Modern Smart TV They've transformed their TV from a simple signal receiver into a full-fledged multimedia center, but without network access, their functionality is limited. Many users face a dilemma: how to connect Wi-Fi to an LG TV without a cable or flash drive to enjoy online content? Not having to run an Ethernet cable throughout the apartment isn't just convenient; it's often the only solution for apartments with designer renovations.
In this article, we'll cover all the nuances of wireless connections, from basic router settings to complex DNS server manipulation. You'll learn why LG TV may not see the network, how to bypass speed limits and what hidden functions are available in the engineering settings menu.
Connecting over the air requires a stable signal and proper configuration of both devices. We'll cover the steps for different operating system versions. webOS, which may differ visually, but have similar operating logic.
Preparatory stage and equipment diagnostics
Before accessing the TV menu, you need to make sure your router is working properly. Often, the problem isn't with the router. LG Smart TV, and in the router's signal distribution settings. Make sure the wireless network is active on other devices, such as a smartphone or laptop, and that the internet is stable.
It's important to check the frequency range your router uses. Older TV models may not support the standard. 5 GHz, operating exclusively in the 2.4 GHz band. If your router only broadcasts 5 GHz, the TV simply won't detect the network in the list of available networks.
⚠️ Note: If the router is installed in a metal enclosure or far from the TV, the signal may be too weak for streaming video. In such cases, even with a successful Wi-Fi connection, content will constantly buffer.
For accurate diagnostics, you can use the system's built-in tools. Go to Settings → All settings → Support → Connection diagnosticsThis tool will automatically check your network status and indicate possible connection interruptions or DNS issues.
Basic wireless setup
The connection process on modern models with a shell webOS 4.0 and above is as automated as possible. You don't need any additional adapters, as the Wi-Fi module is already built into the TV's board. To get started, press the settings button on the remote (the gear icon) and select "Network."
In the menu that opens, select "Wi-Fi connection." The TV will begin scanning the surrounding area. In the list that appears, find your network name (SSID). If you changed the router name to the default one, it may look like the device model, for example, Keenetic or TP-Link.
After selecting the network, a password entry screen will appear. Use the on-screen keyboard, which is controlled by the remote control. Be careful when entering characters, as they are case-sensitive. Once entered, tap "Connect."
☑️ Connection checklist
If the connection is successful, a signal strength icon will appear in the upper right corner of the screen. The system may prompt you to update the software once the internet is back online. This is an important step, as new patches often contain fixes. Wi-Fi module.
⚠️ Note: The menu interface may vary slightly depending on the model year. If you can't find the item you're looking for, check the official user manual for your model for the exact section names.
Troubleshooting network visibility issues
Sometimes a situation arises when the router is working, other devices see the network, and LG TV — No. This may be due to the fact that the channel the router is operating on is in the 12-14 range, which is not supported by some regional TV versions.
The solution lies in the router's settings. Log into its admin panel (usually at 192.168.0.1 or 192.168.1.1) and find the wireless network section. Change the broadcast channel to a fixed one, such as 1, 6, or 11. These channels are the most stable and supported everywhere.
Another possible cause is a hidden SSID. If the network name is hidden, the TV won't be able to find it during a regular scan. In this case, you'll need to manually add the network by selecting "Add a hidden network" and entering the exact name and security type.
| Problem | Probable cause | Solution method |
|---|---|---|
| Network not found | Frequency incompatibility | Switch your router to 2.4 GHz |
| Authorization error | Incorrect password | Double-check the keyboard layout and case |
| No connection to the server | DNS issues | Change DNS to 8.8.8.8 |
| Weak signal | Obstacles or distance | Use a repeater or PowerLine |
Why is 5 GHz better but worse?
The 5 GHz band provides higher data transfer rates, which is critical for 4K content. However, it has less penetration: walls and furniture attenuate the signal more than the 2.4 GHz band. If the router is located in a different room, it's better to use the 2.4 GHz band for stability.
Manual configuration of IP and DNS addresses
Automatically obtaining addresses (DHCP) works in most cases, but sometimes it can cause conflicts or slow performance. Manually entering settings can help stabilize the connection. To do this, select "Advanced Settings" or "Change" in the network menu.
Disable the "Automatic Configuration" option and switch to manual entry. You'll need to enter the IP address, subnet mask, gateway, and DNS servers. The IP address must be in the same subnet as the router, but not the same as other devices.
Example settings:IP: 192.168.1.155
Mask: 255.255.255.0
Gateway: 192.168.1.1
DNS 1: 8.8.8.8
DNS 2: 8.8.4.4
Using public DNS from Google (8.8.8.8) or Cloudflare (1.1.1.1) often solves the problem when Wi-Fi is connected, but apps report no network connection. This bypasses provider blocking and speeds up interface response.
Using Screen Share and Miracast
If the built-in browser or apps on your TV aren't working properly, you can stream content from your smartphone. Technology Miracast (called Screen Share on LG) allows you to mirror your screen wirelessly. It's a fully functional alternative to connecting apps directly to your TV.
To launch, press the "Input" button or find the "Screen Share" app in the list of sources. Select "Mirroring" mode. On an Android smartphone, launch "Cast" or "Smart View," and on an iPhone, launch "Screen Mirroring" (AirPlay 2 support required).
This method is advantageous because the mobile device handles all video processing, and the TV only acts as a monitor. However, image quality may vary depending on the device's workload. Wi-Fi channel and the distance between gadgets.
It's worth noting that when streaming via Miracast, your phone must be connected to the same Wi-Fi network as your TV. If your router broadcasts 2.4 GHz and 5 GHz networks with different names, both devices must be connected to the same network.
Alternative ways to distribute Internet
In situations where there's no wired internet connection and no Wi-Fi router, you can use your smartphone as a hotspot. This will allow you to connect your TV to your mobile internet. However, Traffic consumption when watching 4K video can reach 7 GB per hour, so keep an eye on your tariff plan.
Enable tethering on your phone and set a network name. Find the newly created network on your TV and connect. Keep in mind that mobile internet may have speed or ping limitations, which will affect buffering.
Another option is to use a USB Wi-Fi adapter if the TV's built-in module is faulty. However, LG only supports original adapter models (e.g., TWFM-B006D), and these are currently difficult to find. This method is considered a temporary solution.
Why does the TV say "No Internet connection" even though it has Wi-Fi?
Most often, the problem lies with your ISP's DNS servers, which aren't responding. Try setting a static DNS (8.8.8.8). Also, check the date and time on your TV—an incorrect date blocks a secure connection (HTTPS).
Can I connect my TV to 5GHz Wi-Fi?
Yes, if your TV model was released after 2014-2015 and supports the 802.11ac standard. The list of networks will show networks with the prefix "_5G" or similar. This will ensure the best speed for 4K video.
Does a hard reset of the TV reset the Wi-Fi settings?
Yes, the "Reset to Initial Settings" feature deletes all data, including saved Wi-Fi passwords, channel settings, and installed apps. After the reset, you'll need to reconnect.
How to improve Wi-Fi signal for TV?
If possible, remove any obstacles between the router and TV. If your router is dual-band, try switching to 2.4 GHz for a longer range. Updating your router's firmware may also help.
