3. In the app on your phone (for example, Google Home) add the device to your network.
4. Use the casting feature in supported apps.

5. Troubleshooting broadcast issues

Even with proper setup, errors can still occur. Let's look at the most common ones and how to fix them.

Problem 1: TV does not appear in the list of devices

Possible causes and solutions:

• 🔌 TV and phone on different networks: Check the Wi-Fi name on both devices.
• 🔄 Screen Share is disabled: Go to Settings → Networks → Screen Share and turn it on.
• 📵 The router firewall is blocking the connection: Open the ports 55000–55004 (TCP/UDP) for local network.
• 📱 The power saving mode is enabled on the phone: Disable it in battery settings.

Problem 2: Image or sound lag

Lags in broadcasting are usually associated with:

• 📶 Weak Wi-Fi signal: Move the router closer to the TV or use a signal repeater.
• 🔄 Congested network: Disconnect other devices from Wi-Fi or switch bands 5 GHz.
• 🖥️ Low phone performance: Close background apps before broadcasting.
• 🎮 High definition broadcast: In the broadcast settings, select 720p instead of 1080p.

To test your network speed, use the app WiFi Analyzer (Android) or Network Analyzer (iOS). Optimal speed for streaming 1080p — no less 15 Mbps.

Problem 3: No sound during broadcast

If the image is broadcast but there is no sound:

• 🔊 Check if the sound on your TV is muted (Settings → Sound → Output).
• 📱 On Android In the broadcast settings, select Transmit sound (if there is such a clause).
• 🔌 For adapters Miracast make sure the sound is output through HDMI (in TV sound settings).
• 🎵 If you use Google Cast, try broadcasting the audio separately through Spotify Connect or Apple Music.

Problem 4: Broadcast interrupts or disconnects

Frequent connection breaks can be caused by:

• 🔋 Power saving on your phone: Add the broadcast application to the exceptions (for example, on Xiaomi: Settings → Battery → Battery optimization → All apps → LG TV Plus → Unlimited).
• 📡 Network interference: Switch your router to a free channel (use WiFi Analyzer for analysis).
• 🔄 Unstable TV firmware: Check for updates in Settings → General → Software Update.
• 🛠️ Protocol incompatibility: On old TVs LG try using DLNA instead of Miracast.

6. Optimize your Wi-Fi network for stable streaming

Streaming quality directly depends on your Wi-Fi network settings. The following recommendations will help minimize lag and interruptions:

1. Choosing the right band (2.4 GHz vs 5 GHz)

Televisions LG Both ranges are supported, but for broadcasting it is better to use 5 GHz:

• ✅ 5 GHz: Less interference, higher speed (up to 1 Gbps), but shorter range.
• ⚠️ 2.4 GHz: Long range, but subject to interference from other devices (microwaves, Bluetooth headsets).

How to change the range on a router:

1. Open your router's control panel (usually at 192.168.1.1 or 192.168.0.1).
2. Go to the section Wi-Fi or Wireless network.
3. Find the settings 5 GHz and enable this network (give it a unique name, for example, MyWiFi_5G).
4. Connect your TV and phone to the network 5 GHz.

2. Setting up a Wi-Fi channel

If you have a lot of neighboring networks in your home, they may be causing interference. Use an app WiFi Analyzer (Android) or NetSpot (iOS/macOS) to find a free channel.

Recommended channels:

• 📶 2.4 GHz: Channels 1, 6 or 11 (do not overlap with each other).
• 📶 5 GHz: Channels 36, 40, 44, 48 (up to 64 are allowed in Russia).

How to change the channel on a router:

192.168.1.1 → Wireless Network → 5 GHz Settings → Channel → Select Manually

3. Enabling QoS (Quality of Service)

QoS — This is a router feature that prioritizes traffic for certain devices. Configure it so that the TV LG and the phone had the highest priority:

Example for a router TP-Link:

1. Open 192.168.0.1 and go to settings.
2. Go to Additional settings → QoS.
3. Turn on QoS and select the mode By MAC address.
4. Add the MAC addresses of your TV and phone (you can find them in the network settings of each device).
5. Set maximum priority for these devices.

4. Using a Mesh system or repeater

If the TV is located far from the router, the signal may weaken. Solutions:

• 📡 Mesh system: For example, TP-Link Deco or Google Nest WiFi provide stable coverage throughout the home.
• 🔄 Repeater: Devices like Xiaomi WiFi Repeater They enhance the signal, but may increase ping.
• 🔌 Powerline adapters: The Internet is transmitted through electrical wiring (for example, TP-Link AV1000).

For TVs LG in a large apartment it is optimal to use Mesh system, as it supports roaming between access points without losing connection.

7. Comparison of broadcasting methods: which one to choose?

The choice of method depends on your needs and equipment. Below is a comparison table with the pros and cons of each option:
