Enjoy a wireless dual band speed of 1167Mbps With 300Mbps over the 2.4GHz band and 867Mbps over 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.

Integrated signal amplifier 2.4GHz and 5GHz wireless chipset integrate PA and LNA. The PA (power amplifier) effectively strengthens the signal transmission power while the LNA (low noise amplifier) improves the sensitivity of the signal receiver — allowing the signal to be transmitted over greater distances with better penetration through walls and wider coverage.

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 enhancing Wi-Fi signal coverage for improved efficiency.

64MB Large Memory Smart home appliance era — more devices need a stable connection. Xiaomi Router 4A adopts 64MB memory that ensures stable transmission.

Control In your Hands When an unknown device uses the Wi-Fi signal without permission, the Mi WiFi app can send a notification to inform you a new device has connected. If a suspicious device tries to join the network, depending on the security level it will be automatically blocked or you will be prompted to block it with one push of a button.
