Modern users rarely carry cables, preferring wireless technologies to exchange data between devices. The question of how to connect a Xiaomi to a computer via Wi-Fi becomes relevant when a USB cable is unavailable or the port is occupied by another device. A wireless connection allows not only to transfer files but also to control the smartphone's screen, stream images, and even use the phone as a webcam.
In the ecosystem Android, on which the shell is based MIUI or HyperOS, comes with a variety of synchronization tools. You don't need to install complex third-party programs, as many features are built into the system by default. However, for maximum efficiency, specialized software is often required, turning your smartphone into a fully-fledged remote terminal.
The main advantage of this connection is speed and convenience. Wi-Fi Direct A USB port or a local network provide data transfer speeds comparable to USB 2.0, which is critical for working with 4K video or large archives. In this article, we'll cover all connection methods, from built-in options to professional tools for developers.
Preparing devices and setting up the network
Before setting up complex data transfer protocols, you need to ensure that the underlying infrastructure is working correctly. Both devices—and the smartphone— Xiaomi, and the computer must be on the same local network. This means they must be connected to the same router, either via Wi-Fi or an Ethernet cable.
It's important to check your firewall and antivirus settings on your PC. System blockers can often detect external connection attempts as a security threat and block the ports needed for synchronization. Make sure your network is marked as "Private" or "Home," not "Public."
⚠️ Important: If your router supports split-frequency bands (2.4 GHz and 5 GHz), make sure both devices are connected to the same frequency. Some older routers may isolate devices on different frequencies from each other, even if they are on the same network.
For stable operation, it is also recommended to disable the traffic saving mode on your smartphone. System MIUI is known for its aggressive battery optimization, which can kill background data transfer processes. Add file transfer apps to the exceptions list or use the "Unrestricted" mode for them.
Using the built-in Wi-Fi Sharing feature
The easiest way, which does not require installing additional software on your computer, is to use the built-in file manager. MIUIThis feature is implemented at the system level and operates via the FTP protocol, making it compatible with any PC.
To start the process, open the standard File Explorer or Files app. In the menu, find "Remote Control" or "Access from PC." Once activated, the system will generate an address that you need to enter into the address bar of any browser or File Explorer on your computer.
This method is ideal for quickly transferring photos or documents. However, it's worth keeping in mind that FTP protocol does not encrypt traffic by default, so using it on public Wi-Fi networks (cafes, airports) is not recommended.
This feature may be named differently in some firmware versions. If you can't find this option, try updating the File Explorer app through the store. GetAppsAlso, make sure that local network access is enabled on your phone in the app permissions settings.
Connecting via Mi PC Suite and Mi Share
The manufacturer's official software offers deeper integration. Although the classic Mi PC Suite for Windows has not been updated for a long time, new solutions like Mi Share (analogous to AirDrop) allows you to instantly transfer files between the brand's devices.
To use advanced control features, such as mirroring a smartphone's screen on a monitor, it's often necessary to enable USB debugging at least once. This is necessary to grant special permissions to the system. After the initial setup via cable, further operation can only be performed over the air.
Modern versions of shells HyperOS are implementing the protocol HyperConnect, which allows you to see open browser tabs from your phone on your computer and instantly share the clipboard. To use this feature, you must be logged into the same account. Mi Account on both devices.
☑️ Preparing for wireless connection
It's worth noting that the functionality of built-in apps may vary depending on the firmware region (Global, CN, EEA). In some cases, installing the Chinese version of the app is required for full functionality. Mi PC Suite, however, this may lead to problems with text encoding.
Professional synchronization via Scrcpy and ADB
For users who want full control over their device, the gold standard is a bundle ADB (Android Debug Bridge) and utilities ScrcpyThis method allows you to stream your screen with minimal latency (less than 40 ms) and a high bitrate, making it possible to even run mobile games on a PC.
Unlike simple file managers, this method requires initial setup. You'll need to download platform tools. Android SDK Platform-Tools From the official Google website. After unzipping the archive, you need to activate "Developer Mode" on your phone by tapping the build number seven times in the "About phone" section.
Then, in the Developer Options menu, enable "USB Debugging" and, crucially for our topic, "Wi-Fi Debugging." In modern versions of Android, this option allows you to connect to the device via IP address and port without using a cable.
adb connect 192.168.1.55:5555By entering this command in the console (after replacing the IP address with the current address of your smartphone), you will gain full access to the file system and interface. Scrcpy in turn, will launch a window with an image of the screen, allowing you to control the phone with a mouse and keyboard.
⚠️ Important: When using ADB over Wi-Fi, ensure the port (default 5555) is not blocked by a firewall. This method will also not work if the phone is in sleep mode, as the Wi-Fi module may be turned off to save power.
What to do if ADB doesn't see the device?
A common issue is missing ADB Interface drivers in Windows Device Manager. Try updating the driver manually by selecting "Android Device" -> "ADB Interface" from the list of compatible devices, or use the universal Google USB Driver.
Third-party file transfer and management apps
If standard tools seem complicated or lack functionality, the market offers many alternatives. The leader in this niche is still the app LocalSend or Send Anywhere, which work on the P2P (peer-to-peer) principle and do not require the Internet, only a local network.
Another popular option is to use cloud synchronizers like SyncthingThis solution allows you to create a persistent folder whose contents are automatically updated on your PC and phone in the background. It's ideal for photographers or video makers working with large amounts of data.
It has proven itself to be excellent for screen control. AirDroidIt provides a web interface that not only allows you to view your screen but also receive SMS messages, manage contacts, and take screenshots. The free version has traffic limits, but these are often lifted for local area networks (LAN mode).
| Method | Transfer speed | Difficulty of setup | Functional |
|---|---|---|---|
| FTP (Explorer) | High | Low | Files only |
| Mi Share / HyperConnect | Very high | Low | Files, buffer, screen |
| ADB / Scrcpy | Maximum | High | Full control, debugging |
| AirDroid / LocalSend | Medium/High | Average | Files, notifications, SMS |
Troubleshooting and connection diagnostics
Even with proper setup, issues can still occur. One of the most common problems is the phone not being visible on the network or the connection constantly dropping. This is often due to router settings, particularly the [unclear] function. AP Isolation (access point isolation), which prevents devices within the network from communicating with each other.
Problems can also be caused by a static IP address. If your phone's IP address changes every time you reconnect to Wi-Fi, you'll have to re-enter the IP into ADB commands or client settings. It's recommended to set a static IP for your smartphone in the router or in Android's Wi-Fi settings.
In case of use MIUI Check app permissions in the Security section. The system may block background activity, considering file transfers suspicious. Set the highest priority for sync apps.
If the transfer speed is unexpectedly low, check whether the Wi-Fi channel is congested by neighboring routers. Switching to the 5 GHz frequency usually solves the interference problem and significantly increases the channel throughput.
Wireless connection security
Using wireless methods opens ports for external access. Make sure your Wi-Fi is protected with a strong, industry-standard password. WPA3 or WPA2Using open networks without encryption makes your data vulnerable to interception (Man-in-the-Middle attacks).
When using ADB Always disable Wi-Fi debugging when not in use.
⚠️ Warning: Never agree to requests for RSA debug keys on your phone's screen unless you have initiated a connection from your computer at that time. This may indicate that someone is attempting to access your device.
Update your router and smartphone firmware regularly. Manufacturers Xiaomi Google and Google are constantly patching vulnerabilities in their network stacks, and using up-to-date software is the best defense against exploits.
Why can't the computer see the phone via Wi-Fi, even though both are on the same network?
Most often, the problem lies in the Windows network settings. Make sure the network is marked as "Private." Your antivirus may also be blocking incoming connections. Try temporarily disabling your firewall for diagnostics. If that doesn't help, reboot the router, as the ARP table may be full.
Is it possible to transfer files without installing applications on a PC?
Yes, this is possible via Xiaomi's built-in FTP server (accessible via a browser) or via web versions of services like Snapdrop.net, which operate on the AirDrop principle directly in the browser using the local network.
Does Wi-Fi connection affect phone charging speed?
A Wi-Fi connection itself consumes little power, but when actively transferring large amounts of data, the processor and radio module work intensively, which can cause heat. However, this doesn't directly affect charging speed when using the original charger, although the overall heat generated by the device may slightly slow down the chemical processes in the battery.
Is it safe to use public Wi-Fi to transfer files?
No, it's risky. Protocols like FTP transfer data in cleartext. If you urgently need to do this, use apps with end-to-end encryption or enable a VPN on both devices, although this may significantly reduce speed.
