Modern televisions, such as the model LG LK5910PLC, are multimedia centers whose capabilities are significantly limited without internet access. The lack of a wireless connection prevents users from watching movies through online cinemas, using the smartphone screen as a remote control, or controlling voice assistants. This is why proper setup is essential. Wi-Fi connections becomes a top priority immediately after unpacking the device.
Integrating a TV into a home network is usually straightforward, but there are some nuances related to router frequency ranges and firmware versions. In this guide, we'll detail the steps for a successful connection, examine common errors, and offer troubleshooting solutions so you can enjoy high-definition content without lag.
It is worth noting that the operating system interface webOSThe software installed on this model is updated periodically. The menu's appearance may vary slightly depending on the software version, but the navigation logic remains the same. Below are the current steps to help you set up your network even without a wired connection.
Preparatory stage and equipment testing
Before you begin the software setup, you need to ensure the hardware is physically ready. Make sure your router is turned on, the indicators on its case are lit or flashing normally, and the internet connection is active. For TVs LG LK5910PLC It is critical to have a stable signal, as the built-in module can be sensitive to interference in the 2.4 GHz range.
Check if you're in a strong reception area. If your router is located in an adjacent room behind a load-bearing wall, the signal may be too weak to stream 4K video. In such cases, we recommend using Wi-Fi repeaters or considering a wired connection via LAN cable if remote setup is not possible.
⚠️ Important: Make sure your router doesn't use a hidden SSID (network name). LG TVs may not detect such networks in automatic search mode, requiring manual network name entry, which isn't always convenient using the remote control.
It's also a good idea to have your remote control ready. In some cases, if the standard remote isn't responding or isn't working properly, you may need to use the buttons on the TV itself or connect a regular USB keyboard to enter the password.
Step-by-step instructions for connecting via the settings menu
To get started, turn on your TV and wait for the startup screen to load. Take the remote and press the gear button or the SettingsA quick settings menu will appear on the screen, where you need to select the "All Settings" option, usually located in the upper right corner or at the very bottom of the list.
Once you've entered the full menu, find the "Network" section. Depending on your version, webOS, which may be located in the "General" category or a separate tab. Select "Wi-Fi Connection." The system will automatically scan for available wireless networks within range.
From the list that appears, select your home network name (SSID). If the network is password-protected, which is a security standard, a virtual keyboard will appear on the screen. Be careful when entering characters, especially if the password contains capital letters or special characters. Once entered, click "Connect."
- 📶 Make sure you select the correct network name, especially if your neighbors have similar names.
- 🔑 Check your keyboard layout before entering your password to avoid errors.
- 🔄 If the connection fails the first time, try rebooting your router.
- 📡 Make sure your TV supports your router's encryption standard (WPA2/WPA3).
After successful authorization, the message "Connected" will appear on the screen, and next to the network name, a signal strength icon will appear. Now your LG LK5910PLC has access to the global network and is ready to install applications.
☑️ Check before connection
Setting up a wired connection and alternative methods
If your wireless connection is unstable or the speed is not high enough to view heavy content, the model LG LK5910PLC Allows you to use a cable connection. This is the most reliable way to ensure stable data transmission without packet loss or latency.
To do this, you'll need a standard Ethernet cable (twisted pair) with RJ-45 connectors. One end of the cable connects to a free LAN port on your router, and the other to the corresponding port on the back or side of the TV. Typically, after physical connection, the system automatically detects the wired network and prioritizes it over Wi-Fi.
In rare cases, manual IP address configuration is required. To do this, select "Edit" or "Advanced Settings" in the "Network" menu. Here you can enter a static IP address, subnet mask, and DNS servers if your ISP requires these settings.
| Parameter | Automatic (DHCP) | Manual (Static) |
|---|---|---|
| IP address | Assigned by the router | User input |
| Subnet mask | 255.255.255.0 (usually) | Set by the provider |
| Gateway | Router IP | Router IP |
| DNS | Automatically | 8.8.8.8 (Google) and others. |
Using a cable also allows you to use your TV as a media server or stream content from a PC over a local network at the maximum speed available for that port.
Solving common connection problems
Despite the simplicity of the procedure, users may encounter errors. One of the most common issues is when the TV detects the network but fails to connect, displaying an authorization error. This is most often due to an incorrect password or changes to the router's security settings.
Another common issue is "No connection to server" or "No internet access," even though a Wi-Fi connection is established. This indicates issues with the DNS or the ISP itself. Try changing the DNS servers in your network settings to public ones, such as Google's (8.8.8.8) or Cloudflare (1.1.1.1).
⚠️ Note: The menu interface and item layout may change after updating your TV's software. If you don't find the item you're looking for, look for a similar option in the adjacent settings sections.
If your TV can't see the list of available networks at all, the Wi-Fi module may be faulty or the system settings may be corrupted. In this case, resetting the network settings to factory defaults or performing a hard reset may help, but this is a last resort.
What should I do if my TV says "Not enough memory"?
If you encounter a memory error when trying to connect or install apps, try uninstalling unused apps. Also, clear your browser cache and run the Quick Help feature in the settings menu to free up system resources.
Using LG ThinQ and controlling it from your smartphone

The Screen Share feature works most reliably when both devices are connected to the same 5 GHz network, if the router supports dual-band mode.
Software Updates and Security
An internet-connected TV can update its operating system on its own. webOSRegular updates contain not only new features but also important security patches that close vulnerabilities that could theoretically allow hackers to access your home network.
You can check for updates in "General" → "About TV" → "Check for updates." We recommend enabling "Automatic Updates" so that the TV automatically installs the latest software versions in the background when you're not using it.
Also, pay attention to app access permissions in your security settings. Not all installed apps should have access to the camera (if you have one), microphone, or file system. Control these permissions in the privacy menu.
Why won't my TV connect to 5GHz Wi-Fi?
Model LG LK5910PLC Supported frequencies may be limited depending on the region and specific board revision. If the router broadcasts a 5 GHz network with a channel higher than 48 or uses the Wi-Fi 6 (ax) standard, the older TV module may not recognize them. Try separating the network names (SSIDs) for 2.4 and 5 GHz on the router and connecting to the 2.4 GHz band.
How to reset network settings on LG?
Go to "All Settings" → "General" → "Network." Find "Reset Wi-Fi Settings" or "Delete Profile." This will clear saved passwords and IP settings, which often resolves the "connected but no internet" issue.
Is it possible to connect a TV to a hidden network?
Yes, but this requires manual configuration. In the Wi-Fi menu, select "Add hidden network" (usually at the bottom of the list). You'll need to accurately enter the network name (SSID), security type, and password. A single character error in the name will prevent you from connecting.
Why change DNS on TV?
Changing your DNS to faster servers (such as Google DNS) can speed up app menu opening, YouTube and Netflix launches, and solve the problem where apps take forever to load, even though video works in the browser.
