• 📦 Preparation for sale or transfer: Before you give the router to another user, you must delete all personal data and settings.

It is important to understand that reset removes all user settings, including:

• Wi-Fi name and password (SSID)
• Provider connection parameters (PPPoE types, DHCP, Static IP)
• Port settings, DNS, MAC-filtering
• Guest network and parental control

⚠️ Note: If the router is connected to the Xiaomi Smart Home system (for example, to manage smart devices via Mi Home), after the reset, you will have to reconfigure the integration.
