Connecting Xiaomi to a computer via Wi-Fi: all the ways and nuances

Wirelessly connecting Xiaomi devices to your computer via Wi-Fi saves time and eliminates the need to use cables. USB-The port of the smartphone is occupied or damaged, as well as for remote control of the Redmi screen or POCO But not everyone knows that there are several ways to do this, from standard file transfer to full debugging over Wi-Fi (ADB), It offers opportunities for developers and enthusiasts.

In this article, we will discuss all the current methods of connection, their pros and cons, as well as typical errors that prevent you from establishing a connection. 10/11 MacOS, what applications will be needed for this and how to circumvent the restrictions MIUI. We will pay special attention to security – because wireless connection requires protection from unauthorized access.

If you have previously used only USB-And then you can actually go to Wi-Fi, to send photos, to install apps, or even to stream a screen to a big monitor. MIUI 14+ You will find the current settings here, which are often hidden in new firmware versions.

1. Device Preparation: What to Do Before Connecting

Before you connect Xiaomi to your computer over Wi-Fi, make sure both devices are ready for this. On the smartphone side, it is critical to enable several features without which the connection simply will not be established.

On Xiaomi Android devices (including Redmi Note 12, POCO X5, Mi 11 et al.) check:

• 🔋 Battery charge not lower than 30% – at a low level, the system can block background processes, including data transmission.
• 📶 Wi-Fi and Bluetooth are enabled (even if you plan to use only Wi-Fi, some methods require Bluetooth to set up initially).
• 🔓 Developer mode is activated – it is needed for ADB Wi-Fi and some third-party applications.
• 🛡️ firewall MIUI Does not block connections - check in Settings → Annexes → Permits → Auto-start.

On the computer, training depends on the chosen method:

• 🖥️ For Windows: install the latest Xiaomi drivers (you can download on the official website) and ADB Tools (part of Android) SDK).
• 🍎 For macOS: Install Android File Transfer (for file transfer) and Homebrew with adb package.

⚠️ Note: If you use a corporate or public Wi-Fi network with portal authentication (for example, in hotels or airports), connect by ADB Wi-Fi won't work. In such cases, create a hot spot on your smartphone and connect your computer to it.

Please note that some features (such as Miracast) may not be supported on older Xiaomi models (until 2019 release).

2. Method 1: Transfer files over Wi-Fi (without Wi-Fi) USB)

The easiest way is to use built-in tools. MIUI It's a third-party application for transferring files over a local network, it doesn't require developer rights and it's suitable for most users.

V MIUI 12/13/14 There is a built-in feature "File Transfer over Wi-Fi", but it is hidden in the Settings menu → Connections and sharing → Alternatives are apps like Xender, Send Anywhere or LocalSend (like AirDrop for Android).

Step-by-step instructions for LocalSend (recommended):

1. Install LocalSend on your smartphone (official website) and computer (Windows/macOS/Linux).
2. Connect both devices to the same Wi-Fi network.
3. On your smartphone, open LocalSend, click Send and select files.
4. On a computer in a web interface (http://localhost:53210) or desktop application accept files.

Advantages of this method:

• 🚀 Transmission speed to 10-15 MB/s (depends on the router).
• 🔒 Traffic encryption (localSend is used) TLS).
• 📁 Support for folders and large files (up to 2 GB in the free version).

⚠️ Note: If files are not transferred, check if the antivirus on your computer blocks them. Add LocalSend to exceptions or temporarily disable protection.

3. Method 2: ADB Wi-Fi – Full control of Xiaomi

ADB (Android Debug Bridge, which allows you to control your smartphone wirelessly from your computer, install applications, execute commands, copy system files, and even unlock the bootloader. This method requires pre-configuration, but opens up maximum possibilities.

To start, turn on the developer mode on Xiaomi:

1. Go to Settings. → The phone.
2. Click on the MIUI version 7 times until the notification “You are a developer!” appears.
3. Back to Settings → Additionally. → For developers.
4. Activate Debugging on USB and Wi-Fi debugging.

Now connect your smartphone to your computer once USB (This is required for authorization):

adb tcpip 5555

Then turn off the cable and connect via Wi-Fi:

adb connect [IP-device address]:5555

To find out IP-Xiaomi address, go to Settings → Wi-Fi → [your network] → See the details.

If after the command adb connect there is an error "unable to connect", check that the smartphone in the section For developers included the item "Network debugging" (in some versions) MIUI It is hidden – use the search by settings).

After successful connection, you can:

• 📱 Control your smartphone from a PC via scrcpy (screen streaming).
• 📦 Install APK-files with the adb install command [path to file].
• 🗃️ Copy files: adb pull /sdcard/DCIM/.

Method 3: Remote screen (Miracast and alternatives)

If you need to not only transfer files, but also control your smartphone from your computer (for example, to stream games or presentations), use Miracast protocols or specialized programs like scrcpy.

For Windows. 10/11 Miracast support is built in:

1. On Xiaomi, turn on the Wireless Display in Settings → Connections → Wireless display.
2. On the computer, press Win. + K and select your smartphone from the list.
3. Confirm the connection on both devices.

For more flexible management, we recommend scrcpy (works on the Windows/macOS/Linux):

scrcpy --bit-rate 8M --max-size 1080

This command will run screen streaming with resolution 1080p 8 Mbps bitrate (optimum for most Wi-Fi networks).

5. Solving the Problem: Why Xiaomi Doesn't Connect Over Wi-Fi

Even if you set up the connection correctly, you can interrupt it. Let's look at the typical errors and their solutions:

Problem 1: ADB Can't see the device on Wi-Fi

• 🔌 Make sure your smartphone and computer are on the same subnet (for example, both are connected to the router, not to different access points).
• 🔄 Reset the service ADB Adb kill-server and adb start-server.
• 📱 On Xiaomi, check that the "Wi-Fi Debugging" item is included in the For Developers (in some firmware it is called "Network Debugging").

Problem 2: Slow file transfer

• 📶 Switch the router to 5GHz (if supported) – it’s less busy.
• 🖧 Change the Wi-Fi channel in your router settings (use Wi-Fi Analyzer to find a free channel).
• 🔌 Connect your computer to the router via cable (if possible) – this will eliminate delays.

Problem 3: Scrcpy shows a black screen

• 🔄 Update your video drivers on your computer (especially for Intel) HD Graphics).
• 📱 On Xiaomi, turn off "Optimize" MIUI" In Settings → Special facilities → Optimization MIUI.
• 🖥️ Start scrcpy with administrator rights.

⚠️ Attention: If you are using VPN on a computer or smartphone, disconnect it before connecting. VPN Changes traffic routing, which can block local Wi-Fi connections.

💡

For a stable job. ADB On Wi-Fi, add a rule to the Windows firewall that allows incoming connections to port 5555. Use the command: netsh advfirewall firewall add rule name="ADB" dir=in action=allow protocol=TCP localport=5555

6.Security: How to Protect Connection from Hacking

Wireless connectivity is convenient, but it opens up potential vulnerabilities. Follow these guidelines to protect your data:

Basic measures:

• 🔐 Use it. WPA3 on the router (if supported) or at least WPA2-AES.
• 📵 Turn it off. ADB Wi-Fi and Wireless Display after use.
• 🔄 Update regularly MIUI — In new versions, vulnerabilities are closed (for example, in the MIUI 14.0.5 fixes a data leak error via ADB).

Additional protection:

• 🛡️ Set up static. IP for a smartphone in the router and allow connection only from this address.
• 🔑 Change the port. ADB non-standard (e.g, 5556) command: adb tcpip 5556 adb connect [IP]:5556
• 📱 B Settings → Password and security enable "Blocking when connected" USB" (It also works on wireless connections).

To check the security of the connection, use the command:

adb shell netstat -tuln

It'll show you all the active network connections on your smartphone. IP-Addresses, turn off immediately. ADB And check the device for viruses.

💡

Never connect to the ADB Wi-Fi on public networks (cafes, airports) Only use a home or mobile hotspot with a strong password.

7.Alternative methods: cloud services and USB Wi-Fi

If standard methods do not work, consider alternatives:

1. USB via Wi-Fi (USB/IP)

Technology USB over IP allows for emulation" USB-It's connected to the network:

1. Install it on the computer. USB Network Gate or USB Redirector.
2. On Xiaomi, turn it on. USB-debugging and plug in ADB.
3. Redirect. USB-Port via command: adb forward tcp:31000 tcp:5555

This method is useful for programs that require physical USB (For example, the Mi Flash Tool).

2. Cloud services with local synchronization

Applications like Syncthing or Resilio Sync create encrypted applications. P2P-Connecting devices over Wi-Fi without uploading files to the Internet is limited only by your router.

3. RNDIS Wi-Fi (for experienced users)

You can set up Xiaomi as a USB-The modem is Wi-Fi, but it requires root rights and changes to system files:
