In this article, we won't just list standard advice like "restart your TV." We'll also look at Hidden Causes of Wi-Fi Direct Failures on LG TVs, including problems with WPA3- encryption in new models, conflicts with Android 12+ and even hardware limitations of the chips Realtek RTL8723, which are installed in budget series. You'll learn how to distinguish a software bug from a hardware incompatibility and what to do if your TV doesn't even see the Wi-Fi Direct function in the menu.

Let us warn you right away: about 15% of cases are related to incorrigible limitations (for example, in models LG 2016–2017 the function only worked with branded devices LG). But 85% of problems can be solved with settings—and we'll show you which ones.

1. Basic Compatibility Check: Does your LG TV support Wi-Fi Direct?

Before you dig into the settings, make sure that your model LG Smart TV is generally equipped with a module Wi-Fi DirectDespite marketing claims, not all TVs support this feature out of the box. Here are the key points:

• 📅 Year of issue: Models LG to 2015 (series LB580V, LF630V) often had a stripped-down version of Wi-Fi without Direct. Check the sticker on the back panel to see if it lists a module. BCM43236, the function is most likely missing.
• 🏷️ TV series: In budget series (UK6100, UN6950) Wi-Fi Direct can only work with devices LG (smartphones, tablets). Universal support appeared only in the series NanoCell And OLED since 2018.
• 🔄 Firmware updates: In models 2016–2017 (For example, UJ630V) the function could be blocked in earlier versions of the software. Update to webOS 3.5+ sometimes solves the problem.

4. Software failures: firmware update and reset

About 40% of problems with Wi-Fi Direct LG TV These issues can be resolved by updating the firmware or resetting the settings. Here's how to do it correctly:

Firmware update:

• 🔄 Automatically: Go to Settings → Support → Software Update → Check for updatesIf a new version is available, install it. In 2020-2021 models (e.g. LG UN7300) Updating to webOS 6.0 fixes a bug where Wi-Fi Direct would break when transferring files larger than 1 GB.
• 💾 Manually: If automatic update does not work:
  1. Download the firmware for your model from the website LG (search for the exact model name on the sticker).
  2. Unzip the ZIP archive and copy the file .epk to a flash drive (FAT32).
  3. Insert the flash drive into the TV, go to Settings → General → Software Update → Update from USB.

Reset network settings:

1. Open Settings → All settings → General → Reset.
2. Select Reset network settings (do not confuse with a full reset!).

1. Unplug the TV.
2. Press and hold the button Nutrition on the remote control for 10-15 seconds (until the logo appears) LG).
3. In the recovery menu, select Reset to Initial Settings (use volume buttons to navigate).

⚠️ Attention: On TV LG OLED series C1/C2 A factory reset may result in loss of screen calibration. After the reset, it is recommended to run Settings → Picture → Screen Settings → Reset Picture Settings.

5. Hardware problems: when the hardware is to blame

If software solutions don't help, the problem may be hardware related. Here are typical hardware reasons why Wi-Fi Direct isn't working on LG TV:

• 📡 The Wi-Fi module is damaged: In models with modules Realtek RTL8188EU (For example, LG UK6300) The antenna connector often burns out. Symptoms: Wi-Fi is unstable even with a normal connection to the router.
• ⚡ Malnutrition: On TV LG 2018–2019 (series SK8000, SM8600) The Wi-Fi module may shut down due to power surges. Check the power supply—if it gets hot or makes a beeping noise, it needs to be replaced.
• 🔌 Problems with USB port: In models with an external Wi-Fi adapter (for example, LG 43LJ594V) The adapter may not be fully inserted or may be corroded. Try reconnecting it.

How to check hardware health:

1. Regular Wi-Fi test: Connect your TV to the router. If the connection is unstable (frequent disconnects, low speed), the problem is with the router.
2. Heating check: Turn on the TV for 30 minutes, then touch the back panel near the Wi-Fi module (usually near the HDMI ports). If it feels hot, it's a sign of overheating.
3. Diagnostics via the service menu: On the remote control, dial 1105 (For webOS 3.0–4.0) or 3305 (For webOS 5.0+), then go to Wi-Fi TestIf the test shows an error E6 — the module is faulty.

Repair cost:

• Wi-Fi module replacement: 2,500–5,000 ₽ (depending on the model).
• Power supply repair: 3,000–7,000 ₽.
• Cleaning oxidized contacts: 1,000–1,500 ₽.

⚠️ Attention: On TV LG OLED series G1/G2 The Wi-Fi module is integrated into the motherboard. Replacing it requires complete disassembly of the screen and costs 10,000–15,000 rubles. In such cases, it is cheaper to use alternative data transfer methods (e.g., Google Cast or HDMI cable).

7. Frequently asked questions and myths about Wi-Fi Direct on LG TV

Let's address common misconceptions and questions users may have:

Myth 1: "Wi-Fi Direct only works with LG devices."

This is only true for models up to 2017Starting from webOS 3.5 (2018 and newer), TVs LG support the universal Wi-Fi Direct protocol, compatible with any device (if they themselves support Direct). The exception is some budget series (UK6100), where the function is artificially limited.

Myth 2: "Wi-Fi Direct interferes with regular Wi-Fi."

That's not entirely true. Wi-Fi Direct uses the same module, but on a different channel. However, in TVs LG with single-antenna modules (Realtek RTL8188) Using Direct and regular Wi-Fi simultaneously can result in reduced speeds. Solution: Disable regular Wi-Fi while transferring files.

Myth 3: "Wi-Fi Direct consumes a lot of energy."

In fact, consumption is comparable to regular Wi-Fi (about 1–1.5 W). But in models LG OLED During active data transfer, the backlight brightness may increase slightly (this is a feature of the algorithm) Pixel Dimming).

❓ Why does Wi-Fi Direct only work one way (for example, it transmits from the TV to the phone, but not the other way)?

This is a protocol limitation in TVs. LG on webOS 4.0 and belowIn new models (with webOS 5.0) the problem is solved. The workaround is to use LG TV Plus or Google Files for file transfer.

❓ Is it possible to stream Netflix or YouTube from my phone to my TV using Wi-Fi Direct?

Technically yes, but there will be lag due to double compression (the video is first decoded on the phone, then re-encoded for transmission). For streaming, it's better to use Google Cast or Screen Share.

❓ Why did Wi-Fi Direct stop working after updating the firmware?

In some cases (for example, when updating webOS 4.5 → 5.0) Wi-Fi security settings are reset. Solution: go to Settings → Network → Wi-Fi Direct → Advanced and manually select the encryption type WPA2-PSK (instead of automatic WPA3).

How do I find the MAC address of my LG TV's Wi-Fi Direct module?

Go to Settings → General → About TV → Network InformationThe Wi-Fi Direct MAC address usually differs from the main Wi-Fi address by the last digit (e.g. A4:B1:E5:XX:XX:1 instead of A4:B1:E5:XX:XX:0).

❓ Why does Wi-Fi Direct only work at a distance of up to 2 meters?

On TV LG with modules Realtek RTL8723 (budget models) the transmitter power is artificially limited to 10 dBm (versus the standard 20 dBm). This is done to save power. There's no solution—use a router to increase the range.

8. When should I contact a service center?

Not all Wi-Fi Direct issues can be resolved independently. Contact a service center if:

• 🔧 The TV doesn't see any devices. via Wi-Fi Direct, although the function is enabled in the menu.
• 🔥 The Wi-Fi module is heating up or making a crackling noise. (sign of short circuit).
• ⚡ After resetting the settings, Wi-Fi Direct disappears from the menu. (the firmware may be damaged).
• 📶 Regular Wi-Fi works, but Direct doesn't. (an individual channel of the module may be damaged).

Average cost of diagnostics in service centers LG: 1,000–1,500 ₽. Repair costs:

• Wi-Fi module replacement: 3,000–6,000 ₽.
• Reflashing with recovery: 2,000–3,500 ₽.
• Power supply repair: 3,000–8,000 ₽.

Before visiting the service:

1. Take a photo of the sticker on the back of your TV (you need the exact model).
