How to set up a new router Xiaomi 4C: From unpacking to fine optimization

Xiaomi Router 4C — It's a compact but powerful router that can provide a stable Internet connection for an apartment or a small office, but even the most advanced device won't show its best without the right setup. In this article, we will analyze not only the basic steps for connecting, but also hidden functions that the manufacturer does not always advertise.

You've just unpacked a box of white router boxes and you're wondering, where do you start? Take your time plugging it into the outlet -- check the outlet first (5V/1A), network cable (usually yellow) and brief instructions in several languages (except Russian, alas.

Features of Xiaomi Router 4C It's based on Xiaomi's MiWiFi firmware, which is different from the standard TP-Link or Asus interfaces, which means that some of the custom settings may be in unexpected places. After reading this article, you will be able to navigate the menu as well as the engineer.

Preparation for setting up: what to do before turning on the router

Before connecting Xiaomi Router 4C To get electricity, take some simple but important steps that will save you time and save you from any problems you might have in the future.

First, determine the optimal location for the router. 4C It has two external antennas, but only enough power to cover the surface. 2-3 rooms in a standard apartment. avoid accommodation near:

• 📺 Microwave ovens (they operate at 2.4 GHz and create interference)
• 🔌 Sources of electromagnetic radiation (refrigerators, washing machines)
• 🧱 Thick concrete walls or metal structures
• 🌿 Large houseplants (they absorb signal, especially cacti)

Second, prepare the data from your provider.

• 🔑 Login and password for Internet connection (usually specified in the contract)
• 📡 Connection type: Dynamic IP, PPPoE, Static IP or L2TP
• 🔢 VLAN ID (If your provider uses port binding)

⚠️ Note: If you connect to the Internet via PPPoE, check if your provider is blocking the connection of new devices. MAC-The address of the first device connected, in which case you'll need to clone. MAC-address of the old router or call support.

Finally, download the official Mi WiFi app (available for Android and iOS) which will make the setup process much easier, especially if you don’t like to mess around with the web interface.

First Internet connection and connection

Now, let's get to the practice. Connect the power supply to the router and plug it into the socket. The indicator on the front should flash orange, which means that the device boots. 30-60 The indicator will turn blue (waiting mode connection).

There are two options for the development of events:

1. Connection through WAN-Port (recommended for most users): Take a network cable from your provider (usually bundled with the Internet) and connect it to the yellow port on the back of the router (marked as WAN).
2. Connection through LAN-Port (if your provider uses the technology) GPON In this case, the cable connects to any of the three black ports (LAN1-LAN3).

After connecting the cable, the indicator on the router should change color to purple (if the Internet is successfully connected) or continue to flash orange (if authorization is required).

Now, connect to the router's temporary Wi-Fi network. It'll be called Xiaomi_XXXX (where XXXX — last-minute MAC-The default password is on the sticker at the bottom of the router. Once connected, open the Mi WiFi app or go to the browser at the address 192.168.31.1.

Set up the main parameters of the network

Once you've successfully connected to the time network, you'll be greeted by a customizator. If you're using Mi WiFi, the process will be as simple as possible -- just follow the on-screen prompts. However, we recommend that you go to the web interface at least once to manually adjust the settings.

In the web interface (192.168.31.1), you will be asked to enter your username and password.

• Login: admin
• Password: Admin or the one on the router sticker

Once you log in, you'll be taken to the home page, and you'll need to configure three key parameters here:

1. Type of Internet connection (Network) → Select the one your ISP uses (most commonly PPPoE or Dynamic). IP). For PPPoE, enter the login and password from the contract.
2. Wi-Fi network name and password (Wi-Fi) → Basic Settings: Use a unique network name (don’t use personal data!) and a strong password (minimum 8 characters, with numbers and capital letters).
3. Mode of operation Wi-Fi (Wi-Fi) → Advanced Settings, please keep it 2.4 GHz in mode 11b/g/n (for maximum compatibility) and channel width 20/40 MHz.

⚠️ Note: If your provider uses a binding MAC-address, go to the Network → MAC Clone and clone MAC-The address of the old device (or computer that used to have the Internet) without it, the Internet may not work.

An important nuance for users of dual-band devices: Xiaomi Router 4C It only works in the 2.4 GHz band. If your devices support 5 GHz, the router will not be able to provide maximum speed. 4A or AX3600.

Optimization of connection speed and stability

The basic setup is complete, but that's not all. 4C I have worked to the maximum of my capabilities, you need to optimize several parameters.

Start with a firmware update. Go to System. → Firmware Upgrade and check for updates. Xiaomi regularly releases patches that fix vulnerabilities and improve performance. If an update is available, install it. 2-5 minutes after which the router will restart.

Next, set up QoS (Quality of Service), a feature that prioritizes traffic, which is especially useful if you have the following:

• 🎮 Online games (require minimum ping)
• 📺 Streaming video (requires a stable speed)
• 💼 Video Conferencing (Sensitized to Delays)

Enable QoS in Advanced → QoS Settings and select Game Mode (for gamers) or Video Mode (for streaming). MAC-Device addresses that need to be prioritized.

Another useful tool is the speed limit for individual devices, which is true if someone at home eats up all traffic with torrents or online games. → Bandwidth Control and set limits for specific IP or MAC-address.

💡

If you often lose your connection, try manually setting a static Wi-Fi channel (e.g. 6 or 11) instead of Auto mode.
