- 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

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

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.

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.
