• 📄 Data for Internet connection: connection type (PPPoE, DHCP, Static IP), login/password (if required).

If you do not know the connection parameters, you can specify them:

• 📞 Calling in support of the provider (the number is usually specified in the contract).
• 🖥️ Look at the settings on the old router (if any) in the section WAN internet.
• 🔍 On the provider's website in the personal account (for example, lk.rt.ru for Rostelecom).

⚠️ Note: If your provider uses a binding MAC-address (for example, as does Dom.ru), before connecting a new router be sure to register it MAC In your personal account or tell the operator, otherwise the Internet will not work!

Also check if your plan supports work through third-party routers. some providers (like the ones you're using) MGTS) They block the connection if the device is not on their list of approved devices, and then they may need to use a bridge mode on their equipment.

2. Connecting the router to power and provider: Step-by-step

Now, to the physical connection, follow the instructions carefully, because errors at this point can lead to a lack of Internet or improper Wi-Fi.

Step 1. Unpack the router and connect the power supply to the outlet 220V. The indicator on the front panel should light up orange (this means that the device is on, but not yet configured).

Step 2. Take an Ethernet cable from the provider and connect it to the blue port on the back of the router (it is usually signed). WAN If the cable is too long, don't twist it, it's best to lay it carefully to avoid interference.

Step 3: You'll need a computer or a smartphone to set up the setup. There are two options for connecting:

• 🖥️ Cable: Use the second Ethernet cable (from the kit) to connect the router to the PC/laptop. Connect one end to any yellow port (LAN), other - in the network card of the device.
• 📶 By Wi-Fi: on a smartphone or laptop, find a network with the name Xiaomi_XXXX (where XXXX — last-minute MAC-Connect to it without a password.

Once connected, the indicator on the router should change color from orange to blue (or start flashing), which is a signal that the device is ready to set up.

3. Set up an Internet connection via a web interface

Now, to the most important thing, the configuration of the Internet connection, it uses the router's web interface, which opens in the browser.

Step 1. Open any browser (Chrome, Firefox, Edge) and enter one of the addresses in the address bar:
