Xiaomi Redmi AX5400

2022 New Benchmark for High-end Routers

Mesh System | Wi-Fi 6 Plus | Work With Xiaomi App

160MHz Ultra Bandwidth

Double the speed

Compared with the traditional 80MHz, the transmission channel is doubled*, making the data transmission more smooth and rapid. At the same time, it supports 4x4 MU-MIMO technology, and multiple devices can transmit data at the same time without pressure. Downloading large-scale games or 4K high-definition movies will be much faster, no need to wait that long.

4K QAM makes it faster by 20%*

Next-Generation Technology, Come Now

The standard modulation of WiFi6 is 1024 QAM, and 4K QAM technology has a more powerful data throughput, which is expected to become the standard of next-generation WiFi technology.

*When used with terminals that support 4K QAM technology, the theoretical rate of the 5GHz band is 20% higher than that of the 1024 QAM technology. The actual rate will vary depending on the terminal and the environment.

Independent NPU, Data forwarding speed increased by 80%*

Ensure the strong output of the core

Using the new generation of Qualcomm router chipset, the NPU undertakes data forwarding and ensures that the CPU can focus on complex core computing. While improving the powerful computing power, it ensures the stable transmission of data and reduces packet loss and delay.

6-way High-performance Independent Signal Amplifier

6 high-gain antennas can enhance signal strength, increase signal coverage and improve the ability of the signal to pass through the walls in your house.

*The actual coverage effect depends on the placement of the router, the thickness of the wall, and other interference conditions.

Mesh networking, more Wifi coverage in the house

It can be networked with different models of Xiaomi/Redmi routers*, and the mesh network can be easily configured with one click. Whether it is a large apartment or a small office, it can achieve full coverage. From upstairs to downstairs, the mobile phone can be switched between multiple routers without feeling, and the video call does not stop.

*The terminal needs to support the 802.1k/v protocol, and the actual experience is related to the capabilities of the user terminal and the actual environment.

512MB large memory

Up to 248 devices can be stable online at the same time

Designed for multi-device families, it supports 248 devices online at the same time*. Whether it is mobile phones, computers, game consoles, and other game devices, or whole-house smart devices such as TVs and sweeping robots, they can be connected to the Internet stably and respond quickly.

WiFi password change synchronization

Automatic reconnection

After changing WiFi password of the router, the new password will be synchronized to each Xiaomi smart device* which is connected to this router, and the Xiaomi device will automatically connect to the router using the new password without resetting the network configuration one by one.

Xiaomi Easy Connect

Smart Networking

Open Mijia App

Click the “+” in the upper right corner to automatically discover Xiaomi smart devices that are not connected to the network*, click to network, no need to enter any password.

Mijia APP one-stop management

Open the smart life

Easy to manage the router with One App

Xiaomi mobile phone exclusive acceleration, reduce delay

Easy operation, stable output

The router can intelligently identify your Xiaomi / Redmi phone*, open the exclusive acceleration channel in the game scene, give priority to ensuring your network speed and stability, and significantly reduce the delay and lag of the game.

*This function requires the phone manager in the MIUI system to be upgraded to version 4.2.3 or above

Compatible with Multiple Game Accelerators

New users can receive NetEase UU Accelerator for 15 days trial and Youbangbang Accelerator for 110 days trial for PS, Xbox, Switch, and PC. Game accelerators can select high-quality game nodes to enjoy ultra-low latency and reduce packet loss.

*How to get it: Enter the Mijia APP and then the router management page to install the corresponding plug-in, and get the trial benefits on the “My” page in the plug-in.

*Each game acceleration benefit can only be claimed once per router, and NetEase UU accelerator is only available for newly registered users.


*5400 megabit is the unlimited rate specification level of the router, including the theoretical rate of 574Mbps in the 2.4GB band and 4804Mbps in the 5G band.

*Calculated compared to the theoretical rate of the WiFi6 5G band of 4x4 80MHz.

*When used with terminals that support 4K QAM technology, the theoretical rate of 5G frequency band is 20% higher than that of 1024 QAM technology, and the actual rate will vary depending on the terminal and the environment.

*Data forwarding speed improvement brought by hardware acceleration Data comparison before and after the Redmi router AX5400 turns on and off the NPU, the data comes from the Xiaomi experiment “Redmi router AX5400 test report”.

*The signal strength and theoretical coverage of the signal amplifier are compared with the Mi router 4A Gigabit version. The data comes from the “Signal Theoretical Coverage Report” by Xiaomi Lab.

*248 units are the comprehensive access value of 2.4G/5G/LAN under laboratory conditions.

*Password change synchronization only supports Xiaomi smart devices that have been connected to Xiaomi Changkuailian. For details, please refer to the device manual.

*The supported game devices are for reference only, please refer to the corresponding Accelerator Network instructions for details.

*It can be networked with the latest software version of Xiaomi router AX9000/AX6000/AX3600/AX3000/AX1800, Redmi router AX3000/AX1800/AX5/AX6/AX6S, Redmi gaming router AX5400, etc. The maximum number of connected devices in the entire Mesh network is 10 units, the operator-customized version does not support mixing with retail products for the time being.

*The product pictures on the above pages are for illustration only, the actual product may have slightly different effects, please refer to the actual product.

*One-click network distribution requires the device to support Xiaomi FunConnect, which is subject to the device manual. A Xiaomi smart device that is not connected to the network means that the device is in the initialization state. If the device has been connected to the network, it can be reset by itself. The specific reset method is subject to the device manual.
