Wi-Fi Direct on Xiaomi: A Complete Technology Guide

Owners of Xiaomi, Redmi and Poco smartphones often encounter a mysterious feature in wireless network settings that hides the huge potential for fast data transfer. Wi-Fi Direct is a technology that allows devices to connect directly to each other, bypassing the router and access point. This is especially true when you need to quickly transfer gigabytes of photos or launch videos on the big screen without delay.

Many users confuse this mode with the usual modem modem or classic connection over the home network, which leads to a misunderstanding of the principles of operation. In fact, your phone turns into a self-driving router, creating a secure communication channel with another gadget, transfer speeds in this mode can reach 250 Mbps, which is much faster than standard Bluetooth.

In this article, we will take a closer look at how this feature works in the MIUI and HyperOS shell, what are the nuances of connecting to TVs and computers, and how to fix typical connection errors. You will learn why this protocol is often called the “invisible assistant” of media and how to make it work steadily on your device.

Principle of operation and key differences of technology

Wi-Fi Direct is based on IEEE 802.11 standards, but operates on a fundamentally different scheme than the usual Wi-Fi. In the classic scenario, all devices connect to a central node, the router that distributes traffic, and here one device takes the role of an access point (Group Owner), and the second connects to it directly, forming a point-to-point connection.

The main advantage of this approach is that it doesn't depend on external infrastructure. You don't need the Internet, router or mobile. Xiaomi's smartphone itself generates a signal that can be connected to a TV, printer or other phone, which makes data transfer possible even in the field or in places with poor network coverage.

⚠️ Note: When using Wi-Fi Direct actively, the phone’s regular Wi-Fi module may be unstable or switch to frequent network search mode, as the antenna is busy servicing a direct channel.

It's important to understand the difference between this technology and Bluetooth. While both protocols are wireless, Wi-Fi Direct benefits in speed and range. If Bluetooth is ideal for headphones or fitness bracelets, it's simply not suitable for transferring video to 4K or large file archives because of low bandwidth.

💡

Use Wi-Fi Direct to transfer files over 500MB, which will save up to 80% of your time compared to Bluetooth.

How to activate and configure a connection to MIUI and HyperOS

In Xiaomi and Redmi smartphones, the function is often hidden in the back of the menu or activated automatically when compatible applications are launched. For manual control, you need to go to the wireless settings section. The path may vary slightly depending on the firmware version, but the logic remains the same.

Usually, the option is on the Settings → Wi-Fi → Wi-Fi Direct path or in the optional connection menu. In newer versions of HyperOS, the system can hide this item if there are no active devices nearby that support the protocol. So, before searching, turn on the feature on the receiving device, for example, on a Smart TV.

Once activated, the phone will start searching for available devices. The list may not be updated immediately, so you should be patient. If you detect a target gadget, such as an LG or Samsung TV, you will see a pairing request on the screen. You need to confirm the action on both screens to establish a secure connection.

• 📱 Open your Wi-Fi settings on your Xiaomi smartphone.
• 🔍 Click on the menu (three dots or the “More” button) and select Wi-Fi Direct.
• 📺 Turn on Screen Mirroring or AnyCast on your TV.
• 🔗 Select the name of your TV in the list of available devices on your phone.

Use for screen and multimedia broadcasting

One of the most popular Wi-Fi Direct scenes is the transmission of a smartphone image to a large screen, a feature often implemented through Miracast or DLDL protocols, which use a direct connection to transmit a video stream without delay, while the picture quality remains high, since compression is minimal.

To run the broadcast in the notification curtain MIUI often has a ready-made widget "Translation" or "Cast." If not, you can use the standard app "Conductor" or gallery. Select a video or photo, click the button "Translate" and select the target device from the list.

It's worth noting that there may be a slight input lag when streaming games or dynamic video. This is normal for wireless technology, but for competitive shooters, it's better to use a wired connection. However, the delay is completely invisible to watching movies or presentations.

Playback control (pause, volume) is usually available directly from the phone, turning it into a convenient remote control.

Transfer files between Xiaomi devices and other brands

When it comes to file transfer, many people immediately think of MI Share, but it works on top of Wi-Fi Direct and Bluetooth. If you transfer a file to a device of another brand, such as a Windows laptop or a Samsung phone, standard Wi-Fi Direct becomes a universal solution.

You can use embedded system tools or third-party applications that support this protocol to transfer files, and the process is as follows: the sender selects the file, the system creates a temporary network, the recipient connects to it, and the data begins to be transmitted at a high speed.

When you transfer large amounts of data, such as a backup of several gigabytes, the smartphone battery can discharge faster than usual, due to the high load on the radio module, it is recommended to monitor the level of charge or connect the device to a power source.

Compatible with Windows and macOS

Connecting a Xiaomi smartphone to a computer via Wi-Fi Direct offers convenient options for working with files without unnecessary wires. Windows 10/11 has built-in support for the Miracast standard, which makes it easy to broadcast the screen or use the phone as a second monitor.

To set up a connection on a PC, you need to open the Connect app. Once you start, the system will start searching for wireless displays. On the phone in the Wi-Fi Direct or Translation menu, you need to select the name of your computer. After pairing, the smartphone screen will appear in the window on the monitor.

⚠️ Warning: Windows Antivirus or Firewall can block incoming connection. If you have connection problems, temporarily turn off network protection or add the Connection app to exceptions.

With macOS-based devices, things are more complicated because Apple uses its proprietary AirPlay protocol. Direct connectivity through standard Wi-Fi Direct won’t work without third-party software. However, there are AirPlay emulator apps for Android that allow you to “cheat” a Mac and establish a connection.

Typical problems and ways to fix them

Despite the convenience, the technology is not without flaws and can occasionally encounter errors, most often users complain that devices can not see each other or the connection is constantly broken, this can be caused by software failures or physical obstacles.

One of the common causes is conflict. IP-Addresses or network cache overflows, and then resetting the network helps. → Connection and sharing → Reset Wi-Fi, mobile networks and Bluetooth.Please note that this action will remove saved passwords from all Wi-Fi networks.

If your router and devices are operating in a congested 2.4 GHz band, interference from neighbouring networks can interrupt the direct channel. 5 GHz switching (if supported by both devices) often solves the stability problem.

• 🔄 Reboot both devices – it solves 90% of detection problems.
• 📶 Make sure that both devices are on. GPS (Required to run Wi-Fi in Android).
• 🛡️ Check if one of the devices is invisible in the Wi-Fi settings.
• 🔋 Turn off power saving, which may limit the operation of the network module.

If the problem persists, it may be the drivers or firmware version. Check for system updates in the About Phone menu → MIUI version. Xiaomi engineers regularly release patches that fix network stack errors.

💡

The stability of Wi-Fi Direct depends on the relevance of the software and the absence of strong radio interference in the air.
