⚠️ Note: Some early Smart TV models only support the standard
802.11nand don't see networks that operate exclusively in the 5 GHz band. Make sure your router is broadcasting a compatible signal.
Basic connection setup via the TV menu
The standard procedure for connecting to a wireless network takes a few minutes and is performed through the operating system interface. You need to go to the section Net or Connections in the main settings menu. Here, select the connection type "Wi-Fi" or "Wireless connection," after which the TV will scan the airwaves for available access points.
Once the scan is complete, a list of found networks will appear on the screen, along with their signal strength. Select your router's name (SSID) from the list. If the network is hidden and not visible in the general list, you will need to select "Add hidden network" and manually enter the network name and security type, which typically corresponds to the standard WPA2-PSK.
The next step will require you to enter your password for authorization. Use the on-screen keyboard controlled by the remote control or connect a USB keyboard for faster entry. When entering your password, be careful with the case, as the system distinguishes between uppercase and lowercase characters. After entering the information, click "Connect" and wait for confirmation of successful authorization.
☑️ Connection algorithm
If the connection is successful, the TV will automatically check for updates and prompt you to set the current date and time if these settings aren't synced automatically. A lack of internet access while connected to the router may indicate issues with the DNS server or router settings, which require further diagnostics.
Using Wi-Fi Direct to cast
Technology Wi-Fi Direct Allows you to create a direct connection between your TV and mobile device without a wireless router. This method is especially useful if your home network is overloaded or your router is far away, but you still need to stream photos or videos from your smartphone to a larger screen. Unlike a traditional connection, the TV itself becomes an access point or a peer-to-peer network node.
To activate this function, you need to find the section in the TV menu Connecting to a mobile device or Screen Share. Depending on the model and version WebOSThis option may have different names. Once enabled, the TV will begin broadcasting a signal, and its name will appear in the list of available devices on your smartphone or tablet.
When attempting to pair devices, a connection confirmation prompt may appear on the TV screen. This is a security measure to prevent unauthorized access to your display. After confirmation, the image streamed from the mobile device will appear on the smartphone screen, making it convenient for sharing presentations or viewing personal media content.
What is the difference between Miracast and Wi-Fi Direct?
Miracast is a video streaming protocol that often uses Wi-Fi Direct technology to create a communication channel. Wi-Fi Direct is a way to directly connect devices without a router. In other words, Miracast works over Wi-Fi Direct.
It should be remembered that when using a direct connection, the data transfer speed may be lower than through a full-fledged router that supports the standard 802.11acThis may cause control delays or reduced image quality when streaming heavy video. For a comfortable experience, ensure both devices are within direct line of sight of each other.
Troubleshooting network visibility and connectivity issues
One of the most common problems is the situation when the TV LG The Wi-Fi network simply isn't detected, even though other devices are working correctly. Often, the cause lies in incompatible channels or encryption standards. The router may be operating in a mode that the old TV module doesn't support, for example, only 802.11ax (Wi-Fi 6) without support for legacy modes.
Another possible cause could be a static IP address or an address conflict on the local network. In the network settings on your TV, try switching the IP mode from "Auto" to "Manual" and entering an address different from the one assigned by the router's DHCP server. You should also try changing the DNS servers to public ones, such as Google's (8.8.8.8), which often solves problems with access to content.
If the issue persists, perform a full reset of your TV's network settings. This will delete all saved passwords and connection configurations, returning the network module to its factory settings. After the reboot, try searching for the network again. In rare cases, changing your TV's regional settings may help, as different countries have different frequency restrictions.
⚠️ Note: The menu interface and item names may vary depending on the webOS version (3.0, 4.0, 5.0, 6.0, and later). If you don't find the item you're looking for, look for a similar option in related settings sections.
Diagnostics and software updates
The stability of your wireless module directly depends on the latest firmware. Manufacturers regularly release updates that fix connectivity bugs and improve compatibility with new network equipment. You can check for updates in the section All Settings → Support → Software Update.
