ios apps available for the Deco S4. You’ll have to follow simple screen instructions to set up the router in a few minutes.

But, there isn’t any web version of this setup procedure. That means, you can’t do it using your laptop.


There isn’t any mentionable security system for the TP-link deco S4 package.

However, you can use the parental control feature to monitor and limit the online activities of other devices connected to this system.

1. Robust Security

This is where the TP-Link Deco M5 router is far ahead of the Deco S4 model. Your devices will be protected from malicious websites that are listed in their database.
