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

^{To enable this feature, you need to log into the web management interface}

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

^{This data comes from the integrated access extreme value in the Xiaomi laboratory environment}

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

• Wider coverage
• Intelligent error correction algorithm
• Anti-jamming for 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

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!
