1167Mbps is the maximum theoretical wireless speed for 2.4GHz and 5GHz dual band concurrent Wi-Fi. Actual speeds will vary based on your environment

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 limi-
ted 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 automa-
tically 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!

Collaborations with authoritative international
test instrument manufacturers ensure router stability
In cooperation with authoritative international test instrument manufacturers such as Spirent and lxia, we conduct
large-scale tests simulating scenarios in the home and router performance under extreme conditions to ensure that the
router is able to operate stably under various conditions
The simple design sits easily in any home
The router body has an understated geometric form and durable non-coated-
matte white plastic shell which blends in with the home
