How to connect an LG TV to the internet via a Wi-Fi router without a cable: complete instructions

Wireless TV connection LG Smart TV to the Internet via Wi-Fi router Provides access to streaming services, online cinemas, and firmware updates without the hassle of wires. However, many users encounter issues: the TV doesn't detect the network, constantly drops the connection, or requires incomprehensible settings. In this article, we'll cover all working connection methods—from basic setup to troubleshooting common errors.

It is important to understand that the process depends on the TV model (series) OLED, NanoCell, QNED or budget UK6200), firmware versions webOS and even from the router. For example, old routers with an outdated standard 802.11n Modern TVs may not support them, and some LG models require manual IP address entry. We'll cover universal methods that work on 90% of devices, as well as highlight any nuances for specific cases.

If you have already tried to connect and received an error like "Unable to connect to the network" or "IP address not received" Don't rush to reset the settings. In most cases, the problem can be resolved by changing the router settings or updating the TV's software. Let's start with preparing the equipment.

1. Preparing the TV and router before connecting

Before setting up Wi-Fi on your TV, make sure your router is ready to connect new devices. This is especially important for modern LG models with webOS 6.0+, which require a stable signal at a frequency 5 GHz to work in resolution 4K.

Here's what you need to check before starting setup:

• 📶 Wi-Fi signal: The TV must be in a strong reception area. If the router is in another room, check the signal strength on your smartphone. If it's less than 2-3 bars, you'll have to use repeater or Mesh system.
• 🔄 Router operating mode: Make sure that the router is not in the mode "Guest network only" or "Bridge"LG TV requires standard mode. Access Point (AP).
• 🔒 Wi-Fi password: Write down your current password (if you've forgotten it, look it up on the router sticker or in your provider's account). Some LG models don't support special characters in the password (e.g., #, $).
• 📡 Channel and bandwidth: In the router settings, set a fixed channel (for example, 6 or 11 For 2.4 GHz) and width 20/40 MHzAutomatic channel selection may cause connection interruptions.

If your router supports 5 GHz, but the TV LG If your router doesn't see this network, it's most likely a security issue. Many modern routers enable this by default. WPA3, which is not supported by older TV models (pre-2019). In this case, you will have to switch to WPA2-PSK or mixed mode WPA2/WPA3.

2. Step-by-step instructions: connecting LG TV to Wi-Fi

Now let's move on to the setup itself. This guide is suitable for most models. LG Smart TV on webOS (2014–2026). If you have a TV on NetCast (before 2013), the process may differ - see section for older models.

Follow this algorithm:

1. Turn on the TV and press the button Settings (gear) on the remote control.
2. Go to the section All Settings → Network → Wi-Fi Connection.
3. Select your network from the list. If it's not there, click Refresh the list or check if Wi-Fi is enabled on your router.
4. Enter your password (case sensitive!) and click Connect.
5. Wait for the message "Connected"If an error occurs, see solutions section.

If the TV asks IP address manually, this means that DHCP on the router is disabled or not working. In this case:

1. In the network settings, select Manual IP configuration.
2. Specify an IP address from the same range as the router (for example, if the router has 192.168.1.1, enter 192.168.1.100).
3. Into the fields Gateway And DNS Enter the IP address of the router (usually 192.168.1.1 or 192.168.0.1).
4. Save the settings and restart the TV.

- The TV sees the Wi-Fi network in the list

- The password was entered correctly (check the case)

- The router is not in "bridge" or "repeater" mode.

- DHCP (automatic IP distribution) is enabled on the router.

- There are no active MAC address restrictions-->

3. Configuring the router for stable operation with LG TV

Even if the TV is connected to Wi-Fi, this does not guarantee stable operation. For example, when watching 4K HDR-content on LG OLED Slowdowns may occur due to insufficient network bandwidth. To avoid problems, optimize your router settings:

If the TV stops connecting after the changes, reset the router to factory settings and try a different security standard (for example, WPA2-PSK + WPA-PSK). Also check if the function is enabled on the router. "Client Isolation" (Client Isolation) - it blocks the interaction of devices on the local network, which is why the TV may not see DLNA servers or other devices.

How to find the MAC address of an LG TV?

The MAC address is needed to bind the device to the router (if MAC filtering is enabled). To find it:

1. Go to Settings → General → About TV → TV Info.
