How to enable Wi-Fi on an LG LK5910PLC TV: 3 proven methods + troubleshooting tips

TV LG LK5910PLC — a popular Smart TV model, but many users encounter issues connecting to a wireless network. Most often, difficulties arise not from hardware issues, but from obscure menu settings or outdated firmware. In this article, we'll cover all possible methods for enabling Wi-Fi on this model, from basic activation via the remote control to manually entering network parameters.

Peculiarity LK5910PLC - using the operating system webOS 3.5, which differs from newer versions (4.0+) in the menu layout. If you've previously set up Wi-Fi on other LG TVs, the interface may seem unfamiliar. We've taken this into account and adapted the instructions for your specific model's firmware.

Important: If your TV previously connected to the network but now the Wi-Fi won't turn on, the problem may be a reset router or an IP address conflict. A section on diagnostics for these situations is provided at the end of this article.

Method 1: Enable Wi-Fi via the main menu

The most standard method is to activate the wireless network through the TV settings. This method is suitable if you are setting up the TV for the first time. LG LK5910PLC or previously reset it to factory settings.

Instructions:

• 📺 Click the button Settings (gear) on the remote control.
• 🔍 In the menu that opens, select a section Net (Network).
• 🌐 Go to the submenu Connecting to a Wi-Fi network (Wi-Fi Connection).
• 🔄 Wait for the TV to search for available networks (usually takes 10–30 seconds).
• 🔑 Select your network from the list and enter the password using the on-screen keyboard.

If your network does not appear in the list, check:

• 📡 Is the router working (the indicators should be steady, not blinking).
• 🔌 Is the power cable connected to the router and is it plugged into the network?
• 🛡️ Is the network hidden in the router settings (the "Hide SSID" option).

Once successfully connected, an antenna icon with a check mark will appear in the upper right corner of the screen. If an exclamation point appears instead of a check mark, this means the TV has connected to the network but does not have internet access. In this case, proceed to diagnostics section.

Method 2: Quick connection via WPS button

If your router supports the technology WPS (Wi-Fi Protected Setup) allows you to connect your TV without entering a password. This method saves time but requires physical access to the router.

How does this work:

1. On the remote control LG LK5910PLC
go to Settings → Network → Wi-Fi.
2. Select an option WPS (PBC).
3. Within 2 minutes, press the WPS button on the router body (usually it is labeled or marked with an 🔄 icon).
4. Wait for the successful connection message to appear on the TV screen.

Advantages of the method:

• ⚡ Fast – takes less than a minute.
• 🔒 Security - no need to transmit the password over the air.
• 🛠️ Suitable for networks with complex passwords.

Flaws:

• 🚫 Not all routers support WPS (especially new models).
• ⏳ Connection time is limited (usually 120 seconds).
• 🔄 If there is a failure, you will have to repeat the procedure again.

If WPS does not work, check:

• 🔌 Is the WPS function enabled in the router settings (usually in the section Wi-Fi → WPS).
• 🕒 Has the connection timed out (on some routers it is 30 seconds).
• 📶 Is there any interference from other devices (microwaves, cordless phones).

3. Method: manual entry of network parameters

If automatic connection doesn't work or your network is hidden (not broadcasting its SSID), you can enter the settings manually. This method is also useful for networks with non-standard security settings (for example, enterprise authentication).

Step-by-step instructions:

1. Go to Settings → Network → Wi-Fi → Additional settings.
2. Select Manual connection (Manual Setup).
3. Enter the following parameters:
   • SSID: the exact name of your network (case sensitive!).
   • Security type: usually WPA2-PSK (check in your router settings).
   • Password: network security key.
   • IP settings: leave Auto (DHCP), if you are not using a static IP.

Save the settings and wait for the connection.

If you don't know the security type or other parameters, you can find out more:

• 🖥️ In the router's web interface (usually at 192.168.1.1 or 192.168.0.1).
• 📄 On the sticker on the bottom of the router (the factory SSID and password are indicated there).
• 📱 In your internet provider's mobile app (if available).

What security parameters are there?

The most common types are:

- WPA2-PSK (AES) — the safest and most recommended.

- WPA/WPA2-PSK - mixed mode (less safe).

- WEP - obsolete and unsafe (do not use!).

- Open network - without a password (risky).

If the connection is not established after manual entry, check:

• 🔤 Make sure you entered the correct SSID (note spaces and case sensitivity!).
• 🔑 Password accuracy (when entering, characters are displayed as dots—it’s easy to make a mistake).
• 🌍 Matching regional settings (in some cases, the TV and router must use the same Wi-Fi region).

4. Troubleshooting: Why Wi-Fi Won't Turn On

If none of these methods work, the problem may be due to hardware issues, outdated software, or a settings conflict. Let's look at some common scenarios and their solutions.

If your TV previously connected to Wi-Fi but now won't turn on the module, try resetting the network settings:

1. Go to Settings → General → Reset.
2. Select Reset network settings (Network Reset).
3. Confirm the action and try connecting again.

If resetting doesn't help, check your firmware version:

1. Go to Settings → General → About TV → TV Info.
2. Compare the software version with the latest available on LG's official website.
3. If necessary, update the firmware via USB or network (section Software update).

⚠️ Note: If your TV stops connecting to Wi-Fi after a firmware update, this may indicate an incompatibility between the software version and the hardware platform. In this case, try rolling back to the previous version or contact LG support with your model and firmware version.

5. Alternative ways to connect to the Internet

If Wi-Fi is on LG LK5910PLC If it still doesn't work, you can use alternative network connection methods. They're less convenient, but they'll still allow you to use Smart TV features.

Option 1: Connecting via Ethernet cable

• 🔄 Go to Settings → Network → Cable connection.
• 🔄 Wait for automatic configuration (DHCP).

Advantages:

• 🚀 Higher connection speed and stability.
• 🛡️ No problems with interference or weak signal.

Flaws:

• 🔌 You need to lay a cable (may be inconvenient).
• 📶 The TV is not mobile.

Option 2: Using a Powerline Adapter

If it is inconvenient to lay the cable, you can use adapters Powerline, which transmit the internet signal through electrical wiring. To do this:

1. Connect one adapter to the router via Ethernet.
2. Plug the second adapter into the outlet next to the TV and connect it to the port LAN on TV.
3. Set up the connection in the TV menu (similar to a cable connection).

Option 3: Mobile hotspot

A temporary solution is to share the Internet from your smartphone:

1. 📱 Enable tethering mode in your phone settings.
2. 🔗 Connect your TV to the created access point as if it were a regular Wi-Fi network.

Please note that this method is only suitable for short-term use (for example, updating firmware), as it uses up mobile data.

6. Updating firmware to fix Wi-Fi issues

If Wi-Fi is on LG LK5910PLC If the device won't turn on due to software errors, a firmware update may help. The manufacturer regularly releases patches to fix issues with network modules.

Update methods:
