I got a set of TP-Link Mesh Wi-Fi systems. TP-Link Deco X90, AX 6600 Tri-Band Mesh Wi-Fi 6 System.

Here I would like to show some basic information about it.

The box is big and heavy. Two nodes can cover 6000 sq. ft. or  557 square meters.

Some Features:

Compare the X90 with Linksys Velop. It is bigger and heavier.

Installation of the Deco X90

The very first step is to install the app from Google Play or AppStore.

Then, follow the on-screen directions. Step by Step to complete the first X90 device and later add the second one.

The default is to use Wi-Fi to connect the second X90 to the primary (the first) X90. I prefer to use ethernet to connect them.

I live in a three stories townhouse. I put the primary Deco X90 in my office, which is in the south of the building. The second X90 is in my daughter’s room, in the north of the building.

I have my own router, which is a soft router. I did not plan to replace it. So I use these two X90 as an Access Point.

Tp-link  Deco App and Features:

Deco App, and the first screen of it.

I named my network “deco6”, kind of boring.

Operation mode as Access Point

Touch the nine-dots icon, more settings, touch the Advanced, Operation Mode, then choose Access Point.  Because I connect the primary Deco X90 after my router.

Two Deco X90. One in my office. The second one is in Gloria’s room. It is only the wireless connections. I have more devices wired connection to the network.
The great features.

I like this one. The Deco Lab, Wi-Fi assistant. Test speed, port checker, etc.  A lot of fun features in this Deco Lab.

Web Interface

There is also a web interface for X90. I know their IP address of them from the Deco App. and 173. is the main Deco or Primary X90.

From my desktop, I enter the IP address into Google Chrome.  By entering the password of the TP-link ID, I can access it.

I can see the device CPU load, memory usage, and the clients who connect to my network.

At the Advanced panel, it shows the status and a lot of System-level functions, including firmware upgrade, system log, time settings, reboot, and system parameters. These are for all devices of this network.

When I enter into Google Chrome, the second Deco web interface. It is only shown me the System log, Firmware upgrade, and reboot. it is for this device only.

I am not using functions like NAT, Parental Controls, QoS, Connection Alerts, etc.


There is a small issue with the system. I am using AP mode, my mobile device can not get the IPv6 IP address through Deco X90 from the Router. Maybe the next firmware can solve it.

My Conclusion

The Tp-link Deco X90 provides great features and fast Wifi speed. I would like to recommend it to someone like me having a problem using one Wi-Fi Access Point in a townhouse or even a big house. Because It is very hard to place one single AP at the center of the house. Two X90 make a mesh network. It is easy to make it cover the whole home, from the basement to the third story.

I am going to make a wireless speed test later.
