Standard Entry Address and Authorization
The main address for accessing the web interface of Xiaomi routers is 192.168.31.1. Also often the domain name miwifi.com works, however, its use depends on the DNS settings and may not work without an active connection to the global network.

Features of Chinese and Global Firmware
Xiaomi AC2100 routers often come with a Chinese version of the firmware that doesn't have English or Russian built-in. The interface is entirely in Chinese, which causes difficulties for users. However, the menu structure is logical. The main page (Status) shows the network map. The settings button is usually in the upper right corner or indicated by a gear. The global version is English and is selected when you first log in or update.
To change the language in the Chinese version, sometimes you just need to go to the Settings section, then to Status or Common Settings, and find the item “Language.” If there is no Russian, choose English. If you can’t change the language, you will have to navigate by icons or use a translator in the browser (Google Chrome can translate pages in full).
| Chinese term (example) | Russian translation | Function |
|---|---|---|
| (Chángyòng shèzhì) | General settings | Basic system parameters and Wi-Fi |
| (Shàngwǎng shèzhì) | Internet settings | Configure PPPoE, DHCP, Static IP |
| Wi-Fi (Wi-Fi shèzhì) | Wi-Fi settings | Network name, password, SSID hiding |
| (Guǎnlǐ zhuàngtài) | Management status | System information, reboot |
Global firmware is more user friendly, but may have a stripped-down functionality compared to Chinese (for example, the lack of some modes of operation or VPN settings). Many experienced users prefer to leave Chinese firmware using a browser translator, or install third-party firmware such as Padavan or OpenWrt, which are fully localized and have advanced functionality.

In the "Administration" or "System" section, check for firmware updates. The current firmware version closes security vulnerabilities and improves stability. Don't neglect this step, especially if the router is available from an external network. After all the settings, it is recommended to restart the device through the web interface to apply all the parameters.
