Mi Router 4A

High-Speed Dual Band AC1200 Router

4 external antennas

64 MB memory for stable operation

Control remotely via app

Unauthorized access prevention

Parental Control


Enjoy a wireless dual band speed of 1167Mbps for a faster and smoother online experience

With 300Mbps over the 2.4GHz band and 867Mbps over the the crystal clear 5GHz band, the max wireless speed is up to 1167Mbps
The 2.4GHz band offers transmission over greater distances, with better coverage and better penetration through walls
The 5GHz band adopts 802.11ac technology
Less interference and higher speeds for a smoother experience watching HD videos and playing multiplayer online games

Smart Connect, once open tihis function in app, there’s no longer any confusion over which one to connect to

The Mi Router 4A supports Smart Connect, offering 2.4GHz and 5GHz bands under one Wi-Fi name
No more confusion over which Wi-Fi network to connect to 2.4GHz offers better performance through walls, while 5GHz provides higher speeds
The optimal frequency band is automatically selected by a dual-band terminal

4 external antennas

So that the signal can travel through walls better
4 external omnidirectional antennas, precision tested, and with a carefully designed internal structure and configuration
Greatly improves transmission performance, even in complex environments
Dual cooling fin heat sinks for better system stability
A specially treated metal substrate is combined with nanomaterials boasting exceptional thermal radiation features
Offers both excellent heat absorption and heat dissipation capabilities to effectively lower the chip temperature and provide improved system stability

Integrated signal amplifier, providing a good Wi-Fi signal and wide coverage

2.4GHz and 5GHz wireless chipset integrates PA and LNA
The PA (power amplifier) effectively strengthens the signal transmission power, while the LNA (low noise amplifier) can improve the sensitivity of the signal receiver
Allows the signal to be transmitted over greater distances, with better penetration through walls, and wider coverage

In the age of the smart home, having more connected devices requires a stable network connection

Mi Router 4A has a large 64MB memory
Ensures the stability of data transmission and stable connectivity of each access device
An intelligent error correction algorithm improves weak signals for more stable and efficient transmission
The 5GHz band supports the LDPC (low-density parity-check code) error correction algorithm to enhance anti-jamming capabilities during data transmission
Significantly enhanced Wi-Fi signal coverage for improved efficiency in data transmission

Easily manage the time children spend online and the content they access to make sure they are kept safe online

Effectively manage your family’s time online by setting the amount of time a device may be online, and the websites that can be accessed
Combined with the intelligent speed limit function, the speed of each access device can be limited to avoid network congestion caused by individual devices
Receive a phone alert when unauthorized users access your Wi-Fi, and block them instantly
When an unknown device uses the Wi-Fi signal without permission, the Mi WiFi app can send out a notification to inform the user that a new device has connected
If a suspicious device tries to join the network, depending on the security level, the device will be automatically blocked from connecting, or you will be prompted to block the device with one push of a button

Internet settings even the elder family members can handle

The internet settings are quick, easy and simple enough for even the elder family members to understand

Eco-friendly casing to protect the environment

Both the Mi Router 4A casing and packaging are made of recyclable and environmentally friendly materials that cut down on environmental damage so that we can protect our precious planet

Rigorous testing in the pursuit of excellence

Power stability tests

Over 220,000 test cycles

4 scenarios, cumulative number of 20 devices being powered on and off
