Step-by-step instructions for activating the connection
The inclusion process Wi-Fi Direct on Redmi 9 It's most often initiated by user action rather than a static setting. To initiate a transfer, open the file you want to send and select "Send" or "Share." The system will automatically search for nearby devices using the desired protocol.
Let's look at the steps for manually setting up a connection to a printer or TV. First, make sure Wi-Fi is enabled on both devices. Then, on the Redmi 9, go to Settings → Connection and SharingIn some versions of MIUI, there may be a "Cast" or "Wireless Monitor" option here, which launches a search for compatible devices via Direct.
☑️ Activation algorithm
If you're connecting to a PC, the process may be different. You'll need an intermediary app, such as Mi Drop (now known as ShareMe) or a third-party equivalent. Once the app is launched, the phone will create a hotspot, which the computer will then need to connect to. This is how Direct technology is implemented in the Xiaomi ecosystem.
- 📂 Open the file in your gallery or file manager.
- 📤 Click the "Share" button.
- 📡 Select "Wi-Fi Direct" or find the device in the "Nearby" list.
- ✅ Accept the pairing request on the receiving device.
Transfer files via built-in apps and ShareMe
The most convenient way to use Wi-Fi Direct on Xiaomi Redmi 9 - this is the use of a proprietary application ShareMe (formerly Mi Drop). It's specially optimized for MIUI and uses the Direct protocol to achieve maximum speeds. This eliminates the need to dig through hidden settings menus.
To get started, open the app and tap the "Send" or "Receive" button. The app will request permission to use location and Wi-Fi, which is necessary for scanning your surroundings. After this, your phone will become visible to other devices running ShareMe or supporting the standard transfer protocol.
When transferring files to devices from other brands (Samsung, Huawei), the technology also works reliably, provided they have compatible apps installed. Transfer speeds can vary depending on distance and interference, but typically range from 10 to 40 MB/s, allowing you to transfer a movie in a couple of minutes.
Connecting to peripheral devices and TV
Functional Wi-Fi Direct on Redmi 9 It's not limited to smartphones. This technology is widely used to connect to printers, projectors, and Smart TVs. For example, many modern printers allow you to print photos directly from your phone without installing drivers or connecting to a network.
The "Cast" or "Broadcast" function is often used to connect to a TV. In this case, the phone acts as a remote control or signal source. Make sure your TV supports Miracast or similar standards based on Wi-Fi Direct technology. The pairing process usually takes less than a minute.
| Device type | Connection method | Required software | Transfer speed |
|---|---|---|---|
| Smartphone (Android) | ShareMe / Quick Share | Built into the system | High (up to 40 MB/s) |
| iPhone (iOS) | Not directly supported* | Trebleit (iOS) | Low / None |
| Printer | Printing via Wi-Fi Direct | Print plugin | Average |
| Smart TV | Screencasting (Cast) | Mi TV / Chromecast | Depends on the router |
*Note: Apple uses its own AirDrop protocol, which isn't directly compatible with Android Wi-Fi Direct, although the technologies are similar. Transfers between iOS and Android require special intermediary apps.
Solution: Connection and speed issues
Despite the reliability of the technology, users Redmi 9 may encounter difficulties. Often, the device doesn't recognize the partner device, or the connection constantly drops. One common cause is the enabled power saving mode, which aggressively limits Wi-Fi activity in the background.
Problems can also arise due to frequency band congestion. If there are many 2.4 GHz networks nearby, the signal may be unstable. In this case, it's worth trying switching to 5 GHz if both devices support it, or simply changing the channel in the router settings, although this is less relevant for Direct.
⚠️ Attention: If file transfers are constantly interrupted at 99%, check the receiving device for available space. Also, make sure the phone's screen doesn't turn off during the transfer (set the screen timeout to "Never" during the transfer).
For diagnostic purposes, you can reset your network settings. This will return all Wi-Fi, Bluetooth, and mobile network settings to factory defaults. Xiaomi This is done through the menu Settings → Connection and sharing → Reset Wi-Fi, mobile networks, and Bluetooth.
