The TP-Link Home WiFi mesh also features a four colour LED signal indicator which shows the status of the Mesh router located under the TP-Link logo. The Status Indicators can be programmable to dim at night as well to avoid distraction while sleeping . All the 3 units which come in the Deco X20has 2 Ethernet ports and a power source to connect the adapter. If you are someone who likes to mount the device, it will be a disappointment for them. As this device does not have any mount hooks or any brackets can be added.

The TP-Link AX1800 has two antennae inbuilt in each unit to ensure optimal wireless coverage. Two Antennas has been used for each 2.4GHz and 5GHz bands. At the bottom, TP-Link Home WiFi Mesh has four bushes for grip on the flat surface and reset button placed under each unit. Which is useful for a reset when something goes wrong. The device features a larger heat sink inside which helps the Deco X20 to run a cooler temperature when its running 24×7.

The Wi-Fi AX band enabled Deco X20 delivers an overall good experience as a Home Mesh Wi-Fi system. With OFDMA and MU-MIMO technology, it offers to manage more than 150 devices simultaneous transmission to multiple devices. With the Wi-Fi 6, the device offers to support up to 1800 Mbps speed, 1201 Mbps on 5GHz band and 574 Mbps on 2.4 GHz band.

The Deco AX1800 supports the newer WPA3 WiFi encryption, which enables more secure and individualized security. The users on a WPA3-Personal network can’t ever snoop on another’s WPA3-Personal traffic, even when the user has the Wi-Fi password and is successfully connected.  Furthermore, if an outsider determines the password, it is not possible to passively observe an exchange and determine the session keys, providing forward secrecy of network traffic. Plus, they can’t decrypt any data captured prior to the cracking either. However, the compatibility of the WPA3 encryption could be an issue as the older device may not be supported.

The Deco X20 Home Mesh Wi-Fi AX router offers strong and reliable internet connectivity in our 1000 sq. ft 1 BHK apartment. In our testing, the WiFi speeds were consistent and there were no noticeable connection drops. In our 250Mbps line, we managed to get an excellent speed of 261 Mbps of downlink speed and 87 Mbps uplink speed. Unfortunately, since we did not have a connection higher than the device supported speed, we were unable to test the maximum speed delivery of the device.

The Mesh node placement is an important aspect to notice, as this will directly impact the performance of the device. The Fast Roaming feature on the device offers a seamless roaming performance with IEEE 802.11r support. This will allow the users to connect their wireless devices to the same access point and to switch connection to different nodes of the Deco X20 WiFi Mesh. This device delivers an exceptional user experience which an ideal WiFi mesh should deliver.


Like the TP-Link Tether App for the Extenders, the Deco App is intuitive and organized to manage the Home Wi-Fi Mesh system. It allows the users to manage the Deco X20 nodes right from their smartphone devices. The HomeCare features which are powered by TrendMicro, enables users to control the antivirus and all the security features including robust parental controls as well, which becomes handy to block the inappropriate content and limit the time which spends online. The App also allows users to update the firmware through the cloud-based Deco app.
