This is a common problem, most often caused by a software glitch or a settings conflict, rather than a malfunction of the TV itself. LG.

Before panicking and looking for a service center, it's worth running a basic diagnostic. Often, a simple hardware reboot or changing DNS server settings can solve the problem.

Ignoring the problem will result in the inability to use streaming services, YouTube, and online cinemas. Wireless connection — this is the basis of the smart TV's functionality, so restoring its functionality is necessary first and foremost.

Primary diagnostics and equipment testing

The first step should always be to check the physical condition of the devices. Make sure the router is turned on and the lights are flashing normally. Sometimes router It freezes and stops issuing IP addresses to new devices, although it still distributes Internet to those already connected.

Check if other devices, such as smartphones, tablets, or laptops, can see the network. If the Wi-Fi network isn't visible anywhere, the problem is definitely with the router. If the network is visible, but LG TV can't join it, go to software methods.

⚠️ Important! Before performing any manipulations, be sure to unplug the TV from the power outlet for 1-2 minutes. Completely disconnecting the power allows you to reset the Wi-Fi module cache, which often malfunctions when left in standby mode for long periods of time.

Resetting network and router settings

The most effective method for resolving connection conflicts is a complete reset of network settings. On TVs LG WebOS There is a quick reset feature that does not affect your installed apps but clears your network settings.

Go to the Settings menu, select "Network," and find "Wi-Fi connection." Select "Advanced Wi-Fi settings" and click "Edit." Then, remove your current network from the list of saved networks and try connecting again, entering the password.

☑️ Initial Reset Checklist

Completed: 0 / 4

If a simple reconnection doesn't help, try changing connection typeIn some cases, a static IP address conflicts with the router settings. Switch your IP settings to "Automatic (DHCP)" to allow the router to assign the correct address automatically.

It's important to ensure you don't use WPS to connect if your router is old or has a non-standard protocol implementation. Manually entering a password is often more secure than automatic pairing methods.

Why does reset help?

A complete power cycle clears errors in the Wi-Fi module's RAM. Software errors often accumulate in the clipboard, and clearing the power resets the device to factory defaults.

Changing the DNS server on an LG TV

One of the most common reasons why Smart TV "No internet connection" is a problem with the ISP's DNS server. The ISP may be blocking requests or responding slowly, which the TV interprets as a network outage.

The solution is to manually enter a public DNS address from Google or Yandex. This often "fixes" the problem instantly. Go to your network settings and select "Advanced Wi-Fi Settings."

In the menu that opens, find the "DNS Server" field. Uncheck the "Obtain automatically" box and select "Edit." Enter one of the following addresses:

  • 🌐 8.8.8.8 — Google's main server
  • 🌐 8.8.4.4 — an alternative Google server
  • 🌐 77.88.8.8 — Yandex DNS server

After entering the address, click "Connect." The TV will check the connection. If the status changes to "Connected," the issue is resolved. This method is especially useful for users whose ISPs use their own DNS with limitations.

Router settings: frequency and channels

Modern routers often operate in two bands: 2.4 GHz and 5 GHz. Older TV models LG may not support the 5 GHz frequency or the WPA3 encryption standard. If your router groups networks under a single name, the TV may attempt to connect to an unsupported band.

Try separating the networks in your router settings by giving them different names (for example, Home_2.4 and Home_5). Connect your TV to the 2.4 GHz network, as it has better penetration and compatibility with older devices.

You should also pay attention to the broadcast channel. If neighboring routers are operating on the same channel, interference will occur. Go to your router settings (usually at 192.168.0.1 or 192.168.1.1) and change the channel to 1, 6, or 11 in the Wireless settings section.

Parameter Recommended value Note
Frequency 2.4 GHz Better compatibility
Channel 1, 6, 11 Minimum interference
Encryption WPA2-PSK (AES) TV standard
Mode 802.11 b/g/n Universal mode

⚠️ Important! The interface of routers from different manufacturers (TP-Link, Asus, Keenetic) may differ. Look for sections labeled "Wireless," "Wi-Fi," or "Wireless Mode." If you're unsure, it's best to consult your router's manual.

Updating TV firmware

Outdated software is a common cause of conflicts with new router security protocols. If WebOS system It hasn't been updated for a long time, so it may simply not understand the commands of a modern router.

You can check for updates in the "General" -> "About TV" -> "Check for updates" menu. However, if the TV isn't connected to the internet, this method won't work. In this case, you'll need to update via USB.

You'll need a computer and a flash drive. Download the latest firmware version for your model from the official support website. LGPlease note the exact model indicated on the sticker on the back of the TV.

Create a folder named LG_DTV on a flash drive and place the firmware file there. Insert the drive into the TV's USB port. The system will automatically detect the update and prompt you to install it. Do not turn off the TV during the update process!

Where can I find the exact model?

The model is indicated on the sticker on the back of the case. Look for a code like 43UM7... or 55NANO... This is the code you need to enter into the search on the manufacturer's website, as firmware for different screen sizes and series is not compatible.

Alternative connection methods

If your built-in Wi-Fi module is physically damaged, don't despair. There are several ways to resolve this issue without a trip to a service center. The simplest is to use your Wi-Fi router in client or repeater mode if your primary router is far away.

However, a more reliable option is connecting via a LAN cable. If the TV and router are in the same room or a cable can be run, use an Ethernet connection. It provides more stable speeds and is unaffected by interference.

You can also use your smartphone as a modem, but this method is expensive in terms of data usage. It's best to consider purchasing an external Wi-Fi adapter if your TV model supports external dongles (although modern ones LG most often have built-in non-removable modules).

Why does the TV see the network but not connect?

Most often, this is a problem with encryption protocol mismatches. The router may use WPA3, but the TV only supports WPA2. Another possible cause is an overflowing DHCP client table on the router—the device simply doesn't have enough free IP addresses.

Is it possible to connect a phone to a TV without Wi-Fi?

Yes, using Wi-Fi Direct or Screen Share (Miracast), which create a direct connection between devices without a router. However, viewing online content from YouTube will still require internet access.

Will a factory reset help?

A full reset (Reset to Initial Settings) will delete all your accounts and settings, returning your TV to its out-of-the-box state. This is a drastic method that resolves 90% of software issues, but it requires reconfiguring all apps.

Does antivirus software on a router affect TV connection?

Yes, some parental control or antivirus features on your router may block unknown devices. Check the Blacklist in your router's security settings.
