Modern Xiaomi and Redmi smartphones offer a wide range of features, often hidden deep within system settings. One such technology is Wi-Fi Direct, which allows you to transfer files and stream images directly between devices without a router. Many users wonder where to find this feature, as there's often no obvious "Enable" button in the standard menu.
Unlike regular Bluetooth, this protocol provides much higher data transfer rates, which is critical for streaming 4K video or quickly transferring gigabytes of data. However, to take full advantage of this technology, you need to understand the specifics of the MIUI or HyperOS interface. In this article, we'll cover in detail how to activate the mode, the nuances of connecting to different types of equipment, and how to resolve common connection issues.
It's worth noting that on Xiaomi devices, the activation process often occurs automatically when attempting to connect to a compatible device. However, there are hidden engineering menus and dedicated apps that allow for more flexible connection management. Understanding these mechanisms will help you avoid errors and establish a stable connection in minutes.
What is Wi-Fi Direct and why is it needed on Xiaomi smartphones?
Wi-Fi Direct Xiaomi is a wireless communication standard that allows devices to connect directly to each other, bypassing an access point or router. Unlike traditional Wi-Fi, where all devices rely on a central router, Xiaomi smartphones become the network's hub or connect to other devices as peers. This opens up the possibility of transferring files at incredible speeds, unachievable with Bluetooth.
The technology's main advantage is speed and range. While Bluetooth is limited to a few megabits per second, a direct Wi-Fi connection can reach speeds of hundreds of megabits per second, comparable to a wired connection. This makes the technology ideal for transferring large amounts of data, such as movies, photo gallery backups, or even system images.
In addition to file transfer, the protocol is actively used for multimedia. Function Miracast Screen mirroring to a TV is often based on this standard. The smartphone creates a video stream and sends it directly to the receiver, ensuring minimal latency. This is especially useful for gaming or watching online movies on a big screen without loss of quality.
It's important to understand that internet access is not required for operation. Even if your mobile data is disabled or you don't have access to your home network, data transfer between the two devices will work reliably. This makes the technology indispensable when traveling or in offices where corporate networks may block file sharing between employees.
- 🚀 High data transfer speed, significantly exceeding the capabilities of Bluetooth.
- 📡 Ability to connect multiple devices simultaneously to a single network.
- 🔒 WPA2 encryption ensures protection of transmitted information from interception.
- 📱 No need for a router or internet access.
Despite its obvious advantages, the technology has its own implementation quirks within the MIUI interface. The system strives to conserve battery life, so background services may limit the module's activity. It's important for the user to know how to properly initiate a connection to prevent the system from terminating the transfer process at the most inopportune moment.
Where to find Wi-Fi Direct settings in MIUI and HyperOS
Search settings Wi-Fi Direct On Xiaomi smartphones, enabling this feature can be a real quest, as manufacturers have deliberately hidden it from the average user. You won't find a dedicated toggle in the standard "Settings" menu. This is done to simplify the interface: the system logic assumes that the feature is activated automatically when you select "Broadcast" or "Send via Wi-Fi" in a compatible app's menu.
However, access to connection management does exist. It's usually hidden in the settings menu of the wireless module itself. To access it, go to Settings → Wi-FiHere, in the upper right corner of the screen, you'll usually find a menu with three dots or an icon for additional settings. This is where you might find the option for advanced wireless features.
However, on new firmware versions HyperOS This option is often missing in recent MIUI updates. In such cases, the system relies on Google and Xiaomi service frameworks. Activation occurs contextually: when you launch a file transfer app (such as Mi Drop or Send Anywhere), the system automatically enables the required module. Manual activation is rarely required and is mainly for specific tasks, such as connecting to older printers or industrial equipment.
⚠️ Attention: Leaving device scanning enabled in the background can significantly increase battery consumption. It's recommended to only enable this feature when transferring data or connecting to an external display.
If you can't find the settings using standard methods, you can use the settings search. Enter "Direct" or "Broadcast" in the search bar at the top of the settings menu. The system will automatically prompt you to navigate to the desired section or launch the appropriate service. This is the fastest way to access the desired menu, avoiding complex paths.
It's also worth keeping in mind that the menu layout may differ depending on the regional firmware version (Global, China, EEA). In Chinese versions of the shell, some system apps responsible for wireless transmission may be removed or replaced with local equivalents, which changes the menu structure.
Connecting a Xiaomi smartphone to a TV via Wi-Fi Direct
One of the most popular use cases for this technology is displaying images on a large screen. TVs that support Smart TV Miracast or WiDi protocols are often used, which are based on the principles of direct connection. To begin the process, make sure both devices are a smartphone. Xiaomi and the TV are in the ready-to-connect mode.
You need to activate the signal reception function on your TV. Depending on the brand (Samsung, LG, Sony), this may be called "Screen Mirroring," "Cast," "MirrorShare," or simply "Wi-Fi Direct." Once enabled, the TV will begin searching for available devices. On your smartphone, open the notification shade and find the "Cast" option. If this option isn't there, you can add it by editing the quick actions list.
After activating the search, your phone will begin scanning the airwaves. When your TV's name appears in the list, tap it. A connection confirmation prompt may appear on the TV screen; accept it using the remote. From this point on, your smartphone's screen will be mirrored on the TV. Picture quality depends on the strength of your Wi-Fi module and interference in the airwaves.
If automatic connection does not occur, try using third-party aggregator apps such as Web Video Caster or TV CastThey often have more advanced search algorithms and can "wake up" a dormant Wi-Fi Direct module on a TV, forcibly initiating the handshake process.
⚠️ Attention: TV interfaces and MIUI versions are constantly updated. Menu item names may differ from those described. If you don't find an exact match, look for synonyms related to "Cast" or "Screen."
For stable operation, it's recommended that devices support the 5 GHz standard. In congested apartment buildings, the 2.4 GHz band can become overwhelmed by neighboring signals, resulting in artifacts on the screen or audio desync. You can check the supported frequencies in the specifications of your router or TV.
Transferring files between devices: Mi Drop and other methods
For sharing documents, photos, and videos between Xiaomi smartphones and other Android devices, the most effective tool is the built-in app Mi Drop (in global versions it may be called ShareMe). This app uses Wi-Fi Direct to create a high-speed connection. Unlike Bluetooth, it eliminates the need for pairing and entering confirmation codes for each transfer.
The transfer process is simple: the sender opens the file, selects "Send," and searches for the recipient in the Mi Drop list. The receiving device must have the app running and the screen turned on. Transfer speeds can reach 20-40 MB/s, allowing you to transfer a 1 GB movie in under a minute. This is especially convenient when you need to quickly transfer a photo archive from one phone to another.
A key advantage is its cross-platform support. Although Mi Drop is designed for the Xiaomi ecosystem, the app is available for installation on any Android smartphone and even has a web version for PCs. When transferring to an iPhone or other devices, the app automatically creates an access point for the recipient to connect to, emulating Wi-Fi Direct.
☑️ Check before transferring files
There are also alternative methods that don't require installing additional software. Some file managers, such as Xiaomi's built-in File Explorer, have a "Cleanup" or "Transfer" feature that also enables the direct channel. However, specialized apps often perform more reliably and offer a more user-friendly interface for transfer history.
When transferring large amounts of data, monitor the device's temperature. Active Wi-Fi operation at high speeds causes the processor and radio module to heat up. If the phone overheats, the system may artificially reduce the transfer speed or even terminate the connection to protect components.
Using Wi-Fi Direct to Print Documents
Modern printers from HP, Canon, Epson, and Samsung often feature direct printing. This allows you to print documents directly from your smartphone. Xiaomi, even if the printer is not connected to your home Wi-Fi network. This is done using the Wi-Fi Direct, built into the printing device. In this case, the printer acts as an access point or client.
To set up printing, you first need to activate the function on the printer itself. This is usually accomplished by a button on the device's panel with a smartphone image or a Wi-Fi icon. Once activated, the printer will create a network with a name that includes the device model (e.g., "DIRECT-HP-DeskJet"). The connection password is often printed on a sticker on the printer's body or displayed on the printer's screen.
Next, on your Xiaomi smartphone, follow these steps: go to Wi-Fi settings, find your printer's network, and connect to it. Once connected, download the manufacturer's official app (e.g., HP Smart, Epson iPrint or Canon PRINT). The application will automatically detect the printer on the local network (which in this case is a direct connection) and offer to set up printing.
| Printer brand | Recommended app | Connection Features |
|---|---|---|
| HP | HP Smart | Automatic setup, AirPrint support |
| Canon | Canon PRINT Inkjet/SELPHY | Manual Wi-Fi switching on the phone is required. |
| Epson | Epson iPrint | Support for printing photos and documents |
| Samsung | Samsung Mobile Print | Also works with printers of other brands |
Some modern Xiaomi smartphones support dual-band operation, but in Direct mode, printing is prioritized. Internet access will then require mobile data.
⚠️ Attention: When connecting to a printer via Wi-Fi Direct, your phone may warn you that "There is no internet connection." Don't ignore this warning if you need access to cloud services for printing, but confirm the connection to complete the setup.
If the printer supports the technology Wi-Fi Direct Secure, the connection process will be even more secure. In this case, pairing may require entering a dynamically generated PIN or specified in the instructions. This prevents unauthorized devices from connecting to your printer in public places.
Solution: Why the connection isn't working
Despite the well-established technology, users often encounter problems when trying to turn on Wi-Fi Direct or connect to a device. The most common cause is frequency conflicts. If one device only operates in the 2.4 GHz band and the other is configured for 5 GHz, they may simply not "see" each other. Try adjusting the router or access point settings (if possible) to match the frequency of both devices.
The second common issue is MIUI's aggressive power saving. The system can "kill" the background device search process, considering it an unnecessary resource consumer. To avoid this, go to battery settings, find the app that's connecting (for example, Mi Drop or the printer app), and set the power saving mode to "No restrictions." This will give the process the green light.
It's also worth checking your location permissions. In Android 6 and higher, the Wi-Fi scanner (which searches for Direct devices) requires location access and permission for the app to access location. Without this permission, the search button may simply spin the loading bar and find nothing.
Hidden commands for diagnostics
In some cases, resetting your network settings can help. Go to Settings → Connection & Sharing → Reset Wi-Fi, Mobile Networks, and Bluetooth. This won't delete your personal data, but it will return your network settings to factory defaults, which often resolves stuck connection issues.
If all else fails, try temporarily disabling VPN services or antivirus software. They may block local traffic, considering it suspicious, especially if the connection doesn't connect to the global network. Disabling security mechanisms during setup often helps diagnose the problem.
In rare cases, the problem lies with a static IP address. Make sure your current network's Wi-Fi settings are set to obtain an IP address via DHCP. Manually assigning addresses can cause conflicts if the device addresses are outside the same subnet or have the same address.
Frequently Asked Questions (FAQ)
Is it safe to transfer banking information via Wi-Fi Direct?
Using Wi-Fi Direct for file transfer is secure because the connection is encrypted. However, sharing map screenshots or passwords via open files is not recommended. The protocol protects against external interception, but does not guarantee security on the receiving device if it is infected with a virus.
Why does file transfer speed drop after a while?
Speed may drop due to heating of the Wi-Fi modules. The smartphone reduces its transmitting power to cool down. Interference from other Wi-Fi networks and Bluetooth devices operating in the same frequency range can also affect speed.
Is it possible to play online games via Wi-Fi Direct?
No, Wi-Fi Direct creates a local network between devices without internet access. You can only play local multiplayer games that support LAN mode, but you won't have access to online game servers.
Does Wi-Fi Direct work if the smartphone screen is off?
In most cases, no. Xiaomi's system may disconnect or pause the transfer when the screen is turned off to save power. For long-term file transfers, it's best to keep the screen on or configure tapping.
