⚠️ Attention: On some devices Xiaomi And Huawei Wi-Fi Direct may automatically turn off after 5-10 minutes of inactivity. To prevent this, enable "Always on" mode in the advanced settings.
2. Transferring files between devices: a step-by-step guide
One of the most requested features of Wi-Fi Direct is file sharing without internetThe transmission speed can reach 250 Mbps (in theory), which is 5-10 times faster than Bluetooth. Let's look at the process using smartphones and TVs as examples.
From smartphone to smartphone (Android):
- Open Gallery or File manager.
- Select files (photos, videos, documents).
- Click "Send» → select «Wi-Fi Direct».
- In the list of devices, select the target gadget (for example, Samsung Galaxy A54).
- On the receiving device, confirm receipt.
From phone to TV (for example, LG OLED C2):
- 📱 On your smartphone: in the menu
Wi-Fi DirectSelect TV. - 📺 On TV: in settings, go to
Network → Wi-Fi Direct → Receive files. - 📎 Send files using the standard "Share" menu on your phone.
Make sure Wi-Fi Direct is enabled on both devices|
Check that there is sufficient space on the receiving device|
Disable power saving mode (may disconnect connection)|
Close background apps that use Wi-Fi (such as downloaders)
-->
The transfer speed depends on:
| Factor | Impact on speed |
|---|---|
| Distance between devices | Up to 1 m – maximum speed; 5+ m – drop up to 30% |
| Wi-Fi standard (802.11ac vs 802.11n) | 802.11ac gives up to 250 Mbps, 802.11n — up to 150 Mbit/s |
| Presence of obstacles | Walls and furniture reduce speed by 40–60% |
| Channel occupancy | If there are other Wi-Fi networks operating nearby on the same channel, the speed drops. |
⚠️ Please note: Some TVs (eg. Sony Bravia 2020–2022) support receiving files only in the following formatsJPEG,MP4And
3. Screen Streaming to TV: Screen Mirroring vs. Wi-Fi Direct
Many people are confused Wi-Fi Direct And Screen Mirroring (For example, Smart View on Samsung or Miracast). The difference is that Wi-Fi Direct is connection protocol, and Screen Mirroring - screen broadcast technology, which can work over Wi-Fi Direct.
How to cast your smartphone screen to TV:
- On TV: turn on
Screen Mirroring(on LG —Wireless Display, on Sony —Miracast). - On a smartphone: in the menu
Wi-Fi DirectSelect TV. - In the notification panel of your smartphone, tap "Screencasting" (or "Smart View» on Samsung).
- Confirm the connection on TV.
Problems and solutions:
- 🔴 No sound during broadcast: Check if your TV supports Wi-Fi Direct audio streaming (on some models) Xiaomi TV sound only comes via HDMI).
- 🔴 Video lag and stuttering: Reduce the broadcast resolution in the Screen Mirroring settings (select
720pinstead of1080p). - 🔴 The TV doesn't find the smartphone.: Restart both devices and re-enable Wi-Fi Direct.
4. Multiplayer games and connecting peripherals
Wi-Fi Direct allows you to organize local gaming sessions without an internet connection. For example, in Minecraft, Asphalt 9 or Brawl Stars You can create a room for friends connected via Wi-Fi Direct. The response time (ping) will be lower than over a mobile internet connection.
How to play via Wi-Fi Direct:
- On the main device (host), create a Wi-Fi Direct access point.
- On other devices, connect to this point.
- In the game, select the "Local area network" or "Wi-Fi Direct».
- Create a room or join an existing one.
Wi-Fi Direct is also used to connect:
- 🎮 Gamepads (For example, Xbox Controller or DualSense to a PC without Bluetooth).
- 🖨️ Printers (models Canon or Epson with direct printing support).
- 📷 Cameras (For example, Sony Alpha for broadcasting the view in real time).
How to reduce lag in games over Wi-Fi Direct?
Use the 5 GHz band (if supported) - it is less crowded.
Disable background data syncing (such as cloud backups).
Reduce the game's graphics settings to minimum - this will reduce the network load.
Place the devices no more than 3 meters apart.
5. Security settings: how to protect your connection
Wi-Fi Direct uses encryption by default. WPA2, but some devices (especially older models) may operate in unsecured mode. This makes the connection vulnerable to data interception.
How to check and strengthen protection:
- 🔒 On Android: in the menu
Wi-Fi Directfind the item "SecurityPassword" If it is not there, the connection is not secure. - 🔑 On TVs Samsung (2021+ models): The Wi-Fi Direct password is generated automatically and displayed on the screen the first time you connect. Write it down!
- 🛡️ For devices without encryption: use a VPN (e.g. ProtonVPN) for transferring confidential files.
List of devices with known Wi-Fi Direct vulnerabilities (as of 2026–2026):
| Device | Problem | Solution |
|---|---|---|
| Xiaomi Mi Box S | No encryption on first connection | Update your firmware to version 2.4.5+ |
