Xiaomi Router 4 is a popular home networking solution for balancing price, performance and functionality. However, even a simple device requires the right setup to unlock the full potential, from stable Wi-Fi to protection from external threats.
Unlike budget counterparts, Xiaomi Router 4 supports dual-band Wi-Fi (2.4 GHz and 5 GHz), has four gigabit ports. LAN It's managed through the handy mobile application Mi Wi-Fi, but without a good configuration, even these benefits may not be needed. We'll look at not only the basic steps, but also the hidden settings that are often left out in standard manuals.
Preparation for setting up: what to do before turning on the router
Before you connect the Xiaomi Router 4 to the network, make sure you have everything you need.
Mandatory conditions:
- ๐ถ Internet Service Provider: Specify the type of connection (PPPoE, Dynamic Connection) IP, static IP) โ This information can be found in the contract or specified in the support service.
- ๐ฑ Smartphone or PC: to set up via the Mi Wi-Fi app (Android/iOS) or web interface (any browser).
- ๐ Ethernet Cable: Usually included, but if not, prepare a patch cord RJ-45 connect to the provider.
- โก Power source: router runs from the network 12V/1The adapter must meet these parameters.
If you are replacing an old router, donโt disconnect it from the network beforehand โ write down the current PPPoE settings (logins/passwords) or settings first. IP, Also check if your plan supports dual-band Wi-Fi: some providers limit speeds to 5 GHz.
โ ๏ธ Note: If your provider uses a binding MAC-Cloning the router before replacing it MAC Old device in the settings of the new (optional) MAC Clone in the web interface, otherwise the Internet may not work.
First connection and entrance to the control panel
The initial setup process for Xiaomi Router 4 takes no more than 10 minutes, if you follow a clear algorithm, and letโs consider both options โ through the application and through the browser.
Method 1: Configure via the Mi Wi-Fi app
This is the easiest method for beginners:
- Download the Mi Wi-Fi app from Google Play or the App Store.
- Connect the router to power and wait until the indicator on the front panel starts flashing orange (connection waiting mode).
- Launch the application and select Add Device โ Router.
- Follow the instructions on the screen: the application will automatically find the router and prompt you to enter data from the provider.
Method 2: Web interface (for experienced users)

Basic settings: Wi-Fi, password and security
By default, the router creates two Wi-Fi networks: Xiaomi_XXXX_2.4G and Xiaomi_XXXX_5G, where XXXX โ last-minute MAC-Both networks are protected by a standard password on the device sticker, which should be changed first.
How to Change Wi-Fi Name and Password
Go to the Wi-Fi section โ Wi-Fi settings and:
- ๐ Name of the network (SSID): Give a unique name for each range (e.g, MyHome_2.4 and MyHome_5). Avoid Cyrillic and gaps.
- ๐ Password: Use a combination of 12+ symbols with numbers, capital letters and special symbols (for example, K7#pL9!mQ2$v).
- ๐ก๏ธ Type of security: Select WPA2-PSK (The most reliable option for home networks).
- ๐ถ Channel width: for 2.4 GHz, leave 20 MHz (best compatibility), for 5 GHz, 80 MHz (maximum speed).
Once you save your settings, all devices will be disconnected from Wi-Fi, and you will have to reconnect them with a new password. If you use Xiaomi smart devices (lamps, sensors), temporarily leave the old network active so you do not lose connection with them.
Setting up the guest network
The guest network isolates the connected devices from your main LAN, which is useful for security, to activate it:
- Go to Wi-Fi. โ Guest network.
- Enable the option and set a separate name/password.
- Limit speeds (e.g., to 50 Mbps) so guests donโt occupy the entire channel.
- Set an automatic shutdown timer (for example, after 6 hours).
โ ๏ธ Attention: The guest network has defaulted to disable local resources (printers, network drives). If you want to allow guest printing, turn on the option to access the local network in the guest network settings.
๐ก
If you have frequent guests, create a QR-code for the guest network in the router's settings and print it out.
Advanced settings: Optimization of speed and stability
Even after a basic configuration, the network may not work perfectly: slow speeds of 5 GHz, connection breaks or lag in online games, problems often solved by fine-tuning parameters.
Choice of Wi-Fi channel
By default, the router selects the channel automatically, but in apartment buildings, this leads to interference.
- Install Wi-Fi Analyzer (Android) or NetSpot on your smartphone (iOS/macOS).
- Scan the ether and determine the least loaded channels for 2.4 GHz (optimally: 1, 6 or 11) and 5 GHz (for example, 36, 44, 149).
- In the routerโs web interface, go to Wi-Fi โ Additional settings and manually set selected channels.
For 5 GHz, you can also include DFS (Dynamic Frequency Selection: This will allow for the use of channels that are normally reserved for radar, but keep in mind that when radar is detected, the router will automatically change channel, which can cause a short-term connection break.
QoS (Quality of Service)
QoS allows you to prioritize traffic for critical tasks (such as video calls or games). In the Xiaomi Router 4, this feature is called Bandwidth Management:
- ๐ฎ For gamers: add the device to the priority MAC-Address or select the type of traffic of the Game.
- ๐น For streaming: prioritize services like YouTube, Netflix or Twitch.
- ๐ For calls: allocate the maximum bandwidth for VoIP (Skype, Zoom, WhatsApp calls).
Limit the speed for background traffic (such as torrents or updates) to 10 Mbps so it doesnโt interfere with basic tasks. Set up a QoS schedule if you need top speed during the day and save resources at night.
| Parameter | Recommended value | Explanation |
|---|---|---|
| MTU | 1480 | Optimal for most providers. If you have connection issues, try 1472. |
| DNS | 1.1.1.1 / 8.8.8.8 | Fast and reliable. DNS Cloudflare and Google. Replace the standard ones. DNS provider. |
| Beacon Interval | 100 ms. | Reducing the value accelerates device reconnection, but increases the load on the network. |
| DTIM Interval | 3 | Low value improves responsiveness, but reduces battery life on connected devices. |
๐ก
If, after the channel changes, or MTU The Internet is gone, so you can go back to the factory settings and try the other values.
Update firmware and reset settings
Regular firmware updates are critical for security and stability. Xiaomi Router 4 supports two ways to update: via a web interface and manually through a file.
Automatic update
The simplest method is:
- Go to Software Update in the web interface.
- Click Check for updates.
