Understanding how this technology works will help you manage the data on your device more effectively. Xiaomi.
In this article, we'll take a detailed look at the activation process, possible hidden settings, and solutions to common issues users encounter. You'll learn how to make your phone visible to other devices and what alternatives the ecosystem offers. MIUI for quick file sharing.
What is Wi-Fi Direct and why is it needed on the Redmi 9?
Wi-Fi Direct — is a wireless communication standard that allows two devices to connect directly to each other, bypassing the need for an access point or router. Unlike regular Wi-Fi, where all devices connect to a router, here one of the devices (for example, your Redmi 9) takes on the role of connection coordinator. This creates a high-bandwidth local network.
The main advantage of this technology is speed. 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. The protocol uses 2.4 GHz and 5 GHz frequencies, providing a stable channel for transmitting large amounts of data without quality compression. This makes the technology ideal for streaming video to a TV or quickly transferring files between phones.
On devices Xiaomi This feature is often integrated into system file transfer services, but can also be used by third-party apps for specific tasks, such as printing documents or connecting to smart devices. It's important to understand that during an active connection, battery consumption may be higher than usual, as the radio module operates in high-power mode.
- 🚀 High data transfer speed, tens of times higher than Bluetooth.
- 🔒 Secure connection using WPA2 encryption.
- 📱 Possibility of connecting peripherals without a router.
- 🔄 Simultaneous work with the Internet (on some models).
⚠️ Attention: When using Wi-Fi Direct in hotspot mode, mobile Internet on the receiving device may become unavailable, since the Wi-Fi module will be busy servicing the direct communication channel.
Where to find the Wi-Fi Direct setting in MIUI
Users migrating from other brands or older versions of Android often have difficulty finding the menu item. In the shell MIUI, installed on Redmi 9The developers have hidden the explicit toggle switch in the main Wi-Fi settings. This is to simplify the interface, as the system automatically handles most detection processes.
However, access to these features remains. They've been moved to deeper menus or replaced with proprietary Xiaomi solutions. Checking the status or changing visibility settings sometimes requires using the engineering menu or third-party utilities, although basic file transfers are suffice using standard system tools. The standard path Settings → Wi-Fi most often does not contain the switch you are looking for.
It's worth noting that the lack of a visible button doesn't mean the feature isn't working. The system automatically activates Direct mode when you launch a compatible app or attempt to send a file. If you need to force the mode for debugging or specific tasks, you'll have to use hidden methods.
To access advanced network settings, you can try entering a special code in the Phone app. For example, the code ##6484## Opens the engineering menu, where you can test the operation of communication modules. However, be careful: changing unknown parameters may disrupt network stability.
Step-by-step instructions for activating the function
Since there's no direct button in the menu, activation occurs through system sharing services. The most reliable way to "enable" visibility for Direct connections is to activate Xiaomi's file transfer services or use the standard file manager. Let's look at the steps for Redmi 9.
First, you need to make sure that the wireless module is active. Go to Settings and select a section Wi-FiMake sure the slider is turned on, even if you're not connected to any networks. Next, go to the module's settings by clicking the arrow or gear icon in the upper right corner of the screen.
☑️ Pre-activation check
The next step is to start the search process. Depending on the version MIUI, you may need to select "Wi-Fi Settings" or "Advanced Settings."

⚠️ Note: The settings interface may differ depending on the firmware version (Global, China, Russia). If you don't find the item in the specified location, try updating the system or using the settings search.
If activation fails using standard methods, you can use third-party apps from Google Play that force Direct mode. They request the necessary permissions and programmatically switch the module's state. However, for everyday use, this is rarely necessary, as native tools Xiaomi work stably.
Using Mi Share for quick sharing
In the ecosystem Xiaomi The main tool that replaces the classic Wi-Fi Direct for the user is the function Mi ShareIt's similar to Apple's AirDrop, which uses a combination of Bluetooth for searching and Wi-Fi Direct for data transfer. Redmi 9 This is the most efficient way to share files.
To use Mi Share, pull down the notification shade and find the corresponding icon. Make sure it's active. When sending a file from the gallery or file explorer, select "Send" and then "Mi Share." Your phone will begin searching for nearby devices. It's important that the receiving device (even if it's not a Xiaomi) also has the corresponding service or app enabled.
The advantage of this method is its automation. You don't need to manually enter passwords or search for available networks. Protocol It will automatically negotiate connection parameters and start transferring at the maximum possible speed. Devices from other brands, such as OPPO or Realme, may require installing a plugin for compatibility.
Secrets of Mi Share
The feature uses Bluetooth Low Energy to continuously scan the surroundings, minimizing battery drain in standby mode. When a transmission begins, the powerful Wi-Fi module is instantly activated.
If you are trying to connect Redmi 9 When connecting to a printer or TV that doesn't support Mi Share, the system automatically switches to compatibility mode using standard discovery protocols. This ensures universal connection to various peripherals without manually configuring IP addresses.
Setting up connection visibility and security
Security is critical when using direct connections. When your Redmi 9 When your phone becomes visible to others, it's important to control who can initiate a connection. In Mi Share settings, you can choose who can see your phone: everyone, contacts only, or no one.
It is recommended to set the restriction "Contacts only" or "Visible for 10 minutes" to prevent unauthorized attempts to transfer files from strangers in public places. The system MIUI always asks for confirmation on the screen when an incoming transfer request is received, which is an additional barrier.
| Parameter | Description | Recommendation |
|---|---|---|
| Device name | The name visible in the list of networks | Change to unique |
| Visibility | Who can detect the phone? | Contacts only |
| Encryption | Type of transmission channel protection | WPA2 (automatic) |
| Auto-reception | Automatic file acceptance | Off |
It's also worth paying attention to the device name. By default, it may be called "Redmi 9" or contain a serial number. Change it to something recognizable in the menu. Settings → About phone → Device nameThis will help you easily identify your gadget in the list of available networks when connecting to a printer or TV.
Troubleshooting connection issues
Despite the technology's robustness, users may encounter errors. A common issue is when a phone doesn't detect other devices, or vice versa. First, make sure Bluetooth and Wi-Fi are enabled on both devices. Even if you're not using Bluetooth for data transfer, it's required for the initial handshake.
If devices are found but the connection is lost, try rebooting the communication module. Turn on airplane mode for 10 seconds and then turn it off. This will reset the network stacks and update the IP addresses. Also, check if any of the devices have traffic or background activity restrictions for the app used for the transfer.
Another common issue is low speed. This can occur if one device is operating in the 2.4 GHz band while the other is trying to use 5 GHz, or if the channel is heavily congested with neighboring routers. In this case, the system may automatically switch to a lower speed for stability.
- 📶 Make sure the distance between devices does not exceed 5-10 meters.
- 🔄 Restart both smartphones if connection errors persist.
- 🛡️ Check permissions for the Security app and system services.
- 📱 Update the firmware to the latest version via the update menu.
