The Deco P9 is the cousin to the M9, which we reviewed earlier this year.
TP-Link’s P9 is a mesh system that can also double as a router. The system comes with three Deco units, three ac adapters, and a single Ethernet cable. There is also an option to get two Deco unit pack.
Deco uses mesh technology, which makes multiple devices look like one network changing to the fastest Deco as needed.

The setup process was quite smooth, and I didn’t have any issues this time over. It was as simple as following the on-screen instructions, thanks to the Deco App. Once the system is set up, up to 100 devices can be connected.
The additional P9s can be used to cover a larger area up to 550 square meters. The Deco has a feature called “PowerLine,” wherein your residences electrical wiring is used to eliminate weak signal areas.
The Deco app also allows for parental controls, which will enable you to block specific websites or monitor particular devices, which may help determine which method takes the most bandwidth. You can even see when new devices login to your network.
The Deco supports 802.11 ac/n/a on the 5 GHz band with speeds up to 867 Mbps. While 802.11 b/g/n 2.4 GHz with speeds up to 400 Mbps at 2.4 GHz.
While testing the Deco, we were able to get above 170 Mbps, which is my internet speed right now. Our test showed that the Decos speed was 1200 Mbps write &4100 Mbps read. Much higher than expected. These will be excellent speeds if you want to set up a home server.
