TP-Link Deco P9 Hybrid Mesh System


We have long dreamed of getting rid of wires – even the budget Smart TV now has a Wi-Fi module, not to mention office equipment and other electronics. Yes there is electronics – a kettle or a crock-pot may also require a high-quality connection.

If you live in a relatively small apartment, just put a router, connect an Ethernet cable to it – and you’re done.

If the apartment is large, it is likely that you will have to install a powerful router, because the usual signal may not be enough.

If you have a solid three-story cottage, then powerful models will not be able to provide good coverage in each room. The signal simply does not pass through thick walls – the quality of the connection and its speed drop.

When the repeater is small

In such cases, mesh systems come to the rescue – a set of several equivalent Wi-Fi modules (each can be a router or an additional access point). We have already tested such kits more than once – the connection parameters are really better than using only a router or it with a repeater. But to add several access points of a new type to the system is not the only option to improve communication. If your house has thick walls and with a complex configuration, such measures may not help.

Since high-quality Internet cannot be launched “over the air”, why not use wires, or rather an electric network? Any house already has electrical wiring, and this is the same physical connection between the rooms.

One of the technologies for providing communication through wiring is called Powerline. Adapters using this type of connection have been on the market for several years. But both wired and wireless communications have certain disadvantages. Therefore, it would be logical to combine the two connection methods in one mesh-system, providing it with additional stability.

Two in one

TP-Link Deco P9 is just one of these systems. It consists of two (or three, depending on the configuration) Wi-Fi modules, which are combined into a single seamless network using Wi-Fi, as well as by connecting to a power supply network.

Since the satellites are combined into one system, a seamless connection is ensured throughout the territory. That is, no reconnection and “falling off” of channels. Moreover, the modules are actually the same: each has two gigabit Ethernet ports for:

  • Internet connections,
  • connection modules
  • connecting customers.

The same with the settings: one module completely duplicates the other, the device is connected to the one whose signal is stronger.

TP-Link Deco P9: operates in two bands: 2.4 GHz (speeds up to 300 Mbit / s) and 5 GHz (up to 867 Mbit / s). A set of two devices can serve an area of up to 370 m2, of three – up to 560. Up to 100 client devices can be connected. It’s clear that bandwidth is limited, but if you have a good “input” channel, the system will have enough capabilities, for example, to watch streaming video on 8 devices with a resolution of 1080p.

All settings are made from the Deco mobile application. It has a fairly rich list of features. For example, you can manage the profile of each device: set parental controls for children and see which sites they go to, limit the time on the network for each device … Those who consider it necessary to turn off Wi-Fi at night can do this with the click of a button .

Of course, it is possible to create a guest network. This is relevant, for example, when organizing some events, even a banal birthday. In order not to give out the password to everyone (and we hope it is quite complicated), it is easier to create a guest network with free access for one day.

Stealth assistant

During the test, the system behaved stably, making it possible to maintain a speed of about 50 Mbit / s in a two-story house with an input channel throughput of 60 Mbit / s. True, it’s hard to say whether this is due to good Wi-Fi coverage or Powerline technology.

The only gripe with the devices themselves is the rather large size. For example, they may not fit on a shelf of a cabinet or table in height.


In recent years, there have been many more devices connected to the Internet in our homes. Now this is not only mobile gadgets, but also household appliances, security systems … For their full work, a good connection is necessary, and traditional routers are no longer able to provide it in a large house. Therefore, mesh-systems that were previously used mainly in offices, are becoming an attribute of large houses. TP-Link Deco P9 is the next step towards solving the problem of network deployment in large areas.
