On Xiaomi routers DHCP-The server is turned on by default, but its standard settings are not always optimal, for example, the range of addresses you can give away may overlap with the redundant ones. IP, And the lease time is to be too short, which leads to frequent reconnections:

• 🔄 Avoiding conflict IP-address-to-device;
• 🛡️ Protect the network from connecting third-party devices;
• ⚡ Accelerate the connection of gadgets due to optimal rental time;
• 📡 Reserve fixed fixed IP for servers, printers or cameras.

If you are using a router in repeater mode or connected to another router, it is better to turn off DHCP on Xiaomi to avoid double address distribution.

Preparation for setting up: login to the router web interface

2. Open your browser and type in the address bar 192.168.31.1 (standard IP for Xiaomi) or miwifi.com.

If you have devices on your network that need a constant IP (for example, IP-camera, NAS-servers or printers, use the redundancy function DHCP (It is also called Static.

3. Select the device from the list of connected or enter it MAC-manual.
4. Specify what you want. IP-address (e.g. 192.168.31.50 for printer).
5. Save the settings.

Important: Reserve IPs should be outside the DHCP range to avoid conflict, for example, if DHCP is giving out addresses from.100 to.200, reserve addresses in the range of.2 to.99.

Example of correct configuration:

• 🖨️ Printer: 192.168.31.50 (MAC: 00:1A:2B:3C:4D:5E);
• 📹 IP-camera: 192.168.31.51 (MAC: AA:BB:CC:DD:EE:FF);
• 💾 NAS-server: 192.168.31.52 (MAC: 11:22:33:44:55:66).

• 📊 Check the range DHCP static IP cross-roads.
• 🔄 Reduce your lease time to 12 hours to free up unused addresses faster.
• 🛡️ Turn on the filtering by MAC-Addresses if unknown devices appear on the network.
