How to set up a Xiaomi 4 Pro router: from connectivity to fine optimization

Xiaomi Router 4 Pro is one of the most popular routers in the Xiaomi lineup, combining high performance, Wi-Fi 6 support and advanced network management features. However, even such a device requires the right setup to unlock the full potential, from stable coverage to protection from external attacks. In this article, we will analyze the step-by-step instructions – from basic connection to professional tricks for experienced users.

Many face typical problems: weak signal in distant rooms, spontaneous shutdowns of devices or low speed despite at a high-speed provider tariff. The reasons are not in the router itself, but in the wrong settings – whether it is an incorrectly selected Wi-Fi channel, outdated firmware or conflict. IP-We will show you how to avoid these mistakes and make the most of your Xiaomi Router 4 Pro.

Important: the instructions are relevant for MiWiFi firmware ROM version 2.0.100+ (2023–2026) If your router runs on old firmware, update it first through Settings. → Update the software, otherwise some functions may not be available.

1. Preparation for setting up: what to do before turning on the router

Before you connect the Xiaomi Router 4 Pro to the network, follow a few key steps.This will save time and prevent common mistakes such as conflict. IP with another router or unstable power.

• 🔌 Check the configuration: in the box should be a router, power supply (12V/1A), Ethernet cable and brief instructions. If you don't have a cable, use Cat. 5e higher.
• 📡 Determine the optimal location: the router should be in the center of the apartment, at a height of at least 1 meter from the floor. Avoid placing near microwaves, cordless phones or metal surfaces.
• 🔄 Turn off the old router (if it was): it will prevent DHCP-If you plan to use the Xiaomi Router 4 Pro in repeater mode, leave the main router on.
• 📱 Prepare a smartphone or PC: to set up you will need a device with Wi-Fi or Ethernet port and a browser (we recommend Chrome or Firefox).

If you connect the router to a fiber optic terminal (for example, from Rostelecom or Beeline), make sure that the router is connected to a fiber optic terminal. ONT-Bridge mode is enabled at the terminal, otherwise there will be problems with PPPoE authorization.

⚠️ Note: Do not use power supply from other devices! Xiaomi Router 4 Pro sensitive to stress: unstable power supply can damage ports LAN/WAN.

2. Basic setting: connection and login to the web interface

The initial setup process takes no more than 10 minutes, if you follow the algorithm, and we will look at two ways: through the Mi WiFi mobile application and through the web interface (for advanced users).

Method 1: Configure via the Mi WiFi app (recommended)

1. Download the Mi WiFi app from Google Play or the App Store.
2. Connect the router to power and wait until the indicator on the front panel starts flashing orange (setting mode).
3. In the app, click Add Device → Router and select Xiaomi Router 4 Pro.
4. Connect to the temporary network Xiaomi_XXXX (password is indicated on the router sticker).
5. Follow the instructions: Enter the network name (SSID), Password, type of Internet connection (for example, PPPoE for Rostelecom or Dynamic IP Beeline).

Method 2: Configure via web interface (192.168.31.1)

If the app is not available or you prefer manual control:

1. Connect the router to the PC / laptop via Ethernet cable (port) WAN → device).
2. Open your browser and enter 192.168.31.1 (or miwifi.com).
3. Log in with admin login and password with sticker (by default – admin or the last 8 characters) MAC-address).
4. In the Quick Configure section, specify the Internet connection parameters (see the table below).

After saving the settings, the router will restart. Wait until the indicator is blue (successful Internet connection) or yellow (no connection - check the provider's data).

3. Wi-Fi optimization: channel selection, bandwidth and Mesh network

By default, the Xiaomi Router 4 Pro uses automatic channel selection, but this is not always optimal - especially in apartment buildings where neighbours' networks create interference. Manually adjusting channels and bandwidth can increase speed by 30-50%.

How to Choose the Best Wi-Fi Channel

Use the WiFi Analyzer (Android) or NetSpot app (macOS/Windows), So we can scan the airwaves, and we can use the optimal channels for 2.4 GHz — 1, 6, 11 (They don't overlap. 5 Choose channels with minimal loading (for example, GHz, 36, 40, 44, 48).

In the router's web interface, go to Settings → Wi-Fi and install it:

• 📶 2.4 GHz: Channel 6 (if free), width 20 MHz (for maximum stability).
• 🚀 5 GHz: Channel 48 (or other free), width 80 MHz (for maximum speed).
• 🔒 Security: WPA2-PSK (or WPA3, If all devices support it).
• 📛 SSID: Hide the network – it does not increase security, but complicates the connection.

Mesh network setting (if there is a second Xiaomi router)

Xiaomi Router 4 Pro supports Mesh technology, which allows you to combine several routers into one network with automatic switching between them.

1. Connect the second router to the power and wait for its initialization.
2. In the Mi WiFi app, click Add Device → Mesh-network.
3. Follow the instructions: Routers sync automatically (may take up to 5 minutes).

⚠️ Note: In Mesh mode, both routers must run on the same firmware. If the software versions are different, the update will be performed automatically, but this may lead to a short-term network shutdown.

💡

If you have dual-band devices (smartphones, laptops), turn off the Smart Connect feature in the Wi-Fi router settings.It automatically switches devices between 2.4 GHz and 5 GHz, but sometimes does so suboptimally, leading to lags.

4. On your device (such as a smartphone) add a new one. VPN-connection.

If you use VPN access to local resources (for example, to the IP-In the case of cameras, change the standard port. PPTP (1723) on another router (e.g. 1725) settings, which will reduce the risk of port scanning by attackers.

💡

Even if your network is password protected, attackers can connect through vulnerabilities in firmware. Regularly update your router software and disable unnecessary services (for example, FTP Telnet).
