Smartphone owners Xiaomi, Redmi And POCO often encounter a situation where the wireless data transfer function stops responding to commands. Wi-Fi Direct — is a technology that allows devices to exchange data directly, without a router, which is critical for fast file transfers or screen mirroring. However, in the shell MIUI or new HyperOS This module may be hidden, blocked, or not working properly due to software conflicts.
The main difficulty is that the settings interface varies across firmware versions, and the term "Wi-Fi Direct" is often replaced with specific actions like "Broadcast" or "Send." If you're looking for the power button in the menu and can't find it, that doesn't mean the feature is broken. In modern versions of MIUI, there is no separate Wi-Fi Direct switch, since the protocol is activated automatically when supported applications are launched. Understanding this architectural feature helps avoid unnecessary panic and searching for non-existent settings.
Below, we'll examine the technical reasons why the module may be inactive and provide a step-by-step procedure for restoring the connection. You won't need any advanced programming knowledge, but you will need to be careful when checking system permissions.
MIUI architectural features and feature hiding
The first and most common reason for the "absence" of a feature is rooted in the development philosophy. XiaomiThe company's engineers decided to simplify the user interface by removing direct links to Wi-Fi Direct from the standard quick settings menu. The system assumes that the average user shouldn't need to manually manage peer-to-peer connections. Instead, the operating system automatically initiates the necessary protocol when you open the gallery to transfer photos or a screen mirroring app.
This creates the illusion of inoperability. The user tries to find the switch, fails to find it, and concludes that the module is inactive. In reality, Wi-Fi driver It's working properly, but it's in sleep mode, waiting for commands from apps. It only activates when a specific service requests it, saving battery power and reducing processor load.
⚠️ Attention: Attempts to find and enable the hidden engineering menu through codes (##...) on new versions HyperOS These menus may be locked by the manufacturer for security purposes. Do not use third-party apps to unlock system menus, as this may void your warranty.
Additionally, in some firmware regions (for example, European or Russian), the set of system applications differs from the Chinese version. Lack of pre-installed services Mi Share or Mi Drop This may be interpreted as a lack of the protocol itself. Check the list of installed system applications; perhaps a necessary component was previously removed or disabled.
Software conflicts and power saving limitations
shell MIUI is renowned for its aggressive power-saving policy. The system attempts to shut down any background processes it believes are draining battery power. Wi-Fi Direct Requires a constant active connection, which is often considered unnecessary by optimization algorithms. As a result, the system forcibly "kills" the data transfer process, and the function becomes inactive.
To resolve this, you need to manually configure exceptions for system services. Go to battery settings and find the app you plan to use to transfer files (for example, Gallery, File Explorer, or Mi Share). For each app, change the operating mode to "No restrictions." This will prevent the system from disabling the wireless module while it's running.
☑️ Set up power saving for Wi-Fi
It's also worth considering protocol version conflicts. If you're trying to connect a modern Xiaomi With a very old device, the handshake may not work due to differences in security standards. WPA2/WPA3In such cases, the system may simply not show the target device in the list of available devices, creating the appearance of a malfunction.
Diagnostics via the engineering menu and developer mode
For deeper diagnostics, you can use Android's hidden features. Developer mode provides access to logs and settings that are usually hidden. To activate it, quickly tap the build number seven times in the "About phone" section. After doing so, a new option will appear in the advanced settings.
In the "Developer Options" menu, we're interested in network-related options. Here you'll find the "Always enable Wi-Fi when scanning" option or logging settings. Enabling detailed logging will allow you to track when the system blocks a creation request. P2P connections (Peer-to-Peer). This will help determine whether the problem is hardware or software.
| Diagnostic parameter | Where to find | Normal value | Sign of error |
|---|---|---|---|
| Wi-Fi module status | Settings → About phone → All specs | Included | Gray/Inactive |
| Power saving mode | Battery → Settings | Balanced | Ultra/Economy |
| Application permissions | Applications → Rights | All inclusive | Forbidden |
| Driver version | Engineering menu | Current | Unknown/Error |
| Wi-Fi module status | Settings → About phone → All specs | Included | Gray/Inactive |
| Power saving mode | Battery → Settings | Balanced | Ultra/Economy |
| Application permissions | Applications → Rights | All inclusive | Forbidden |
| Driver version | Engineering menu | Current | Unknown/Error |
If you see persistent authorization errors or connection drops in your logs, this may indicate corruption in the network configuration system files. In this case, simply flipping switches won't solve the problem; you'll need to reset your network settings.
What is P2P in the context of Wi-Fi?
P2P (Peer-to-Peer) is a technology for direct connections between devices without an access point. In Android, this is implemented via Wi-Fi Direct. When a phone searches for devices to transfer files to, it scans the airwaves using P2P mode. If this service is blocked by the system, the search will return no results.
Reset network settings and reconnect
Often, a complete network reset resolves the issue. This will delete all saved Wi-Fi passwords, Bluetooth settings, and mobile hotspots, but will return the network stack to its original state. Xiaomi the path usually looks like this: Settings → Connection and sharing → Reset Wi-Fi, mobile networks, and Bluetooth.
After resetting, you'll need to re-authenticate with your network. It's important to check if you have a third-party Wi-Fi management app or antivirus software with a "Network Protection" feature installed. Such programs can hijack the module and block direct connections, considering them potentially dangerous.
If the problem persists after the reset, try changing the device name. Some older devices don't recognize phones with certain characters in the name or with very long names. Rename the phone to Settings → About phone → Device name, using only Latin letters.
⚠️ Attention: Before resetting your network settings, make sure you remember the passwords for important Wi-Fi networks, as it will be impossible to restore them from the system after the procedure.
Alternative methods of transfer and mirroring
If classic Wi-Fi Direct If it doesn't work for your purposes, consider alternatives built into the ecosystem. Xiaomi. Technology Mi Share (previously Mi Drop) uses the same protocol but has its own interface and optimizations. It allows you to transfer files to other phones. Xiaomi and high-speed laptops.
To display an image on a TV, instead of searching for a display directly via Wi-Fi Direct, it's better to use the built-in "Broadcast" function. It's based on protocols Miracast And DLNA, which also work over Wi-Fi but require less manual configuration. Simply swipe down from the top corner of the screen to open the control center and select the "Cast" icon.
If you need direct transfer to a device of another brand, try third-party file managers such as Send Anywhere or Files by GoogleThey create their own access point or use QR codes to initiate connections, which often bypasses software blocking the shell.
Wi-Fi module hardware failure
Physical damage also cannot be ruled out. If the Wi-Fi module is damaged (for example, after being dropped or exposed to water), it may operate in a limited mode: it may connect to the router but not support access point or direct connection modes. This is because different operating modes use different frequencies and signal modulation algorithms.
You can check this by starting your device in safe mode. If the function starts working in safe mode (starting with the power button held down), then an app you installed is causing the conflict. If it works in safe mode too Wi-Fi Direct is not active, and resetting the settings did not help, there is a high probability of a hardware failure of the antenna module or cable.
In such cases, software methods are ineffective. Diagnostics at a service center are required, where specialized equipment will be used to check the integrity of the motherboard circuits and the operation of the radio module.
Why did I lose the ability to transfer files after updating MIUI?
Updates often change security policies. The new version may require re-approval of system app permissions. Go to app settings and re-apply Wi-Fi and Bluetooth permissions for Gallery and File Explorer.
Is it possible to enable Wi-Fi Direct via ADB commands?
Theoretically yes, using commands like adb shell wm size or specific intents, but on modern versions of Android, this requires root access. Without root access, the system will block the command to change the Wi-Fi P2P state.
Does a case affect Wi-Fi Direct?
Yes, metal or magnetic cases can block the signal, especially at 5 GHz frequencies, which are often used for high-speed Direct mode transmissions. Remove the case to check the connection quality.
Why does the phone see the TV but not connect?
Often, the problem lies in different frequency bands. If your phone operates on a 5 GHz network but your TV only supports 2.4 GHz (or vice versa), a direct connection may fail. Make sure both devices support the same standard, or use the router as a bridge.
