Usage Xiaomi Mi Box While a set-top box transforms a regular TV into a powerful multimedia center, it often requires a computer for convenient use. Connecting the set-top box to a laptop wirelessly unlocks advanced features, from fast file transfers to remote control and app debugging. This eliminates unnecessary cables and allows users to manage content without leaving the couch.
There are several proven methods for implementing a connection, each of which addresses specific needs of a digital ecosystem owner. The choice of method depends on what you plan to do: stream a screen image, use the set-top box as storage, or develop software. In this article, we'll take a detailed look at all the current options for integrating devices into a single network.
Preparing equipment and setting up the network
Before beginning any manipulations, it's necessary to ensure that both devices are in the same network environment. This is a fundamental requirement, without which detection between the devices is technically impossible. Local area network must be configured correctly, and the router must work stably.
Make sure your laptop and Mi Box S or an older model are connected to the same router. If you have a dual-band router that supports both 2.4 GHz and 5 GHz, it's better to use the 5 GHz frequency for faster data transfer, especially if you plan to stream high-definition video.
⚠️ Note: If your router is configured to separate networks (guest network or client isolation), devices may not see each other even when connected to the same SSID. Temporarily disable the "AP Isolation" feature in your router settings.
It's also worth checking that network debugging is enabled on your set-top box if you plan to use advanced control methods. Standard operation only requires an active Wi-Fi connection. To test the connection, you can try opening any website on the set-top box via a browser.
Mirror your laptop screen to your TV (Miracast)
The most popular use case is displaying images from a computer display on a large TV screen. In the operating system Windows 10 And Windows 11 This feature is built-in natively and does not require installation of additional software on the PC. Technology Miracast Allows you to duplicate your screen or extend your desktop wirelessly.
On the set-top box, you need to launch the app to receive the signal. Depending on the firmware version Android TV, it may be called "Cast," "Wireless Display," or "Miracast." Once the app launches, a connection screen will appear.
On your computer, press the key combination Win + KThe system will begin searching for available displays. Your set-top box's name should appear in the list. Click it, and within a few seconds, the image from your laptop will appear on the TV. Image quality depends on the router's power and distance.
- 📺 Click the "Connect" button in the Windows quick actions menu.
- 📡 Make sure the signal reception application is open on the set-top box.
- 💻 Select the projection mode: "Repeat" or "Expand".
- 🔊 To transmit audio, select the "Wireless Display" output device in the volume mixer.
Managing files via SMB and network environment
To view movies or photos stored on your laptop's hard drive, it's best to use the protocol SMB (Server Message Block). It allows you to share a folder on your computer, making it accessible to the set-top box over the network. This is the ideal option for creating a home media server without purchasing an additional NAS.
On Windows, you need to open the properties of the desired folder, go to the "Access" tab, and grant read permissions to the current user group. It's important to remember the computer's IP address, which can be found by entering the command in the command prompt. ipconfig.
On Xiaomi Mi Box Open a file manager, such as CX File Explorer or X-plore. Under Network, select New Connection or SMB. The system will automatically find the computer on the local network. If this doesn't happen, enter the IP address manually.
| Parameter | Meaning on PC | Meaning on Mi Box |
|---|---|---|
| Protocol | SMB v1/v2/v3 | SMB Client |
| Address | 192.168.1.X (local IP) | Entered manually during search |
| Port | 445 | 445 (standard) |
| Login | Windows username | Entered upon connection |
After successful authorization, you'll gain access to your laptop's file system. You can play video files weighing tens of gigabytes directly, without copying them to the console's internal storage. This saves space and time.
☑️ Setting up a shared folder
Using ADB for Advanced Control
For enthusiasts and developers, an indispensable tool is Android Debug Bridge (ADB). This command-line tool allows you to control the console from your computer: install applications (APKs), remove system junk, take screenshots, and even emulate keystrokes.
To activate debug mode, go to the console settings Settings → About device → AssemblyTap "Build" seven times until the "You are now a developer" message appears. Then, in the "For developers" menu that appears, enable "USB debugging" (this also works over Wi-Fi).
Platform tools must be installed on your computer. ADBAfter installation, open a terminal or command prompt in the tools folder. The first connection command looks like this:
adb connect 192.168.1.XX:5555Where 192.168.1.XX — This is your set-top box's IP address, which can be found in the network settings. After entering the command, a debugging permission request will appear on the TV screen. You'll need to agree using the remote. Now you can send commands, such as installing an app:
adb install -r application_name.apk⚠️ Note: Android TV firmware interfaces change frequently. Menu items may have different names depending on the OS version and regional firmware. If you can't find the item you need, use the search in the settings.
List of useful ADB commands
adb shell screencap -p /sdcard/screen.png (take a screenshot)
adb pull /sdcard/screen.png (download screenshot to PC)
adb shell pm list packages (list all packages)
adb reboot (reboot device)
Chrome Browser Content Casting
If you need to show a presentation or video from a website that doesn't support live TV streaming, use the Cast feature in your browser. Google ChromeThis method is more stable than system screen casting, as it uses Google Cast protocols, which are native to the Android TV platform.
Open your laptop's browser, click the three dots in the upper right corner, and select "Cast." The browser will scan the network and find your Mi BoxYou can choose to broadcast a specific tab or your entire desktop.
The advantage of this method is the ability to control playback from your laptop keyboard. You can pause, rewind, or switch tabs, and the image on your TV will change accordingly. The image quality is typically higher than with Miracast.
- 🌐 Open the Chrome browser menu (three dots).
- 📡 Select "Cast".
- 🖥️ Click "Sources" to select a tab or the entire screen.
- ▶️ Click on your set-top box name to start broadcasting.
Solution and speed optimization
Despite the simplicity of setup, users may encounter issues. These are most often related to an unstable Wi-Fi signal or incorrect firewall settings. If your laptop doesn't detect the console, try temporarily disabling your antivirus or firewall on your PC.
Another common cause of problems is an outdated wireless adapter driver on your laptop. Update your drivers through Device Manager or the manufacturer's website. It's also worth checking if your router has speed limits for individual devices.
To ensure stable 4K content streaming, ensure your Wi-Fi channel isn't overloaded by neighboring networks. Use Wi-Fi analyzer apps on your smartphone to find a free channel and switch your router to it via the web interface.
Why doesn't my laptop see Mi Box when searching for devices?
Most often, the problem is that the devices are connected to different subnets (for example, one to a guest Wi-Fi network and the other to the main network) or that access point isolation is enabled on the router. Also, check whether the receiving app is allowed in Windows Firewall.
Is it possible to connect Mi Box to a laptop via Bluetooth?
Theoretically, yes, since the console has a Bluetooth module, but using standard Windows tools, this is extremely difficult and impractical for file or screen transfer. Bluetooth is primarily intended for connecting gamepads, keyboards, and headphones.
How can I find out the IP address of the set-top box for connection?
Go to Mi Box settings, select "Network & Internet," and click on your Wi-Fi network name. The menu that opens will display detailed information, including the IP address (e.g., 192.168.1.54).
Does screencasting affect picture quality?
Yes, wireless streaming always involves video compression. A weak signal may cause artifacts, audio and video desynchronization, or a drop in resolution. For optimal quality, use an HDMI cable.
