Modern smart TVs from the company Xiaomi Equipped with a wide range of wireless interfaces, allowing you to stream content without unnecessary wires, many users, when trying to set up screen mirroring of a smartphone or tablet, look for the function in the settings menu. Wi-Fi DirectThis is a standard technology that allows devices to connect directly, bypassing a router. However, set-top box owners Android TV often encounter a puzzling situation: a familiar menu item is simply not available.
This is not a device malfunction. The problem is with the operating system. Android TV, on which the models are based Mi Box And Mi TV Stick, uses more advanced protocols for multimedia transmission. Instead of the classic Wi-Fi Direct, it implements technologies Miracast And Google Cast, which functionally overlap with the capabilities of a direct connection but require a different approach to setup. You don't need to search for hidden menus; simply understand the ecosystem's logic. Google.
In this article, we will take a detailed look at why the Wi-Fi Direct interface is hidden or missing on devices. Xiaomi, and what tools to use to achieve the same goal. You'll learn how to set up wireless image and audio streaming using built-in system tools and third-party apps. This will allow you to enjoy content from your mobile devices on the big screen without lag or loss of quality.
Differences between the Android TV interface and classic Smart TVs
To understand where to look for the necessary settings, it is necessary to understand the architectural differences between operating systems. Traditional Smart TV at the base Tizen or WebOS often have a dedicated menu item for Wi-Fi Direct, as this is used for initial pairing of remotes or keyboards. In the environment Android TV Priority is given to network protocols running over the local network.
System Xiaomi optimized for working in conjunction with services Google. Here Wi-Fi Direct often runs in the background to ensure the function works Google CastWhen you press the broadcast button in the app YouTube or NetflixThe device uses a direct communication channel, but the user does not need to manually activate it in the settings. This is done to simplify the user experience.
⚠️ Warning: Attempting to install third-party Wi-Fi Direct emulation apps from unknown sources may result in system instability. Use only verified tools from the official store. Google Play on TV.
It's important to note that the absence of a visible switch does not mean the module is disabled. TV antenna Xiaomi It constantly scans the airwaves and is ready to accept connection requests. The only difference is that this process is fully automated. Manual intervention is required extremely rarely and only in specific peripheral usage scenarios.
Wi-Fi Direct Alternatives: Miracast and Google Cast
Since direct access to Wi-Fi Direct limited, the main tools for wireless image transmission are technologies Miracast And Chromecast built-in. The first technology, also known as Wireless monitor, allows you to mirror your smartphone's screen to your TV in real time. This is ideal for sharing presentations, photos, or web pages.
Technology Google Cast It works differently: it doesn't simply mirror the screen, but streams the video directly from the server to the TV. This reduces the load on the smartphone and ensures higher picture quality. For both methods to work, the TV and mobile device must be on the same network or use line-of-sight mode, which is activated automatically when attempting to connect.
To activate these features on your TV Xiaomi Usually, no deep configuration is required. It is enough to make sure that the module Wi-Fi enabled. The system will automatically detect the incoming connection type and select the optimal protocol. The user only needs to confirm the request on the TV screen or select the device from the smartphone menu.
Wireless connection setup instructions
The process of setting up image broadcasting on Xiaomi TV The TV is as simplified as possible. You don't need to search through complicated menus; all the necessary functions are available on the home screen or in quick settings. First, make sure your TV is connected to your home Wi-Fi network. This is a prerequisite for most data transfer protocols to work.
Next, you need to activate discovery mode. On the remote control, find the button with the house icon or the app icon. In the list of pre-installed system apps, find the item Wireless monitor or CastLaunching this application puts the TV into connection standby mode.
☑️ Checking connection readiness
Now pick up your smartphone. If you have a device based on Android, pull down the notification shade and find the button Broadcast, Smart View or ProjectionYour TV should appear in the list of available devices. XiaomiClick on it and after a few seconds the image will appear on the screen.
In some cases, the system may ask for confirmation. A code or permission request will appear on the TV screen. Use the remote control to confirm. The connection will then be established, and you can control the content from your smartphone.
Using third-party applications to transfer data
If the system's standard tools don't work for some reason or don't support the file format you need, third-party solutions can help. Google Play on TV Xiaomi offers a variety of applications that implement their own transmission protocols similar to Wi-Fi DirectThey create a local access point or use DLNA.
One of the most popular solutions is the application AirScreenIt emulates a receiver. AirPlay, Google Cast And Miracast simultaneously. After installation and launch, the app provides clear connection instructions. This is especially useful for older smartphone models that don't recognize the TV using standard tools.
| Application | Supported protocols | Do you need a router? | Difficulty of setup |
|---|---|---|---|
| Built-in Cast | Google Cast, DLNA | Yes (preferred) | Low |
| AirScreen | AirPlay, Miracast, Cast | No (works via AP) | Average |
| LocalCast | DLNA, SMB | Yes | Average |
| Xiaomi Share | Proprietary | No (P2P) | Low |
Another option is to use file sharing apps such as Send Files to TVThey create a direct connection between devices using technology very close to Wi-Fi DirectSimply install the app on both your phone and TV, select the file, and send it. Transfer speed is limited only by the Wi-Fi module's capabilities.
Why don't some apps see the TV?
Often, the problem lies in the AP Isolation settings on your router. If this feature is enabled, devices on the same network cannot "see" each other. Try disabling it in your router settings or using guest network mode.
Solution: The TV does not detect the device
The situation when a smartphone and a TV Xiaomi are close but don't detect each other, this happens quite often. First, check your Wi-Fi frequency. Many older TV models only work in the range 2.4 GHz, while modern smartphones can be connected to the network 5 GHzThe devices must be on the same subnet.
The second common issue is firewall or antivirus settings on the router that block ports needed for device detection. It's also worth checking whether power-saving mode is enabled on your smartphone, which could disable Wi-Fi when the screen is off.
⚠️ Attention: Operating system interfaces Android TV May be updated. Menu item locations and function names may vary depending on the firmware version and regional model of the device. If you don't find the item described, check the "About TV" section for software updates.
If software solutions don't help, try rebooting both devices. Often, simply resetting the network service cache resolves the issue of frozen discovery services. Unplug the TV for 30 seconds to completely disconnect the Wi-Fi module, then plug it back in.
Specifics of working with files via USB and local network
If your goal is not to broadcast your screen, but to watch movies or photos stored on your phone, using protocols like DLNA or SMB will be more effective than trying to find Wi-Fi Direct. TVs Xiaomi have a built-in media player that can read files from network storage.
To do this, you need to install an application on your smartphone that runs an FTP or HTTP server (for example, WiFi FTP Server). After the server starts, an IP address will appear on your phone's screen. This address should be entered into the file manager on your TV. Xiaomi or in the player VLC.
This method ensures stable transfer of large files without compression or quality loss, which is critical for viewing 4K content. Direct connections via Wi-Fi Direct emulators may be less stable in this case due to bandwidth limitations in access point mode.
This method also allows you to use your phone as a playback control. You can pause a video, change the volume, or select the next file without leaving the couch. This turns the smartphone + TV combo into a fully-fledged multimedia center.
Technical nuances and limitations of the technology
It's important to understand that even when using alternative methods, there are physical limitations. Channel capacity Wi-Fi The wireless connection is limited, and compression artifacts or audio lag may occur when transmitting high-resolution video. For fast-paced games, the wireless connection may not be responsive enough.
Distance is also an important factor. Although Wi-Fi Direct and its analogs claim a range of up to 100 meters, in an apartment with concrete walls and interference from neighboring networks, the actual range rarely exceeds 10-15 meters for stable operation. A clear line of sight between devices significantly improves the signal.
Connection security is another consideration. When using open Wi-Fi Direct (or similar) mode, data interception is theoretically possible. Therefore, it is not recommended to transmit confidential information or use open networks in public places to stream personal content to a TV.
☑️ Diagnosing communication problems
Is it possible to connect a keyboard and mouse via Wi-Fi Direct to Xiaomi TV?
Yes, but not via the standard Wi-Fi Direct interface. For connecting peripherals, it's better to use Bluetooth, either built into the remote control or the TV itself. If Bluetooth isn't available, there are special USB adapters that support 2.4 GHz that plug into the TV's USB port and function as a wireless receiver.
Why is there no sound when streaming video from my phone to TV?
This is often related to codecs. If your phone is mirroring its screen (Miracast), the audio should work. If you're using DLNA or a built-in player, make sure the audio format is supported by your TV. Try enabling surround sound in your TV settings or switching the audio output to HDMI/ARC in the system settings.
Does Wi-Fi Direct affect internet speed?
Yes, as long as the devices use the same radio module to connect to the internet and create a direct connection. When using both devices simultaneously, internet speed may decrease and ping may increase. For online gaming, it's best to disable active streaming to other devices.
How to reset all network settings on Xiaomi TV?
Go to Settings → Device Settings → Reset. Select an item Reset network settings Or a full reset if the issue is system-related. Remember, you'll have to re-enter your Wi-Fi password after this.
Does Mi TV Stick 4K support Wi-Fi 6?
Model Mi TV Stick 4K supports the standard Wi-Fi 5 (802.11ac)Full Wi-Fi 6 support is available in newer, more expensive TV models. However, Wi-Fi 5 is sufficient for streaming 4K HDR video, provided the signal is stable.
