Without an internet connection, the panel's functionality is severely limited: you won't be able to use built-in apps, streaming services, or the Screen Share feature. That's why properly setting up a wireless connection is a top priority after unpacking the device.
The process of activating the communication module on this model, running on the operating system webOS, is usually straightforward, but users often encounter interface nuances. The interface may differ depending on the firmware version, but the logic remains the same. In this article, we'll walk you through each step in detail, eliminating possible errors when entering a password or selecting a security protocol.
It is worth considering that the quality of signal reception directly depends on the distance to the router and the presence of physical barriers. Model LK5400 The device is equipped with a standard Wi-Fi module, which is sensitive to interference in the 2.4 GHz band. If you plan to watch 4K content, make sure your router supports dual-band data transfer.
Preparing equipment before setup
Before accessing the TV menu, make sure the signal source is working properly. The router must be turned on, properly configured by your provider, and able to distribute internet to other devices, such as smartphones or laptops. This is a basic requirement that is often overlooked, leading to problems being addressed in TV settings where none exist.
It is also important to know your network settings. You will need the exact network name (SSID) and a password for access. If you've recently changed your router settings, make sure you remember the current information. If you're using a hidden network, you'll need to enter its name manually, which requires special attention to case sensitivity.
⚠️ Important: Make sure MAC address filtering is not enabled on your router. If the device whitelist is enabled, your TV will not be able to connect, even with the correct password. You will need to find the TV's MAC address in the "About TV" section and add it to your router settings.

What is the difference between Wi-Fi and Wi-Fi Direct?
Wi-Fi requires a router and provides internet access. Wi-Fi Direct creates a direct connection between two devices (for example, a phone and a TV) for file or image transfer, but does not provide the TV with internet access.
Screen Share is especially convenient for sharing photos, videos from your gallery, or even your smartphone's desktop. However, it's worth remembering that when actively using Wi-Fi Direct, the speed of your primary internet connection may be limited if both modules share the same frequency band.
Setting up DNS and a static IP address

In the fields that open, enter your IP address, subnet mask, gateway, and DNS servers. You can get this information from your ISP or look it up in your router settings. Content access issues are often resolved by changing your DNS to public servers, such as Google's (8.8.8.8) or Cloudflare.
| Parameter | Description | Example of meaning |
|---|---|---|
| IP address | Unique address of the TV on the network | 192.168.1.55 |
| Subnet mask | Determines the size of the network | 255.255.255.0 |
| Gateway | Your router's address | 192.168.1.1 |
| DNS server | Name server for internet access | 8.8.8.8 |
After entering all parameters, save the settings and test the connection. If the TV is successfully connected to the network, you will see a notification. Manual configuration also helps if the router is not assigning addresses automatically due to a DHCP pool overflow.
Diagnosis and solution of typical problems
Despite the simplicity of the procedure, users sometimes encounter difficulties. One common issue is that the TV sees the network but fails to connect. This could indicate an incorrect password, incompatible encryption protocols, or weak signal strength. Try rebooting the router by unplugging it for 10-15 seconds.
Another common error is the message "No internet connection" even though the Wi-Fi module is working. This means there's a connection to the router, but no access to the external network. Check your provider's balance, service status, and the integrity of the cable running from the provider to the router.
⚠️ Attention: If after resetting the network settings the TV no longer sees Wi-Fi networks (the list is empty), there may be a problem with the Wi-Fi module hardware or a system software update via a USB drive is required.
