Unboxing the TP-Link Deco X55: An All-inclusive Mesh Wi-Fi

Breaking the Seal: What’s Inside the TP-Link Deco X55 Package?

My first contact with the TP-Link Deco X55 was positive. The packaging is well-designed and secure, making you feel that the company has put thought into their customer’s unboxing experience. Upon opening the box, I found three identical mesh units designed to provide comprehensive coverage. Alongside these, there was an ethernet cable and three power adapters. A handy touch was that the power adapter is thin, so it won’t take up too much space on your power outlet. What wasn’t apparent from the packaging, however, was whether the ethernet cable provided supports cat5e or cat6 speeds.

Initial Impressions: Identical Triplets Offering Extensive Coverage

Each unit of the TP-Link Deco X55 boasts an impressive design, similar to the other Deco models I’ve had a chance to review. Should you decide to place one of these nodes in a visible area of your house, it would blend seamlessly into your home decor. The units are equipped with three ethernet ports, each supporting gigabit speeds. A unique feature is that all three units can act as routers. However, only the main one connected to your modem out of the box will serve that function. The other two function as access points, expanding your wi-Fi coverage.

Beneath the Layers: Understanding the Functional Configuration

Unlike some other mesh WiFi systems that have separate router and satellite units, the Deco X55 units are identical – all can serve as routers. In this set-up, only one will act as your main router, connecting to your modem and serving as the gateway for the other two. The other two units wirelessly connect to the main router, expanding your WiFi coverage across your chosen area. This setup is especially beneficial for large homes or spaces where a single router would struggle to provide full coverage.

Interpretation of TP-Link Deco AX3000 WiFi 6 Mesh System (Deco X55)

Tackling the Theory: What is a Mesh Wi-Fi Network and Why Does It Matter?

  • A Mesh Wi-Fi network consists of interconnected devices
  • Provides seamless network coverage and eliminates ‘dead zones’
  • Offers flexibility, scalability beyond traditional routers

If you’ve ever had the frustrating experience of losing your Wi-Fi connection while roaming around your house or workspace, then you’re in need of a mesh Wi-Fi network. But what exactly is this, and why is everyone talking about it? Let’s break it down.

Decoding Mesh Wi-Fi Network

A Mesh Wi-Fi network typically consists of multiple devices. In the case of TP-Link Deco X55, it’s an ensemble of three units. One of these units serves as the main router and is connected to your modem, replacing the existing one. The other two act as satellites or ‘nodes’, and they extend the reach of your Wi-Fi signal.

But here’s the kicker: these satellites aren’t simple range extenders that need to receive the main router signal before they can redistribute it. Oh no, these units are interconnected to form a mesh (hence the name) around your home or workspace, ensuring seamless network coverage.

How Does Mesh Wi-Fi Network Matter?

Imagine this. You’re on a video call while walking from your living room, across your house, to your home office. With a traditional router setup, your call might drop, or video quality could falter as you move farther away from the router. But under the caring ‘mesh’ of TP-Link Deco X55, the call doesn’t drop or become pixellated as you move around – as a matter of fact, you hardly notice any change.

The units ensure you are always connected to the nearest one and thus, get the best possible signal. As you move, you’re seamlessly handed over from one unit to another – much like using cellphone service while on the move.

Key Takeaway

This is the crucial role that a mesh Wi-Fi network plays – eliminating Wi-Fi ‘dead zones’. But beyond that, it offers a level of flexibility and scalability that traditional routers can’t match. It doesn’t matter whether it’s the size of your space, the layout, or even the number of devices that you have – a mesh network is geared up to handle it all.

And a system like the TP-Link Deco X55 is a prime example of this technology in action. But as with any tool or tech, your specific needs and settings play a considerable role in determining whether it’s the right fit for you. That’s something we’ll delve into more detail later, as we explore the range, speeds, and performance of the Deco X55.

Home Shield: Bolstering Network Protection and Parental Controls

One feature that particularly stands out is TP-Link’s Home Shield. Straight out of the box, this system comes equipped with network protection measures that prioritize your online safety. With threats becoming more robust and sophisticated, this feature is a welcome addition.

What really caught my eye, though, were the parental controls. It’s one thing to ensure you’re protected from malicious online elements; it’s another to make sure your kids are safe too. There’s an inherent peace of mind that comes with the Home Shield, ensuring your digital space remains under your control. However, from my experience, the settings here aren’t overly complex, and while that’s great for ease of use, I wish there were more options for those wanting a bit more detailed control.

Size and Aesthetics: Comparing Similarities and Differences with Deco X60

Upon first glance, the design of the Deco X55 is elegantly simple and rather similar to the Deco X60. The units are compact, which is a plus. It’s relatively unobtrusive and slots into any room without becoming an eyesore.

The essential difference was in the number of Ethernet ports – three on the Deco X55, all supporting gigabit speeds. These could be beneficial if you have a few wired devices. Comparatively, the X60 has fewer Ethernet ports. An essential point in favor of the X55 if you ask me.

In conclusion, the Deco X55 is a solid mesh Wi-Fi system, ticking all the standard boxes and then adding a few of its own. TP-Link’s Home Shield and the smart, compact design certainly bring a new level of utility and aesthetics to mesh Wi-Fi systems.

I’ve had my hands on the TP-Link Deco X55 for a couple of weeks and I must say, the overall experience has been pretty smooth. It’s been serving as my main system and throughout this time, I put it through all kinds of tests – from speed to range. Let’s dive into the specifics.

Two Weeks with the Deco X55: My Initial Verdict

My initial impressions? So far, so good. The Wi-Fi connection has been steady and I have not experienced any drop-outs or lag, which is always a good start when it comes to Wi-Fi devices. The device has a seamless switch mechanism, thanks to its mesh technology – hopping from room to room, the connection shifts from one unit to another without a blip which is frankly quite impressive.

Speed and Range Tests: Putting the Mesh System to the Ultimate Check

I pushed the Deco X55 to its limits with all kinds of speed and range tests. I wanted to create a comprehensive image of its capabilities in a real-world scenario. Thus, I used my iPhone 13 Pro Max for testing as a representative of Wi-Fi 6 devices, and for a measure of diversity, I also threw in the Pixel 6 Pro as a representative of Wi-Fi 6E devices.


First thing first, speed tests. As expected, when connected to Ethernet, the speeds peaked to what my Internet Service Provider (ISP) offers, a respect-worthy 940 Mbps download and 880 Mbps upload speed. As crucial as wired speeds are, it’s the wireless speeds which truly determine a Wi-Fi system’s worth and I must say, the Deco X55 did not disappoint.

It’s important to note that devices connected via Wi-Fi will always have a drop in speed when compared to an Ethernet connection due to the nature of wireless transmission. However, despite the reduction, my speed test results remained more than satisfactory for any tasks I needed to conduct on a Wi-Fi device.


Another essential aspect of a Wi-Fi system is its range. It needs to effectively cover the area you live or work in without any noticeable dead zones. I found the Deco X55 quite impressive in this domain as well. Despite being essentially a budget dual-band system, the range went up to a whopping 250 feet. It’s important to remember though that range could vary significantly based on the construction of your building and any potential obstructions.

Final Thoughts on Performance:

Whether it was conducting some online research on my laptop in the living room or streaming my favorite series in the bedroom, my experience with the Deco X55 remained consistently smooth. While it doesn’t offer the same level of performance as some high-end tri-band systems, when you factor in its price-point, it’s hard not to be impressed with what this unit can offer.

If there’s one thing I’ve learned from my time with mesh Wi-Fi systems, it’s that the set-up choices you make have a significant impact on your Wi-Fi speed. I put the TP-Link Deco X55 to the test, and as ever, the type of backhaul configuration, whether wired or wireless, made a pretty huge difference.

Understanding Backhaul

Before we delve into the results, it’s worth giving a brief overview of what backhaul means in this context. In simple terms, backhaul refers to the connection between the main router you’ve hooked up to your modem and the additional access points that increase your Wi-Fi coverage. Wired backhaul means that these devices are connected via Ethernet cables, while wireless backhaul refers to a wireless connection between your routers.

Wired vs. Wireless Backhaul: Speed Test Results

  • Wired Backhaul: With a wired backhaul set-up, the speed test results were quite impressive. I was able to experience close to my full internet speed on my devices. The Ethernet connection between the main router and the access points ensured a stable and high-speed connection. Every port on the Deco X55 supports Gigabit speeds, providing a robust and reliable connection.
  • Wireless Backhaul: When it came to the wireless backhaul, the speed I experienced was significantly less, usual for most dual-band systems I’ve tested. However, considering the Deco X55 is a budget-friendly Wi-Fi 6 mesh system, I must say the speeds were still decent. Of course, it didn’t beat a wired backhaul, but for most day-to-day activities, it was more than enough.

Finding the Right Backhaul for Your Needs

Ultimately, the backhaul configuration you choose will depend on your specific needs and conditions. If you demand the fastest speeds possible, wired backhaul should be your go-to. However, if you can’t run Ethernet cables around your home or simply desire a good connection for general browsing and streaming, wireless backhaul using the Deco X55 would suffice.

In conclusion, whether wired or wireless, the TP-Link Deco X55 does provide reliable connectivity, but your choice of backhaul will determine how fast your internet speeds will be. As always, consider what your home setup and needs are before making your decision.

  • Dual band system provides decent wireless performance

With this in-depth dive into the awesome TP-Link Deco X55, it all boils down to how you set it up. You see, one set-up might serve you just fine, but another could seriously ramp things up a notch. Here, I dissected the three distinct set-up configurations – single, wired backhaul, and wireless backhaul. I aptly named them Options 1, 3, and 4, respectively.

Single, Wired, Wireless Backhaul: Exploring Optimal Set-ups

When I first installed the X55, I started with Option 1 . It surprised me with ridiculously high speeds, especially with the Wi-Fi 6 device. Almost gigabit speeds from a single router? Seriously impressive.

Next up was the wired set-up – Option 3 . Formerly known as Wired Backhaul. Now, without geeking out too much, I found that there was virtually no difference in speeds between the router and the dedicated non-router when hooked up via ethernet. A strong testament to the efficacy of gigabit speed support.

Then, I switched things up by removing the ethernet cable and opting for Option 4 – Wireless Backhaul. This one was a bit of a curveball to put it lightly. The numbers I churned out paled in comparison to Options 1 and 3 due to the X55 being a dual band system. But considering its price range and the fact that it’s a dual band, those numbers weren’t too shabby.

Performance of the Deco X55 in Different Configuration Scenarios

Testing out all three options demonstrated how the presence or lack of a wired connection between the units can significantly impact performance. Whilst Option 3 gave me the full speeds I was after, Option 4 showed a decrease in numbers, highlighting that wired connections offer the most optimal networking experience. However, if a wired backhaul isn’t a viable option for you, the Option 4 setup still provided a decent internet connection that could help eliminate Wi-Fi dead zones in your living space.

To Sum It All Up

Choosing the best set-up configuration for you can drastically improve your Wi-Fi experience. Apparently, in my case, despite the dual band nature, the TP-Link Deco X55 offers pretty impressive performance in a variety of configurations. And when it comes down to it, if you want the best possible speeds regardless of the configuration model, a wired backhaul is your best bet. But, if that’s not possible, remember, this dual band still does a pretty fair job wirelessly, too.
