How to set up Xiaomi modem: from connectivity to fine network settings

Xiaomi modems are not just Internet sharing devices, but full-fledged network hubs with advanced traffic management, parental control and support for Mesh networks. 4A Gigabit, Mi AIoT Router AX3600 or 4G-MiFi modem – require the right initial setup to unleash its potential.Without a competent configuration, you risk unstable connection, security vulnerabilities or limited speeds even at a 1Gbps tariff.

In this article, we’ll take a look at the whole process, from physical connectivity to hidden MiWiFi features that the manufacturer doesn’t advertise, how to avoid common bugs (like dual NAT on a cascade connection), what DNS settings will speed up site loading, and why Game Accelerator mode isn’t really always good for gamers. And if you have a Xiaomi Home-enabled modem, we’ll show you how to integrate it into the smart home ecosystem without losing performance.

1. Unpacking and physical connection of the modem

Before you turn on the Xiaomi modem in the socket, check the equipment.

• 🔌 Power supply (pay attention to the stress: 12V/1A or 12V/2A model-wise)
• 📡 Removable antennas (if it is a model with external antennas, for example, AX3600)
• 📄 Brief instruction in Chinese (Russian version is not usually available, but it is not a problem)
• 🔄 Patch cord RJ-45 (if not 4G-modem)

Connect the modem strictly in this sequence:

1. Insert the antennae (if they are removable) and tighten until you click.
2. Connect the power supply to the modem, but do not turn it on in the socket.

• 🔌 Manage the Internet with the voice assistant Alice or Google Assistant.
• 📊 See traffic statistics directly in Mi Home.
• 🔄 Automate Wi-Fi shutdown on schedule (e.g. overnight).

For IoT devices (smart sockets, sensors) it is recommended:

• 📶 Allocate a separate 2.4 GHz network for them (many IoT devices do not run on 5 GHz).
• 🔒 Disable Internet access for them (allow only local network) in the Firewall settings.
