Design and Setup

One of the first things you’ll notice about the Deco X55 is its sleek, modern design. The white, cylindrical units are compact and unobtrusive, blending seamlessly into any home decor. You can place them on shelves, tables, or even mount them on the wall for optimal coverage.

Setting up the Deco X55 is a breeze thanks to the intuitive Deco app. Simply download the app, create an account, and follow the step-by-step instructions. The app will guide you through placing the Deco units, connecting them to your modem, and configuring your network settings. The entire process takes just minutes, and you don’t need any technical expertise.


Of course, the real test of any mesh Wi-Fi system is its performance. To assess the Deco X55’s capabilities, we conducted a series of speed tests at various distances and compared the results to popular competitors such as Netgear OrbiEero, and Google Nest Wifi.

In our tests, the Deco X55 consistently delivered impressive speeds throughout the house. Even in rooms furthest from the main unit, we saw download speeds well over 500 Mbps – more than enough for 4K streaming, online gaming, and other bandwidth-intensive tasks. The mesh network remained stable and reliable, with no noticeable drops or dead zones.

When stacked up against competitors like Orbi and Eero, the Deco X55 held its own. While the Orbi system offered slightly faster speeds in some scenarios, the difference was minimal, and the X55’s lower price point makes it a compelling alternative.

Comparisons and Alternatives

When shopping for a mesh Wi-Fi system, it’s important to consider your specific needs and budget. The TP-Link Deco X55 excels in terms of performance, features, and value, making it a top choice for most homes.

However, there are situations where an alternative might be a better fit:

  • For smaller homes or apartments, a cheaper dual-band system like the Deco M5 could suffice.
  • For users who demand the absolute fastest speeds and have a higher budget, the tri-band Netgear Orbi RBK852 or the Deco X90 with Wi-Fi 6E might be worth considering.
  • For those who prioritize simplicity over advanced features, the Google Nest Wifi offers an even more streamlined setup and management experience.

It’s also worth noting that Wi-Fi extenders can be a cheaper alternative to mesh systems for improving coverage in specific areas. However, extenders often result in slower speeds and less seamless roaming compared to a true mesh network like the Deco X55.
