We cover all options, including setup via Mi Wi-Fi App and a web interface. If you've never configured a router before, don't worry: this guide is designed for beginners, but also includes advanced tips for experienced users.

1. Preparing for connection: what you need to check before starting

Before you begin setup, make sure you have everything you need. Often, problems arise due to trivial issues: a faulty cable, an unsuitable power supply, or incorrectly entered ISP data.

Here mandatory checklist before connecting:

Make sure the router Xiaomi 4C (model R4CM or R4C) compatible with your provider

Prepare an Ethernet cable from your internet service provider (usually blue or gray)

Check for the presence of a 12V/1A power supply (included)

Download the app Mi Wi-Fi (App Store/Google Play) or prepare your computer for setup via a browser

Check with your provider for the connection type (PPPoE, L2TP, dynamic IP) and login/password (if required)-->

Please pay special attention to Internet connection typeMost Russian providers (Rostelecom, Beeline, MTS, TTK) use PPPoE Login and password authentication required. If you don't know your details, call support or check your contract. Without the correct details, the router will not be able to connect to the Internet, even if everything else is configured correctly.

Also check if the router has been used before. If so, perform a factory reset: hold down the button Reset on the back panel for 10 seconds until the indicator starts flashing yellow. This will prevent conflicts with previous settings.

2. Connecting the Xiaomi 4C router to the network: step-by-step instructions

Now let's move on to the physical connection. Follow the instructions carefully—the order is important!

1. Connect the power supply Connect the router to a power outlet and plug it into a power outlet. Wait until the blue indicator lights up (this means the device is ready for setup). If the indicator is flashing orange, see the section "Typical Mistakes".

2. Connect the router to the Internet: take the cable from your ISP (usually it's connected to your modem or comes straight from the wall) and plug it in blue WAN port On the back of the Xiaomi 4C. Make sure the cable is securely inserted—sometimes connectors can be tight.

3. Connect the device to configure:

- Option 1: through Wi-Fi - find the network with the name Xiaomi_XXXX (where XXXX are the last digits of the MAC address) and connect to it. The default password is located on the sticker on the bottom of the router.

- Option 2: through cable - connect any of the black ports LAN on the router with the computer's network card.

4. Run the setup:

- If you use Mi Wi-Fi App — open the application and follow the prompts (the router will be detected automatically).

- If you are setting up via a browser, enter in the address bar 192.168.31.1 or miwifi.com.

3. Internet setup: choosing the connection type

After the physical connection, you need to tell the router how to receive internet from the provider. Everything here depends on connection type, which is used by your operator. Let's look at the three most common options.

Option 1: PPPoE (the most popular in Russia)

This protocol requires a login and password. It is commonly used by Rostelecom, Beeline, MTS, and other major providers. In the setup interface, select:

• 🔹 Connection type: PPPoE
• 🔹 Enter login and password (specified in the contract or SMS from the provider)
• 🔹 Specify MTU: 1480 (this is the optimal value for most networks)
• 🔹 Check the box Connect automatically

#### Option 2: Dynamic IP (DHCP)

Used by some providers (for example, Dom.ru in some regions). There's no need to configure anything here—just select:

• 🔹 Connection type: Dynamic IP (DHCP)
• 🔹 Save settings

#### Option 3: Static IP

Rarely encountered by home users, but sometimes required for corporate plans. You'll need to enter:

• 🔹 IP address, subnet mask, default gateway
• 🔹 DNS servers (can be used 8.8.8.8 And 8.8.4.4 from Google)

After selecting the connection type, save the settings and wait for the router to reboot. If the internet still doesn't work, check the information you entered or contact your provider.

How can I find out the connection type from my provider?

If you don't know what type of connection is being used, call support and ask: "What authentication protocol is being used to connect to the Internet: PPPoE, L2TP, PPTP, or dynamic IP?"

The connection type can also be specified in your provider's personal account in the "Services" or "Internet" section.

4. Setting up a Wi-Fi network: name, password, and security

After connecting to the internet, you need to set up a wireless network. Open the section Wi-Fi settings in the web interface or app. Here you can:

• 🔹 Edit network name (SSID) — choose a unique name to avoid confusion with neighboring routers.
• 🔹 Install password - Use at least 8 characters with numbers and letters (e.g. Kotik123!Miau).
• 🔹 Select operating mode:
  • 📶 2.4 GHz - passes through walls better, but can be loaded by neighboring networks.
  • 📶 5 GHz - higher speed, but shorter range.
  • 📶 2.4 + 5 GHz (one name) — the router itself selects the optimal range (recommended).
• 🔹 Set up encryption — choose WPA2-PSK (the safest option).

If you have a dual-band router (model Xiaomi 4C Dual Band), you can split the networks into two names - for example, MyWiFi_2G And MyWiFi_5GThis is convenient if some devices (for example, older smartphones) do not support 5 GHz.

After saving the settings, the router will reboot, and you'll be able to connect to the new Wi-Fi network. If the password doesn't work, check the case (passwords are case-sensitive) or reset the settings.

5. Additional settings: guest network, parental controls, and updates
