Why Wi-Fi Direct Isn't Working on My TV: A Complete Troubleshooting Guide

On some TVs (for example, Sony Bravia) you can view the connection logs:

Settings → Network → Network Diagnostics → Connection Log

Look for errors like WFD_CONNECTION_FAILED or AUTHENTICATION_ERROR.

If Wi-Fi Direct isn't working, try:

• 📲 Google Cast (for Android TV and Chromecast)
• 🍎 AirPlay (for iPhone and new LG/Samsung)
• 🖥️ HDMI cable with adapter (most stable)

If after all the manipulations the TV still does not see the device, the problem may lie in hardware limitationFor example, in budget models TCL or Hisense The Wi-Fi module often does not support Direct due to a limited chipset.

4. Solutions for specific brands: Samsung, LG, Sony, Xiaomi

Each manufacturer implements Wi-Fi Direct differently. Let's look at the nuances for popular brands:

📺 Samsung (Tizen OS)

Problems most often arise due to:

• 🔄 Conflict with SmartThings: If the TV is connected to a Samsung account, Wi-Fi Direct may be blocked. Solution: temporarily unlink the TV from the account. Settings → General → Samsung Account.
• 📱 Incompatibilities with older Androids: Smartphones running Android 8 and below may not be able to see TV due to the outdated WFD protocol. Solution: Update your phone or use Smart View via USB cable.
• 🔧 Hidden settings: on models QLED 2021+ Wi-Fi Direct is hidden in Settings → General → Display & Sound → Screen Mirroring.

📺 LG (WebOS)

LG is phasing out Wi-Fi Direct in favor of AirPlay 2 And Google CastIf your model is newer than 2020:

• 🔍 Check your WebOS version: Settings → General → About TV. Versions 6.0+ do not support Wi-Fi Direct.
• 📱 For Android use LG TV Plus (application from Google Play).
• 🍎 For iPhone, turn on AirPlay V Settings → Connection → Apple AirPlay and HomeKit.

📺 Sony (Android TV)

On Sony Bravia Wi-Fi Direct works via Google Cast, but there are nuances:

• 🔧 Turn on Chromecast built-in V Settings → Network → Home Network Setup.
• 📱 On your Android smartphone, use Google Home to connect.
• ⚠️ On models X80J/X90J (2021) may need to be disabled IPv6 in the network settings.

📺 Xiaomi (PatchWall)

Xiaomi uses its own protocol Miracast+, which often conflicts with standard Wi-Fi Direct:

• 🔄 Restart your TV and smartphone simultaneously (hold the power button on the TV for 10 seconds).
• 📱 Turn on Developer mode on TV: Settings → About TV → Click 7 times on "MIUI TV Version", then activate Wireless display.
• 🔧 Update Mi Home to the latest version (in older versions there is a bug with connection).

5. Hardware limitations: when Wi-Fi Direct will never work

There are situations when the problem can't be resolved with software. Here are the signs that your TV does not physically support Wi-Fi Direct:

• 🔍 There is no mention of Wi-Fi Direct/Miracast in the model specifications on the official website.
• 🔧 There is no section in the service menu (accessible through engineering codes) WFD or Miracast.
• 📱 Not a single device (even with the same firmware) sees the TV in the list of available devices for connection.
• 🔄 After a factory reset, the function does not appear.

Typical models with hardware limitations:

⚠️ Attention: Some smart TVs from budget brands (Thomson, Dexp, BBK) may have Wi-Fi modules without Direct Mode support. Check this with the command adb shell dumpsys wifi (Requires root access on Android TV). If there is no line in the output p2pSupported: true, the function is not available.

6. Alternative ways to share your screen to a TV without Wi-Fi Direct

If Wi-Fi Direct fundamentally doesn't work, don't despair. Here are 5 proven alternatives:

1. Google Cast (Chromecast):

   Works on all Android TVs and most modern TVs. To connect:

   1. Make sure your TV and phone are on the same Wi-Fi network
   2. Open the video in YouTube/Netflix → Cast icon
   3. Select your TV from the list

   Cons: delay of up to 2 seconds when broadcasting games.

2. Apple AirPlay (for iPhone/iPad):

   Supported on Samsung 2018+, LG 2019+, Sony 2020+. Included in Settings → General → Apple AirPlay.

3. HDMI cable with adapter:

   The most stable method. Modern smartphones require an adapter. USB-C/Lightning → HDMI (For example, Anker 310 or Baseus).

4. DLNA/UPnP:

   To transfer photos/videos without mirroring, turn on TV DLNA in the network settings, on the phone use VLC or BubbleUPnP.

5. Third party applications:

   For Android: ApowerMirror, TeamViewer QuickSupport.
   

   For iOS: Screen Mirroring for Samsung TV (requires Apple TV or adapter).

If you need screen mirroring for games, the best option is HDMI or Steam Link (for PC gaming). Wi-Fi Direct and Miracast introduce 50–100 ms of latency, which is critical for shooters or racing games.
