Your LG TV is supposed to make streaming effortless, so it is especially frustrating when it suddenly refuses to connect to WiFi. One minute you are ready to watch Netflix, YouTube, Disney Plus, or live TV apps; the next, your screen says “WiFi is turned off,” “Unable to connect to network,” or simply sits on a spinning loading icon. The good news is that most LG TV WiFi problems are caused by simple network settings, router issues, signal interference, or outdated software—and you can usually fix them without calling a technician.
TLDR: If your LG TV is not connecting to WiFi, start by restarting both the TV and router, then forget and reconnect to your wireless network. Check that your password is correct, your router is broadcasting a compatible 2.4 GHz or 5 GHz signal, and your TV software is up to date. If the issue continues, reset network settings, change DNS, move the router closer, or use an Ethernet cable as a reliable fallback.
Why Your LG TV Is Not Connecting to WiFi
LG Smart TVs use webOS to connect to your home network and run streaming apps, software updates, screen sharing, and smart home features. When WiFi stops working, the cause can be on the TV side, the router side, or somewhere in between. Before changing advanced settings, it helps to understand the most common reasons.
- Temporary software glitch: The TV or router may simply need a restart.
- Incorrect WiFi password: Even one wrong character will prevent connection.
- Weak wireless signal: Distance, walls, furniture, and appliances can reduce signal strength.
- Router compatibility issue: Some TVs struggle with certain 5 GHz channels, security modes, or band steering features.
- Outdated TV firmware: Older software can cause network bugs or app connection problems.
- DNS or IP conflict: The TV may connect to the router but fail to access the internet.
- WiFi module problem: In rare cases, the internal wireless hardware may be loose or faulty.
The best approach is to troubleshoot from easiest to most advanced. This saves time and avoids unnecessary factory resets.
1. Restart the LG TV Properly
The first fix sounds too simple, but it works surprisingly often. LG TVs do not always fully shut down when you press the power button; they may enter standby mode instead. A complete power cycle clears temporary memory and refreshes the network connection.
- Turn off the TV using the remote.
- Unplug the TV from the wall outlet.
- Wait at least 60 seconds.
- While unplugged, press and hold the TV’s physical power button for about 10 seconds, if available.
- Plug the TV back in and turn it on.
After the TV restarts, go to Settings > General > Network > WiFi Connection and try reconnecting. If the network appears and connects normally, the problem was likely a temporary webOS glitch.
2. Restart Your Router and Modem
If your LG TV can see the WiFi network but will not connect, your router may be the issue. Routers can become overloaded, especially in homes with many connected devices such as phones, laptops, tablets, cameras, consoles, and smart speakers.
To restart your network equipment:
- Unplug your modem and router from power.
- Wait 1 to 2 minutes.
- Plug in the modem first and wait until its lights stabilize.
- Plug in the router and wait for WiFi to return.
- Try connecting your LG TV again.
If all other devices are also having trouble, the issue is almost certainly with your router, modem, or internet service provider. If only the LG TV has the problem, continue with TV-specific fixes.
3. Forget the WiFi Network and Reconnect
Sometimes the saved network profile on your TV becomes corrupted. Removing the network and reconnecting creates a fresh connection.
- Press the Settings button on your LG remote.
- Go to All Settings.
- Select General, then Network.
- Choose WiFi Connection.
- Select your network and choose the option to forget or disconnect, if available.
- Scan again, select your WiFi network, and enter the password carefully.
When typing the password, remember that WiFi passwords are case-sensitive. A capital letter, space, or special symbol entered incorrectly will stop the TV from connecting. If possible, use the remote’s on-screen keyboard slowly and double-check each character before confirming.
4. Check Whether WiFi Is Turned Off on the TV
Some LG TV owners see a message that says “WiFi is turned off” even when they never turned it off manually. This can happen after a software update, a power interruption, or a hardware communication error.
Navigate to Settings > General > Network and check whether WiFi can be toggled on. If the WiFi option is missing, greyed out, or constantly switches off, try the power cycle method again. You can also disable Quick Start+, a feature that keeps parts of the TV active in standby mode and can sometimes cause network wake issues.
To disable it, go to Settings > General > Devices > TV Management or General > Quick Start+, depending on your model, then turn it off. Restart the TV afterward.
5. Move the Router Closer or Improve Signal Strength
Your LG TV may detect your WiFi network but fail to maintain a stable connection if the signal is weak. Streaming video needs more reliable bandwidth than basic web browsing, so a marginal connection can cause buffering, app errors, or complete disconnection.
WiFi signal can be weakened by:
- Thick walls, brick, concrete, or metal surfaces
- Large furniture between the TV and router
- Microwave ovens and cordless phones
- Bluetooth devices and wireless speakers
- Neighboring WiFi networks in apartments
- Routers placed inside cabinets or behind TVs
Place your router in an open, elevated position and avoid hiding it behind electronics. If the TV is far from the router, consider a mesh WiFi system, WiFi extender, or wired Ethernet connection.
6. Try 2.4 GHz Instead of 5 GHz
Many modern routers broadcast two WiFi bands: 2.4 GHz and 5 GHz. The 5 GHz band is faster but has shorter range. The 2.4 GHz band is slower but travels farther and penetrates walls more effectively. If your LG TV is far from the router, 2.4 GHz may be more stable.
If your router uses the same network name for both bands, your TV may automatically switch between them. This feature is often called Smart Connect or band steering. While convenient, it can sometimes confuse smart TVs. Log in to your router settings and, if possible, give each band a separate name, such as HomeWiFi 2G and HomeWiFi 5G. Then connect the LG TV to the one that works best.
If your TV is close to the router, 5 GHz may provide smoother 4K streaming. If it is across the house, 2.4 GHz may be the better choice.
7. Update Your LG TV Software
Outdated firmware can cause problems with WiFi, streaming apps, security certificates, and router compatibility. If your TV can connect temporarily, update it immediately.
- Press Settings on the remote.
- Open All Settings.
- Go to Support.
- Select Software Update.
- Choose Check for Updates.
- Install any available update and restart the TV.
If your TV cannot connect to WiFi at all, connect it with an Ethernet cable temporarily. Some LG models also support USB firmware updates downloaded from LG’s support website, but you must use the exact model number to avoid installing the wrong file.
8. Change DNS Settings
In some cases, your LG TV connects to WiFi but apps still say there is no internet. This may be a DNS problem. DNS is like the internet’s address book; if it fails, your TV may not be able to find streaming services even though the network connection appears active.
To set DNS manually:
- Go to Settings > General > Network.
- Select your WiFi network.
- Open Advanced WiFi Settings.
- Turn off Set Automatically, if shown.
- Enter 8.8.8.8 as the DNS server.
- Save the settings and restart the TV.
Google DNS, 8.8.8.8, is commonly used because it is fast and reliable. You can also try Cloudflare DNS, 1.1.1.1, if Google DNS does not solve the issue.
9. Check Router Security and Compatibility
Some LG TVs may struggle with certain router settings, especially on older models. If your TV sees the network but cannot connect, review these router options:
- Security mode: Use WPA2-Personal if available. Some TVs may not work well with WPA3-only mode.
- MAC filtering: Disable it or add your TV’s MAC address to the allowed list.
- Hidden SSID: Temporarily broadcast the network name to make connection easier.
- Channel selection: Try automatic channel selection or manually choose a less crowded channel.
- Guest network: Some guest networks block device communication or restrict streaming services.
If you recently replaced your router or changed your WiFi name, password, or security mode, your LG TV may need to be reconnected from scratch.
10. Use an Ethernet Cable as a Reliable Fix
If WiFi remains unstable, Ethernet is the most dependable solution. A wired connection avoids wireless interference, weak signals, and band compatibility issues. This is especially useful for 4K streaming, cloud gaming, and homes with crowded WiFi networks.
Simply plug one end of an Ethernet cable into your router and the other into the LAN port on the back of the LG TV. Then go to Settings > General > Network and select Wired Connection. In most cases, the TV will connect automatically.
11. Reset Network Settings or Factory Reset the TV
If none of the above fixes work, you can reset the TV’s network configuration. Some LG models have a specific network reset option, while others require removing saved networks manually. As a last resort, perform a factory reset.
To factory reset most LG TVs:
- Open Settings.
- Go to All Settings.
- Select General.
- Choose System or Reset to Initial Settings.
- Confirm the reset.
Important: A factory reset removes your app logins, picture settings, network settings, and preferences. Use it only after simpler steps have failed.
When It Might Be a Hardware Problem
If your LG TV never detects any WiFi networks, repeatedly says WiFi is off, or the wireless menu is missing entirely, the internal WiFi module may be faulty. On some TVs, a loose internal ribbon cable can also cause WiFi and Bluetooth problems. Signs of a hardware issue include the Magic Remote pointer not working, Bluetooth devices failing to pair, and WiFi disappearing from settings.
If your TV is under warranty, contact LG support before opening the unit. If it is out of warranty, a professional repair technician can inspect or replace the WiFi module. In the meantime, Ethernet or a streaming device connected by HDMI can keep your TV usable.
Final Thoughts
An LG TV that will not connect to WiFi can feel like a major problem, but most fixes are straightforward. Start with a full restart of the TV and router, reconnect to your network, confirm your password, and check signal strength. If the issue continues, update the software, try a different WiFi band, change DNS, or adjust router security settings.
For the most stable setup, especially if you stream in 4K, a wired Ethernet connection is hard to beat. But in many cases, a few smart network adjustments are all it takes to get your LG TV back online and ready for your next movie night.
