Modern TV series LG LB650 provide access to a huge amount of online content, but they require a stable internet connection to function properly. Model 39LB650V Equipped with a built-in wireless module, it eliminates unnecessary cables and allows users to enjoy high-definition movies without interference. However, despite the well-designed webOS interface, the initial setup process sometimes raises questions among owners.
Before you begin activating Smart TV features, you need to make sure your router is working properly and is transmitting a signal within the device's range. Wireless connection This is the preferred option for this diagonal, as it eliminates the need to run a long Ethernet cable across the room. In this article, we'll detail the steps to get you online quickly.
It is worth noting that the operating system webOSThe TV installed on this model offers high response times, but requires correct network settings for apps to work. If you just purchased the TV or performed a factory reset, you'll need to re-authenticate with your home network. Let's take a look at the preparation steps.
Checking compatibility and preparing equipment
The first step before starting setup is a visual inspection and basic operating conditions check of the equipment. Make sure the TV LG 39LB650V Connected to a power source and within range of your router's signal. The distance between the access point and the receiver shouldn't be excessive, as reinforced concrete walls can significantly weaken the signal.
It is important to understand that this model supports the standards IEEE 802.11 a/b/g/n, which means it can operate in both the 2.4 GHz and 5 GHz bands (depending on the board revision, though 2.4 GHz is more commonly used for maximum compatibility). If your router broadcasts a network with a hidden name (SSID), you'll need to know the exact network name to enter it manually.
⚠️ Important: Make sure that MAC address filtering is not enabled on your router, otherwise the TV will not be able to access the network, even with the correct password.
To check the signal strength, you can use a smartphone at the location where the TV is installed. If the phone shows full reception, then Smart TV should do the trick. If the signal is weak, consider moving the router or using a repeater.
Setting up a connection via the webOS menu
Activating a wireless network on LG TVs is done through the central settings menu. To begin, turn on the TV and wait for the start screen to load. Take the remote control and press the gear button or the Settingsto bring up the quick access toolbar.
Next, you need to go to the advanced menu. To do this, select "All Settings," which is usually located in the upper-right corner of the screen or at the bottom of the list. In the window that opens, find the section Net (Network) and click on it. All internet connection-related settings will be available here.
- 📡 Select "Wi-Fi Connection" to go to the list of available networks.
- 🔍 Wait for the TV to scan the air and display a list of available access points.
- 🔑 Find the name of your home network in the list and click on it to enter the password.
After selecting a network, a virtual keyboard will appear on the screen. Be careful when entering the password, as the system is case-sensitive. Use the navigation buttons on the remote or the Magic Pointer for faster typing. After entering your password, click "Connect" and wait for confirmation of successful authorization.
☑️ Check before connection
Troubleshooting Wi-Fi Module Issues
Sometimes users encounter a situation where the TV simply does not detect wireless networks or the Wi-Fi button is inactive. In the model 39LB650V Wireless communication is handled by a dedicated external module that plugs into a USB port. If your device came with such an adapter (model AN-WF500 or similar), make sure it's securely inserted into the USB port on the back or side panel.
If the adapter is installed but the connection isn't working, try resetting your network settings. To do this, go to the menu Network → Advanced Wi-Fi Settings and find the option to edit or delete profiles. Delete saved networks and try to find them again. This often helps resolve software driver conflicts.
| Symptom | Possible cause | Solution method |
|---|---|---|
| Gray Wi-Fi icon | The module is not defined | Switch the USB port or replace the adapter |
| Searching networks... (endless) | Weak signal or interference | Bring the router closer and check the channels |
| Connection error | Incorrect password | Recheck your router's security key |
| No internet access | DNS issues | Manually enter DNS 8.8.8.8 |
In some cases, the problem lies in the router's software. Try temporarily disabling MAC address filtering or changing the encryption type to WPA2-PSK (AES), which is the most compatible standard for consumer electronics.
What to do if there is no built-in module?
Some early batches or regional versions may not have included a USB adapter. In this case, you'll need to purchase a compatible LG AN-WF500 adapter or use a wired LAN connection.
Manual configuration of IP and DNS addresses
Automatically obtaining settings (DHCP) works in most cases, but sometimes static IP addresses provide a more stable connection. If you experience frequent connection drops or slow content loading times, it might be worth manually setting up your settings. To do this, select "Advanced Wi-Fi Settings" in the network menu and uncheck "Automatic."
In the fields that open, you'll need to enter your IP address, subnet mask, gateway, and DNS servers. The gateway address is usually the same as your router's address (often 192.168.0.1 or 192.168.1.1). For DNS, we recommend using public servers from Google or Cloudflare, as they are faster and more reliable than standard ISP servers.
- 🌐 Primary DNS: enter
8.8.8.8for Google servers. - 🌐 Secondary DNS: enter
1.1.1.1for Cloudflare backup server. - 🔢 IP Address: Select an address outside the router's DHCP range to avoid conflicts.
After entering all the parameters, save the changes and run a connection test. The TV will attempt to connect to the LG update server. If the test is successful, you will see a corresponding message. This means network stack configured correctly and ready to work with applications.
⚠️ Note: When manually setting the IP address, make sure it is in the same subnet as your router, otherwise you will not be able to connect to the internet.
Updating TV software
After successfully connecting to the Internet, it is highly recommended to check for updates to your operating system. webOSManufacturers regularly release patches that improve the stability of the Wi-Fi module and fix app bugs. Older firmware versions may contain bugs that prevent proper connection.
To update, go to the menu All Settings → Advanced → About TV → Product and Service InformationHere, select "Check for updates." If the system finds a new version, it will prompt you to install it. Don't interrupt the update process or unplug the TV until the progress bar reaches 100%.
The process may take 5 to 15 minutes depending on your internet connection speed. After the updates are installed, the TV will automatically reboot. This is normal system behavior and is necessary for the new system files to be applied.
Using Wi-Fi Direct and Screen Share
Model LG 39LB650V Supports Wi-Fi Direct technology, which allows you to stream content directly from your mobile device to your TV screen without using a router. This is convenient if you want to share photos or videos from your smartphone but your home Wi-Fi is temporarily down.
To activate this feature, go to the apps menu and launch the "Screen Share" or "Smart Share" app. The device name and possibly a connection code will appear on the screen. Enable the screen sharing feature (Miracast, AllShare Cast, or similar) on your smartphone or tablet and select the TV from the list of available devices.
It's worth remembering that when using Wi-Fi Direct, the transmitted image quality may be lower than when streaming over a full network, as the communication channel is used exclusively for transmitting the video stream. Furthermore, in this mode, the TV will not have access to online services.
