XIAOMI MI Router 4A, Gigabit Edition

Fibre-optic full-gigabit for high-speed broadband over 100 Mbps:

• The Mi Router 4A Gigabit Edition features one gigabit WAN port and 2 gigabit LAN ports, easily achieving network speeds of 100 Mbps and above. Compared with 100-megabit ports, this allows you better utilize every megabit of bandwidth.

Dual-core CPU for faster connection speeds:

• Features dual-core quad-threaded processors with a single-core clock speed of up to 880 MHz for powerful performance that easily supports gigabit network ports and gigabit dual-bandWi-Fi data transmission for a smoother online experience.

Wireless dual-band 1167 Mbps for faster and smoother internet connections:

• The dual concurrent bands, 2.4 GHz and 5 GHz, do not create interference, and offer wireless connection speeds of up to 1167 Mbps. The 2.4-GHz band transmits over greater distances for better coverage and better performance through walls; the 5-GHz band uses 802.11ac technology to reduce interference and boost connection speeds, for a smoother experience when watching HD videos and playing online games.

Dual-band integration with one Wi-Fi name eliminates confusion:

• The Mi Router 4A supports dual-band integration, combining the 2.4-GHz and 5-GHz bands under one Wi-Fi name. No more having to worry about which Wi-Fi to connect to 2.4-GHz band offers better transmission through walls, while the 5-GHz band delivers higher speeds.The dual-band device automatically selects the optimal frequency.


• The 4 precision-tested external omni-directional high-gain antennas have been carefully designed and arranged to maximize transmission performance, even in more complex environments

Integrated signal amplifier ensures good Wi-Fi signal over a wide coverage area:

• The 2.4-GHz and 5-GHz wireless chips each feature an integrated power amplifier (PA) and low noise amplifier (LNA). The PA effectively enhances signal transmission power, while the LNA improves signal reception sensitivity. This allows the signal to be transmitted over greater distances, better pass through walls and cover a wider area.

Large 128-MB memory supports stable connections for up to 128 devices:

• Smart Home Era Ensure a stable connection for each and every connected device

The smart error correction algorithm improves weak signals for greater stability and efficiency:

• The 5-GHz frequency band supports low-density parity code (LDPC) code to correct errors. This reduces interference during data transmission and significantly increases Wi-Fi signal coverage for more efficient data transmission.

Keep your kids safe online by managing the time they spend online and the content they see:

• You can set time limits for Internet access by specific devices and set which websites your children can visit, to protect them when they go online.

Receive instant notifications when someone accesses your network and block them in one step:

• The Mi WiFi app will notify you when an unfamiliar device connects to the network.

Internet settings that both parents can configure:

• Quick and easy Internet settings, simple enough for parents to use

Smart app offers remote control and a wide range of features:

• The Mi WiFi app includes useful features like Wi-Fi optimization and anti-hacking protection, and it lets you easily manage your router and any linked devices, so you can control them remotely from anywhere. Check out the MiWiFi app now to experience even more useful features.

Powerful cooling to guarantee safe operation at all times:

• The chassis employs broad-surface aluminium-magnesium alloy heat sinks and high-conductivity thermal paste and large vents on the bottom to effectively improve the cooling efficiency of the whole unit. The rear panel has added cooling vents to facilitate air flow. This conducts heat away from the internal components to the outside, ensuring the long-term reliable operation of the device.

Eco-friendly casing protects the environment:

• The outer casing and packaging of the Mi Router 4A Gigabit Edition are made of recyclable and environmentally friendly materials, reducing damage to the environment, so that we can protect our precious planet.


• Simply designed to blend easily into a variety of home styles:


• The router body has an understated geometric form and durable non-coated matte white plastic shell—simple and durable, aesthetically in harmony with the rest of your home.
