Faced with the inability to transfer a file or display an image, users often find that the WiFi Direct feature on their Xiaomi device is simply inactive. This is a common problem that can hide both software conflicts and the features of the MIUI shell. Unlike standard Bluetooth, this protocol provides high-speed data transfer without the need for a router, creating a direct communication between gadgets.
However, if the button in the menu is gray or option is missing, the system blocks the connection. Often the cause is background processes that “capture” the wireless module, or outdated network settings. It is important to understand that Xiaomi uses aggressive battery optimization, which can forcefully disable energy-intensive radio functions to save charge.
In this article, we will discuss in detail all possible causes of blocking the function and offer step-by-step solutions, you will learn how to reset network settings correctly, check driver compatibility and avoid common configuration errors. The key factor is often conflicting versions of the security protocol. WPA2/WPA3, which requires manual intervention in the settings of the router or phone.
The impact of the MIUI shell on the operation of wireless modules
MIUI has deep system limitations that directly affect the availability of WiFi Direct. Engineers implement strict power regulations that can automatically turn off a Wi-Fi module if it is not used to access the Internet. This often causes the file transfer feature to become unavailable at the most inopportune time.
In addition, embedded antivirus and Optimizer may perceive attempts to create a direct connection as a potential security threat.The system blocks connection requests if the application that initiates the transfer does not have the appropriate permissions or is signed with an unknown certificate.
It is also worth considering that in different versions of firmware (Global, China, EU) The settings and logic of the modules may differ. In some assemblies, the function may be hidden in the engineering menu or require activation through the ADB-team.
💡
Use No Limits mode in battery settings for applications that are constantly using WiFi Direct so that the system doesn’t “kill” the transfer process.
The main reasons for blocking the function on the smartphone
There are a number of technical reasons why WiFi Direct can be deactivated at the system level, most often because other network services occupying the antenna module are simultaneously operating, such as an active modem or Wi-Fi Internet distribution, which can block the possibility of creating a direct communication channel.
Another common cause is malfunctioning of Android network services. wpa_supplicant Or errors in the network cache make the phone forget how to initiate a connection, in which case, standard on and off aeronautical mode often does not help.
Hardware limitations of older models can also be ruled out: Some Xiaomi budget devices are equipped with single-threaded Wi-Fi modules that cannot physically simultaneously connect to the router and operate in Direct mode.
Step-by-step instructions for activation through settings
To return to the functionality, you need to perform a sequential reset of network settings. Don't rush to completely reset your phone right away, start with softer methods. Go to Settings, then select Connection and Sharing or Additional settings depending on the version of MIUI.
Find Wi-Fi, mobile and Bluetooth Reset. Click on it and confirm the action. This will remove all saved passwords and pairings, but often solves the problem of hanging network services. After the reboot, try activating the function again.
If the standard path doesn't work, you can try activating the hidden menu, and in the Phone app, dial ##6484## to log into the engineering menu, where you can check the status of the Wi-Fi module and start testing.

Application and third-party software conflicts
Often, the reason WiFi Direct is not active is because of third-party file transfer applications or download managers, which can take control of the module and not give it back to the system, especially for applications that require root rights or deep integration into the system.
Check the list of newly installed programs. If a problem occurs after installing new software, try to remove it, and look for antivirus programs that can block direct connections between devices, considering them unsafe.
In some cases, cleaning the data from the Settings system application helps. Go to Settings → Apps → All Apps, find Settings, click Clear and select Clear All. This will return system settings to factory values without losing personal data.
⚠️ Warning: Cleaning up system applications data can reset your personalizations such as wallpaper, widget layout and alarm settings.Be prepared to restore them manually.
Compatibility table and frequent errors
Below is a table that will help you identify the typical symptoms and their possible causes, which will speed up the diagnosis of the problem on your Xiaomi, Redmi or Poco device.
| Symptoms. | Probable cause | Method of decision |
|---|---|---|
| The button is grey and not pressed. | Energy saving regime | Turn off energy savings |
| The device does not see other gadgets | Different frequencies (2.4/5 GHz) | Switch frequency in router settings |
| Error of connection when trying | Conflict IP-address | Resetting network settings |
| The function disappeared from the menu | System process failure | Resetting or resetting settings |
Technical details of the protocol
Use of alternative methods of transmission
If the built-in tools have failed to activate WiFi Direct, it’s worth considering alternatives. There are many apps in the Android ecosystem that use their own implementations of the protocol, bypassing system constraints, such as Send Anywhere or Feem creating a local network differently than the standard Android feature.
You can also use the “Mi Drop” feature (now part of Xiaomi Share), which is optimized specifically for Xiaomi devices and often works more stable than the standard Android protocol, and you can use the built-in “Sharing with Environment” feature to transfer files to other brands.
For advanced users, the ADB (Android Debug Bridge) method is available, and the command line can force the service to run or change the configuration files that run the Wi-Fi module, but this method requires a PC and command line skills.
💡
If standard WiFi Direct doesn’t work, analog apps like Xiaomi Share often solve the problem of transferring files even faster and more stable.
Prevention and Update of Software
Regular firmware updates are the best way to avoid software errors. Each MIUI update contains security patches and fixes for wireless drivers. Check for updates in the About Phone section and install the latest version available.
Also keep an eye out for updates to system components through the Google Play Store. Google Play services often update network security and connectivity modules, and ignoring these updates can lead to incompatibility with new devices.
Reboot your smartphone periodically, freeing up RAM and restarting all system services, including those that run the network connections, and running long hours without rebooting can lead to cache errors.

Is it safe to use WiFi Direct in public places?
Does the case affect the operation of WiFi Direct?
⚠️ Note: When resetting network settings through an engineering menu or ADB-Make sure you know the passwords from your Wi-Fi networks, as they will be deleted without the possibility of recovery.
In conclusion, the problem with inactive WiFi Direct on Xiaomi is most often solved by software methods. Proper setting of permissions, reset network settings and software updates allow you to restore functionality in 90% of cases. If none of the methods helped, there may be a hardware malfunction of the Wi-Fi module, which will require contacting the service center.
