Configuring network parameters and frequency ranges
The LG LK5910PLC TV supports modern wireless standards, allowing it to operate in both the 2.4 GHz and faster 5 GHz bands. Understanding the differences between them will help you optimize your data transfer speed.
The 2.4 GHz band provides greater coverage and penetrates walls better, but is often congested with signals from neighboring routers and household appliances. The 5 GHz band offers higher speed and stability, but has a shorter range.
If your router broadcasts the same network with the same name for both bands, the TV will automatically select the optimal option. However, if the networks are separate (for example, MyWiFi And MyWiFi_5G), you can manually select your preferred one.
To switch between networks, go to Settings → All settings → Network → Wi-Fi connectionClick the "Edit" or "Add" button to see the full list of available access points. Select the network with the desired frequency.
| Parameter | 2.4 GHz band | 5 GHz band |
|---|---|---|
| Transfer speed | Up to 450 Mbps | Up to 1300 Mbps and higher |
| Range | Big | Medium/Small |
| Penetration ability | High | Low |
| Workload | High | Low |
Using the 5 GHz band is especially important for watching high-definition video. 4K Ultra HD or cloud gaming. If you notice buffering when watching heavy content, try switching to this frequency if the TV is located close to the router.
What should I do if my TV can't see the 5 GHz network?
Some routers may have separate names for frequencies or a limited channel by default. Try combining the SSIDs for both frequencies in the router settings or changing the broadcast channel to 36, 40, 44, or 48, which are better supported by TVs.
Solving common connection problems
Even with proper setup, your LG TV may still refuse to connect to the network or the connection may be constantly interrupted. Most often, the problem stems from a software glitch or an IP address conflict.
