Performance

The real test of any networking hardware lies in how well it performs in a range of real-world scenarios. TP-Link’s Deco X55 delivers solid results across the board, especially in medium to large homes.

1. Speed and Throughput

The Deco X55 supports theoretical speeds up to 2402 Mbps on 5GHz and 574 Mbps on 2.4GHz. While actual speeds depend heavily on your internet service and layout of your home, users consistently report excellent performance—often reaching over 500 Mbps on compatible devices.

Test Condition	Average Download Speed
Close to main unit (5GHz)	480–520 Mbps
One wall away	410–460 Mbps
Across the house (Mesh)	350–400 Mbps
Backyard (far corner)	150–200 Mbps

These numbers are more than sufficient for 4K streaming, large downloads, and even multi-user gaming sessions.

2. Coverage

One of the key selling points of the Deco X55 is coverage up to 6,500 square feet in a 3-pack configuration. In practical testing, the system comfortably covers a 2–3 story home with strong, stable signal in every room—including previously troublesome areas like basements or garages. The mesh handoff between units is seamless, ensuring you stay connected as you move through your home.

3. Device Handling

With support for up to 150 connected devices, the X55 is well-suited to the demands of smart homes. Streaming on multiple TVs, Zoom meetings, security cameras, smart thermostats, and smart plugs all run without a hitch. Its AI-driven mesh technology optimizes traffic intelligently, prioritizing devices and adjusting to patterns over time.

4. Stability and Reliability

In daily use, the X55 proves highly stable for most users. However, a small percentage of customers report occasional disconnections or reboots, particularly under heavy loads or after months of use. Firmware updates appear to have addressed some of these issues, but this is worth noting if your household depends on ultra-high reliability.
