After successful login, the system will prompt you to create an account. Xiaomi Or log in using an existing account. If you don't have one, register (an email address or phone number is required). This is a mandatory step—if you don't link an account, some features will be blocked.

⚠️ Attention: If the router was previously used by another owner, perform a reset (Reset) and link it to your account Xiaomi. Otherwise, access to some settings (for example, Guest network) will be limited.

Basic network setup: Internet, Wi-Fi, and password

After logging in, you'll be taken to the main interface page. Go to the section Settings → Quick Setup (or Quick Setup (in the English version). Here you need to configure three key parameters:

1. Internet connection type:
   • 🔄 Dynamic IP (DHCP) - choose if the provider automatically assigns an address (most often Rostelecom, MTS).
   • 📝 Static IP — if the provider has issued fixed addresses (check them in the contract).
   • 🔑 PPPoE — for connections with authorization (login/password), for example, Beeline or Third Transport Ring.

Wi-Fi settings:

• 📡 Network name (SSID) - come up with something unique (do not use personal information!).
• 🔒 Password - minimum 8 characters, with numbers and capital letters.
• 📶 Channel - select Auto or specify manually 1, 6 or 11 (less busy).
• Administrator password — protects access to router settings (not to be confused with a Wi-Fi password!).

After saving, the router will reboot (this will take about 1 minute). If the internet still doesn't work:

• 🔄 Double-check your connection type (check with your provider).
• 📞 Call support - the router's MAC address may need to be bound.

Example of setting up remote access to the camera:

Parameter	Meaning
Rule name	Camera_Stream
Protocol	TCP
External port	8080
Internal IP	192.168.31.100 (camera address)
Inland port	80

⚠️ Attention: Opening ports reduces network security. Use static IP addresses for devices (in DHCP → Address Reservation) and update passwords regularly.

Firmware update and factory reset

Regular firmware updates fix vulnerabilities and improve performance. To update the software:
