How to configure Xiaomi 4 router via computer: a complete guide from connectivity to fine optimization

The Xiaomi Router 4 is one of the most popular network devices in the Xiaomi lineup, combining affordable price, stable operation and extensive customization options. However, many users face difficulties in the initial configuration, especially if they try to do this through a computer rather than a mobile application Mi Wi-Fi. In this article, we will discuss all the steps from physical connection to fine network optimization using only a Windows PC or macOS.

The main advantage of setting up via computer is more flexible control over network parameters, the ability to use advanced features (for example, SSH or Telnet for power users), and the ease of working with a large screen. But there are also nuances: some features in the Xiaomi web interface are hidden or require additional manipulation, we will show how to circumvent these restrictions and configure the router as efficiently as possible.

Preparation for the setup: what will be needed

• 📝 Data from the provider: connection type (PPPoE, DHCP, Static IP), login and password (if required).

If you don’t know the type of connection or you have forgotten the login details, contact your ISP’s support team. Without this data, the router will not be able to access the Internet, even if all other settings are correctly executed.

We also recommend that you update your router firmware in advance if you have access to the Internet through another device, which will help avoid compatibility errors. Check the current firmware version on the sticker under the router - if it is older than 2.XX.XX, it is better to update before setting up.
