Smartphones of the series Redmi from the company Xiaomi have long established themselves as reliable devices with wide functionality, however, the owners of the model Redmi Note 7 often encounter difficulties when trying to establish a direct wireless connection between gadgets. Standard shell MIUI has its own navigation features, due to which familiar menu items can be hidden or renamed, which confuses users accustomed to a clean AndroidIn this article, we'll take a detailed look at the process of activating a protocol that allows data transfer without a router.
Understanding how this technology works is essential for quickly transferring large amounts of data when using cloud storage or Bluetooth is impractical due to low speed. Wi-Fi Direct provides significantly higher channel throughput, which is critical when working with 4K video or large archives. We'll cover not only standard enablement methods but also processor-specific nuances. Snapdragon 660, installed in this model.
It's worth noting that the lack of a clear button in the top notification bar doesn't mean the feature isn't working. The system MIUI often hides advanced network settings, relying on the app's automatic device detection Mi Drop or system printing services. Our task is to find ways to force activation and proper pairing of devices in various usage scenarios.
What is Wi-Fi Direct and why is it needed on the Redmi Note 7?
Technology Wi-Fi Direct is a standard that allows two devices to connect directly to each other, without the need for an access point or wireless router. Unlike traditional Wi-Fi, where all devices connect to a central hub, each device can act as either a server or a client. For the owner Redmi Note 7 This opens up the possibility of fast data synchronization even in field conditions where there is no Internet access.
The main advantage is the data transfer speed, which can reach 250 Mbit/s and higher, which is tens of times faster than the classic BluetoothThis makes the technology ideal for transferring high-resolution video files, system backups, or large batches of photos. Furthermore, the connection is secured by the protocol WPA2, which guarantees the security of transmitted information from unauthorized interception.
⚠️ Please note: When connected via Wi-Fi Direct, your smartphone's standard Wi-Fi module may be busy, which will result in a disconnection from your home network or the Internet.
Using this protocol on Redmi Note 7 It also allows you to stream images to compatible TVs and projectors, create local gaming networks for multiplayer, and even print documents on network printers without setting up a complex infrastructure. It's important to understand that this isn't just "accelerated Bluetooth," but a fully-fledged network interface with its own IP address and routing rules.
- 🚀 High data transfer speed, exceeding the capabilities of Bluetooth by 10-20 times.
- 🔒 WPA2 connection encryption to protect your personal information.
- 📡 Ability to connect up to 8 devices into a single local network.
- 🔋 Higher energy efficiency than creating a Wi-Fi Hotspot.
Finding settings in the MIUI shell: where the function is hidden
Owners Redmi Note 7 are often confused because the standard settings menu MIUI There's no separate switch labeled "Wi-Fi Direct." This was intentionally done by the shell developers to simplify the interface. The feature is activated automatically by an app that requires a direct connection, or through hidden system menus. You should start your search from the section Settings → Wi-Fi.
On some firmware versions, especially global ones, you need to access advanced wireless network settings. By clicking the gear icon or the three dots in the corner of the screen, you can find "Additional Features" or "Wi-Fi Settings." This is where the system controls the device's visibility to other devices. If you're using a Chinese firmware version, the path may differ and lead you through the menu. Connections and Sharing.
Please note that the interface may vary depending on the version. Android and layer MIUIIf you can't find the switch using standard methods, try searching through the settings. Enter "Direct" or "Print" in the search bar, as this protocol is often linked to printing or file transfer services.
- 🔍 Use the settings search by entering the keywords "Wi-Fi", "Direct", "Print".
- ⚙️ Check the "Connection and Sharing" section in System Preferences.
- 📱 Please pay attention to Xiaomi apps that may request to enable this feature.
Activation via the Mi Drop app and system services
The easiest and most official way to activate the protocol is Redmi Note 7 - use the pre-installed application Mi Drop (in newer versions it may be called Mi Share). When you launch this app, the system automatically checks for support and activates the necessary wireless modules. You don't need to manually search for switches; simply open the app and click "Send" or "Accept."
On first launch Mi Drop will request permission to use geolocation and Bluetooth. This is a mandatory requirement for the device discovery protocol to work. Once permissions are granted, the smartphone will begin searching for available devices within range. If you see your phone listed on another device, it means Wi-Fi Direct successfully activated in the background.
☑️ Check activation via Mi Drop
Activation can also be done through the print menu. If you try to print a document or photo by selecting "Search for printers," the system will also scan the surrounding area via this protocol. This is a useful lifehack if the main file transfer app isn't working properly. Simply open any photo, click "Print," and select "All Printers" to begin the search.
⚠️ Note: Make sure the screen is turned on and the passcode is unlocked on both devices, otherwise the connection may not be established due to MIUI security reasons.
Using the hidden engineering menu for diagnostics
For advanced users who want to verify the module's functionality or force testing, there is an engineering menu. Redmi Note 7It is accessed through the standard "Phone" application by entering a special code. This menu allows you to check the status of all wireless modules, including Wi-Fi Direct, and see the technical details of the connection.
To enter the diagnostic menu, enter the code ##6484##In the list of tests that opens, find the item related to WLAN or Wi-Fi. Here you can run a module test, check the driver version, and view the connection status. Be careful: changing unknown parameters in this menu may cause instability in your smartphone.
##6484##The engineering menu often provides information about the MAC address and the current chip status. If the Wi-Fi Direct test shows "Failed" or "Error," this may indicate a software error in the drivers or a conflict with installed security updates. In this case, it is recommended to reset the network settings.
Is the engineering menu dangerous?
The diagnostics themselves are safe, but changing the antenna calibration parameters or resetting serial numbers may result in loss of warranty or inoperability of the communication module.
Troubleshooting connection and device visibility issues
Despite the reliability Redmi Note 7, users often encounter a situation where devices cannot see each other. One of the most common causes is a disabled GPS module. The device discovery protocol in MIUI is strictly tied to geolocation, and without GPS enabled, the search simply won't start, even if Wi-Fi is active.
Problems can also arise due to power saving. The system may aggressively "hibernate" the Wi-Fi module in the background to conserve battery. You need to go to the battery settings, find the app you're using to transfer data (for example, Mi Drop or Google Files), and set the background activity limit to "No limit".
Another important aspect is the protocol version. Redmi Note 7 The router supports the 802.11ac standard, but if the second device only operates at 2.4 GHz and uses the older standard, pairing may be slow or error-prone. In such cases, try temporarily disabling 5 GHz mode on the router (if it's being used as a bridge) or on the second device, although this is rarely necessary for a Direct connection.
| Problem | Probable cause | Solution |
|---|---|---|
| The devices don't see each other | GPS is turned off | Enable geolocation in the curtain |
| Low transmission speed | Interference in the 2.4 GHz band | Switch to 5 GHz or change channel |
| Connection break | MIUI power saving | Disable saving for the app |
| Authorization error | Incorrect PIN code | Reset pairing and create a new one |
Alternative applications and delivery methods
If standard means Xiaomi If you are not satisfied with the protocol or it is unstable, you should consider third-party solutions that also use the protocol. Wi-Fi DirectThe leader in this field is the application Google Files (Files from Google), which is often pre-installed on Redmi Note 7It has a built-in "File Sharing" feature that works on the same principle, but with a simpler interface.
Another popular option is Send Anywhere or FeemThese apps create a temporary local network using your smartphone's capabilities. They are especially useful for transferring files between Android And iOS or Windows, where is native Mi Drop may be unavailable. They work on the same principle: one device creates a hotspot, the other connects.
To transfer files to your computer wirelessly, you can use the Wireless Projector feature in Windows 10/11. Redmi Note 7 The PC will see it as an output device and can mirror the screen or transfer files via the Miracast protocol, which is based on Wi-Fi Direct technology. This allows you to quickly transfer photos to the big screen without cables.
