LG TV not connecting to WiFi — real causes, home fixes and when to call for repair
Technician
Quick questions so I don’t miss anything important:
• What type of LG TV is it — LG webOS Smart TV (with apps like Netflix), older Smart TV, or a basic model with a streaming box attached?
• What exactly do you see on the TV: “Not connected”, “Wi-Fi is turned off”, Wi-Fi option greyed out, or it sees the network but shows “Unable to connect”?
• Does your Wi-Fi work fine on phones and laptops in the same room, or do they drop too?
• Have you already tried anything like restarting the TV, rebooting the router, or doing a network reset in LG settings?
Once I know the basics, I’ll give you step-by-step LG TV Wi-Fi troubleshooting that actually goes deeper than “just reboot it”, and we’ll see if this is a router issue, a software glitch or a failing Wi-Fi module.
Technician
When a LG TV says “Unable to connect to the network” even with the right password, it’s usually one of these:
• Glitched network profile on the TV: the stored Wi-Fi settings are corrupted, so the TV keeps failing until you fully forget and re-add the network.
• IP/DNS problem: the router is up, but the LG TV doesn’t get proper IP or DNS, so it looks like the LG TV is not connecting to the internet via WiFi even though signal is fine.
• Software / firmware bug: webOS version issues where LG TV keeps disconnecting from WiFi or refuses to join certain routers until updated.
• Less common: weak Wi-Fi signal right at the TV, or an early sign of a failing Wi-Fi module inside the TV.
We’ll start with simple things in the LG menu (forgetting the network, DNS tweak, date/time), then do a router side check, and only at the very end talk about hardware.
Technician
Step 1 — Forget and re-add your Wi-Fi on the LG TV
• On the TV go to Settings ▸ All Settings ▸ Network ▸ Wi-Fi Connection (wording may vary slightly).
• Highlight your home Wi-Fi name (SSID), open options and choose Forget or “Delete”.
• Turn the TV off with the remote, wait 30 seconds, then turn it back on.
• Go back to Wi-Fi Connection, select your network again and carefully re-enter the password (case-sensitive).
Step 2 — Set DNS manually on the LG TV
• In the same Wi-Fi Connection screen, go to Advanced settings ▸ Edit for your network.
• Uncheck “Set automatically” for DNS if you see that option.
• Set DNS to 8.8.8.8 or 1.1.1.1 (public DNS).
• Save and test the connection again.
Step 3 — Check Date & Time
• Go to Settings ▸ General ▸ Time & Date and make sure the TV has the correct region and time.
• If “Set automatically” is on but the time looks wrong, temporarily turn it off and set the time manually.
Try those and tell me if the LG TV now connects, still fails, or shows a specific Wi-Fi error code.
Technician
Step 4 — Test with a phone hotspot
• Turn on the mobile hotspot on your phone and give it a simple name and password (letters and numbers only).
• On the LG TV go to Wi-Fi Connection and look for that hotspot SSID in the list.
• Try connecting using the hotspot password.
Watch what happens:
• If the LG TV connects to the hotspot, but not to your home Wi-Fi, the TV’s Wi-Fi radio is fine — the issue is router settings (security mode, band, MAC filter, etc.).
• If the LG TV won’t connect to any Wi-Fi, including hotspot, we’re likely dealing with a deeper software bug or a failing Wi-Fi module.
Let me know which way it goes — that decides if we focus on router tweaks or TV-side resets.
Technician
The most common router-side things that make an LG TV not connect to WiFi are:
• Very long or exotic Wi-Fi passwords, or special characters the TV chokes on.
• Using WPA3-only or unusual security modes instead of mixed WPA2/WPA3 or plain WPA2-PSK.
• 5 GHz band only, while some older LG models prefer 2.4 GHz, or the SSID is hidden.
Step 5 — Simplify the Wi-Fi network (temporarily)
On your router’s Wi-Fi settings page:
• Make sure the main network uses WPA2-PSK (AES) or WPA2/WPA3 mixed, not WPA3-only or WEP.
• Set a simple test password (letters + numbers, no spaces or special characters).
• If the router has separate 2.4 GHz and 5 GHz SSIDs, enable both and keep names simple (like “Home24” and “Home5G”).
• Make sure the network is not hidden and that MAC address filtering is off or your TV is allowed.
After applying those changes, reboot the router once, wait 1–2 minutes, then try connecting the LG TV again to the 2.4 GHz first. Tell me if it finally joins or still says “unable to connect”.
Technician
On LG webOS, random drops are often tied to power-saving, Quick Start, or older firmware.
Step 6 — Tweak LG TV power and Wi-Fi settings
• Go to Settings ▸ General and if you see Quick Start+ or similar, try turning it Off for now.
• In Network settings, make sure Wi-Fi is On and not showing “Wi-Fi is turned off” (if that appears, toggle it off/on once).
• If your TV has an “Energy saving” or “Power saving” mode, set it to low or turn it off while testing.
Step 7 — Update firmware when possible
• With Wi-Fi working, go to Settings ▸ Support ▸ Software Update (or “Update” in some menus).
• Enable automatic updates and run a manual “Check for updates”.
• If an update is available, install it, let the TV restart, then connect back to Wi-Fi and test for a while.
This combination often stabilizes an LG Smart TV that keeps dropping WiFi. Let me know if the drops stop or if it still disconnects after that.
Technician
For future reference (or if it starts again), there are two more patterns to watch for:
• If the TV suddenly says “Wi-Fi is turned off” and the Wi-Fi option is greyed out so you can’t toggle it on, that’s often a sign of a Wi-Fi module issue or a rare software glitch that sometimes needs a deeper reset.
• If the TV only disconnects when other devices are heavy streaming or when the microwave is on, that points more toward 2.4 GHz interference and moving either the router or TV slightly, or trying the 5 GHz network if your model supports it.
Right now though, we’ve essentially taken you through the standard LG playbook: clean Wi-Fi profile, router security fix, hotspot test, power/Quick Start adjustments, and firmware update.
Technician
To keep your LG TV from losing Wi-Fi again:
• Avoid super-complex Wi-Fi passwords or WEP/WPA3-only modes that older clients struggle with.
• If you change router, SSID or password in future, Forget the old network on the LG TV before reconnecting so it doesn’t reuse a corrupt profile.
• Keep webOS firmware reasonably up to date, especially if apps stop loading or the TV starts saying “Check your network connection” a lot.
• Consider using 5 GHz if your model supports it and the router is close — it’s usually more stable for HD/4K streaming than crowded 2.4 GHz.
And if one day the Wi-Fi option disappears, stays greyed out, or the LG TV refuses to connect to any Wi-Fi including a hotspot, that’s when it’s worth checking warranty or asking an expert whether a Wi-Fi module replacement is worth it for your specific model.
Technician
Quick answer: the accepted fix
Accepted fix when an LG TV won’t connect to WiFi: on the TV, forget your home network, reboot the TV and reconnect using a simple password, then set DNS manually (for example 8.8.8.8). If it still fails, test a phone hotspot. If the TV connects to the hotspot but not your router, switch the router to WPA2/WPA2-WPA3, avoid special characters in the Wi-Fi password, enable 2.4 GHz and try again. Update webOS firmware and disable Quick Start+. If the TV cannot connect to any Wi-Fi and shows “Wi-Fi is turned off” or a greyed-out option, the Wi-Fi hardware may need professional repair.
Why LG TVs won’t stay connected to WiFi: router, software and hardware causes
Most LG TV not connecting to WiFi cases are not random — they usually trace back to how the router and TV are configured. If your LG Smart TV says “Not Connected” or “Unable to join the network” while phones work fine, it is often a mismatch between the TV and router security mode, a corrupted Wi-Fi profile, or DNS/IP problems rather than a dead internet line. When an LG TV keeps disconnecting from WiFi, features like Quick Start+, aggressive power-saving and outdated firmware play a big role, as does interference on crowded 2.4 GHz channels. Only when your LG TV Wi-Fi is greyed out, stuck on “Wi-Fi is turned off”, or refuses to see any networks at all, do we start suspecting a failing Wi-Fi module, antenna or mainboard instead of pure configuration issues.
How to test your LG TV WiFi safely at home
To tell whether you have a router problem, a software glitch or a bad Wi-Fi module, test your LG TV internet connection step by step. Start by forgetting the home network and reconnecting with a simple password and manual DNS on the TV, then use a phone hotspot as a clean test network. If the TV connects to the hotspot but not the router, focus on router security, band, and channel settings; if it cannot connect to any network, even with hotspots, a deeper reset or hardware check is needed. Always check that other devices are online, update webOS firmware, and try toggling features like Quick Start+ before deciding that the LG TV Wi-Fi hardware is faulty. This systematic approach avoids unnecessary factory resets and helps you decide whether DIY tweaks, router changes or a service visit make the most sense.
LG TV not connecting to WiFi — quick troubleshooting tips
In most homes, a “dead” LG TV Wi-Fi connection is really a router or settings issue — not always a broken TV.
Quick path: forget and re-add your Wi-Fi network on the LG TV → set DNS manually and correct time zone → test with a mobile hotspot → adjust router security to WPA2 and try a simple 2.4 GHz network → update webOS and turn off Quick Start+ while testing. Only then decide if the LG TV Wi-Fi not working is a sign of a bad Wi-Fi module that needs repair. That sequence fixes the majority of “LG TV won’t connect to WiFi” and “LG TV Wi-Fi turned off” complaints without replacing the TV.

FAQ
Why is my LG TV not connecting to WiFi at all?
If your LG TV won’t connect to WiFi but other devices are online, start by forgetting your home network on the TV, rebooting it, and reconnecting with a simple password. Then set DNS manually (for example 8.8.8.8) and make sure the TV’s date and time are correct. If it still fails, test a phone hotspot; if the TV connects to that, your router’s security mode or password is the likely cause. If the TV cannot connect to any Wi-Fi network and the Wi-Fi option is greyed out or stuck on “Wi-Fi is turned off”, there may be a problem with the TV’s Wi-Fi hardware.
How do I fix an LG Smart TV that keeps disconnecting from WiFi?
For an LG Smart TV that keeps disconnecting from WiFi, update webOS firmware first, then turn off Quick Start+ and aggressive energy-saving features, which can put the Wi-Fi module to sleep. Make sure the router is close enough or try the 5 GHz band for better stability. If your router supports it, use WPA2-PSK security and avoid overly crowded channels. When drops happen only on the TV and not other devices, simplifying the Wi-Fi network and adjusting TV power settings usually stabilizes the connection.
What does “WiFi is turned off” or greyed out mean on my LG TV?
When an LG TV shows “Wi-Fi is turned off” and the Wi-Fi toggle is greyed out, it may be a temporary software glitch or an early sign of a failing Wi-Fi module. Try unplugging the TV from power for a full minute, then plug it back in and check Network settings again. If Wi-Fi remains unavailable, a deeper factory reset or firmware update via USB may help, but persistent greyed-out Wi-Fi after resets usually means the TV needs professional diagnosis or Wi-Fi module repair.
When should I contact support or replace my LG TV for WiFi issues?
If you have confirmed that your router and internet are stable, simplified the Wi-Fi password and security mode, tested a phone hotspot, updated firmware and adjusted TV settings, and your LG TV still won’t connect to WiFi or loses Wi-Fi completely, it is time to consider support. In particular, a TV that cannot see any networks, has the Wi-Fi option permanently greyed out, or only works on Ethernet is often showing Wi-Fi hardware failure. At that point, checking warranty options, asking about Wi-Fi module replacement, or comparing repair costs to replacement is the sensible next step.
