The two-pack system of the Deco M9 that I tested contains two identical nodes and covers homes of up to 4,500 square feet. Additional nodes that provide another 2,000 square feet of Wi-Fi coverage each are available for $179.99, and there’s a three-pack system due out in the near future.

The circular M9 nodes look identical to the nodes used with the Deco M5 system, but at 5.7 inches in diameter and 2.5 inches high, they are about 1 inch wider and 1 inch taller than the M5 nodes.

The M9 Plus nodes contain two gigabit LAN ports (one of which acts as the WAN port on the main router node), a power jack, a reset button, and a USB 2.0 port.

A tiny LED indicator on the top of the node glows yellow at startup, pulses blue when the node is ready for setup, is solid blue during setup, and is solid green when everything is up and running smoothly. A red light indicates an issue such as a lost internet connection.

Technical Specifications

On the technical side of things, the TP-Link Deco M9 Plus uses 802.11 AC wireless connectivity. That’s the latest and greatest Wi-Fi format, with bandwidth capabilities that put many wired connections to shame. Whether you’re currently using a massive Gigabit Internet connection or not, having 802.11 AC prepares you for speeds to come.

Over individual bands, wireless speeds reach 400Mbps on the 2.4GHz band, and 867Mbps for the 5GHz band. All in all, there are six Wi-Fi antennas, one Bluetooth antenna, and one ZigBee antenna within each Deco M9 Plus.

Those antennas help provide high-performance connectivity over roughly 4,500 square feet. At least, that’s what you get when you’re able to position two separate units in the Deco M9 Plus 2-pack. The M9 is also available in a 1-pack, which has all the same essential features but supports about half as much square footage.

Like many mesh routers have started to do, the TP-Link Deco M9 Plus has uses dedicated 5Ghz backhaul for your network traffic.

But unlike many mesh routers, additional backhaul throughput can be issued to unused Wi-Fi bands, depending on network demand. So as the backhaul needs of your network get bigger, the M9 adapts to ensure the performance of the network doesn’t start dropping into oblivion.

Why  Choose the TP-Link Deco M9 Plus?

Why  Choose the TP-Link Deco M9 Plus?

The TP-Link Deco M9 Plus certainly has style on its side. It looks nothing like most mesh routers, or indeed, like a router at all. If you like to keep a minimalistic aesthetic around the home, and you don’t want one more electronic box crowding up your room, you might be impressed with how well the M9 Plus can blend in. If you’re not, it’s still small enough to hide-away.

When you look at the performance of the hardware within the M9 Plus, it’s easy to be impressed. Ordinarily, one of the simplest ways to access your network settings involves typing in the IP address to your router directly into a browser.

And within an intentionally intimidating-looking window, you then make adjustments to your network. The Deco M9 Plus makes it easier, simpler, and less intimidating to manage your network.
