Fix “LG TV Wi-Fi turns off automatically” — Wi-Fi is turned off, drops & disconnects

Technician avatar Technician
Hi! We’ll get your LG TV Wi-Fi turns off automatically issue sorted so streaming apps stay online instead of dropping out. I just need a quick picture of what’s happening on the TV.

When the problem happens, does your LG TV show a “WiFi is turned off” or “Not connected to the network” message in the top-right or in Network > Wi-Fi? Does the wireless toggle grey out so you can’t even turn Wi-Fi back on, or does it connect for a minute and then disconnect again?

Also, which LG Smart TV / webOS model do you have (approx. year), and is your router close by or in another room? Finally, do other devices on the same Wi-Fi (phones, laptops) stay connected, or do they also lose Wi-Fi when the TV drops?
Customer
It’s a few-years-old LG Smart TV, webOS I think. The main issue is the Wi-Fi keeps turning off by itself. I’ll be watching Netflix and suddenly it stops, then when I go to Settings > Network it says “WiFi is turned off”. Sometimes the Wi-Fi toggle is greyed out; other times I can switch it on but it just disconnects again after a few minutes.

My phone and laptop stay connected to the same router just fine, so it feels like only the LG TV won’t stay connected to Wi-Fi.

Got it, that helps a lot. On LG TVs there are a few common reasons why Wi-Fi turns off automatically or the Wi-Fi is turned off message keeps coming back:

• A glitch in webOS network settings or the Quick Start+ / power saving feature, which can put the Wi-Fi module to “sleep” instead of reconnecting properly.
• The TV hopping between 2.4 GHz and 5 GHz on dual-band routers, which can look like LG TV Wi-Fi keeps disconnecting when signal dips.
• Old firmware on the TV or router causing DHCP/IP conflicts, so the TV loses its address and Wi-Fi shuts off.
• In rarer cases, a loose internal Wi-Fi module or cable, but we always rule out software and network issues first.

We’ll first clean up settings that commonly cause LG TV Wi-Fi to turn off by itself, then we’ll test with your router so the connection stays stable.
Customer
That sounds about right. I did notice it happens more often after the TV has been in standby for a while. I turn it on, apps work for a few minutes, then Wi-Fi drops and I see “WiFi is turned off”. If I power-cycle the TV it sometimes comes back, sometimes not. I haven’t really touched any LG webOS network settings or Quick Start stuff, and the router is in the same room about 3–4 meters away.
Technician avatar Technician
Perfect, let’s start with a basic LG-specific reset that very often fixes LG TV Wi-Fi keeps turning off after standby.

Step A — Reset webOS power features and Wi-Fi module
1) On the LG remote, press Settings (gear) > All Settings > General.
2) Turn Quick Start+ off. If you see “SIMPLINK (HDMI-CEC)” or “AI Service” power options, disable anything that mentions fast start or automatic power saving for now.
3) Go to General > Time and make sure the time and time zone are correct. If it’s wrong, set it manually; wrong time can confuse network certificates and cause Wi-Fi to drop or refuse to reconnect.
4) Turn the TV off with the remote, then unplug it from power for 60 seconds. While it’s unplugged, press and hold the power button on the TV itself for 10–15 seconds to fully drain it.
5) Plug the TV back in, power it on, then go to Network > Wi-Fi Connection and see if you can turn Wi-Fi on and connect back to your home network.

Test a streaming app for a few minutes and let me know if the Wi-Fi still turns off automatically or if it’s more stable after this power reset.
Customer
I turned off Quick Start+, checked the time, and did the full power cycle like you said. After that, the TV connected to my Wi-Fi right away and I could stream for maybe 20–25 minutes without issues. Then suddenly YouTube stopped loading and when I checked the settings again it said “WiFi is turned off” and the toggle was greyed out for a bit. So the LG TV Wi-Fi still isn’t staying connected, just lasting longer now.
Technician avatar Technician
That tells us the Wi-Fi module still works, but something in the LG network profile or on the router side is making it drop and flip back to “WiFi is turned off”. Let’s clean both ends up a bit more.

Step B — Reset LG TV network & stabilize the Wi-Fi band
• On the TV, go to Settings > All Settings > Network and look for Network Reset or “Reset to Initial Settings” under Network. This clears old Wi-Fi profiles and can fix an LG TV that keeps disconnecting from Wi-Fi on the same router.
• After the reset and reboot, go back to Wi-Fi Connection and reconnect to your home network carefully, typing the password again. Avoid WEP; use WPA2/WPA3 if available.
• On your router, if 2.4 GHz and 5 GHz share the same name, consider giving them separate SSIDs, e.g. “Home-2G” and “Home-5G”. For many LG models, a stable 2.4 GHz signal reaches better through walls, while 5 GHz is faster but pickier.
• For now, connect the TV to the band with the stronger signal (often 2.4 GHz) and leave phones/laptops on 5 GHz to avoid congestion.
• While testing, pause large downloads and other streaming so we can see if it’s really a LG Smart TV Wi-Fi issue and not just a busy network.

Once that’s done, watch a show and see whether the Wi-Fi turns off automatically again or if it stays up longer.
Customer
I did the network reset on the TV, re-entered the password, and split my router so 2.4 GHz and 5 GHz have different names. I put the LG TV on the 2.4 GHz one with the better signal. It definitely feels more stable now — I got through a full episode on Netflix.

But after maybe an hour the LG TV lost Wi-Fi again. This time the toggle was still there, but it kept saying “Unable to connect to network” until I turned the TV off and back on. My other devices stayed online the whole time.
Technician avatar Technician
Good progress — we’ve gone from Wi-Fi dropping every few minutes to only occasionally. Now we’ll handle the “won’t reconnect” part that makes it feel like LG TV Wi-Fi turns off automatically and won’t come back.

Step C — Update firmware & stabilize IP / DNS
1) On the TV, go to Settings > All Settings > Support > Software Update (or About This TV) and choose Check for Updates. Install any update you see. LG often fixes Wi-Fi disconnecting issues in firmware patches.
2) After updating and rebooting, in the Network > Wi-Fi settings, open Advanced Wi-Fi Settings. If your router is doing something odd with DHCP, you can temporarily set a manual DNS like 8.8.8.8 or 1.1.1.1 while keeping IP on automatic — this sometimes stops “can’t connect” loops.
3) Reboot the router too: unplug it for 30 seconds and plug back in so it hands out fresh IP leases. A conflicting IP can make it seem like LG TV Wi-Fi is turned off even though the router is up.
4) Once everything is back online, connect the TV again and run a speed test within an app (YouTube, Netflix test video) to make sure the connection is steady, not just strong for a moment.

If after this the TV still periodically drops Wi-Fi but other devices are rock-solid, we’re likely down to a persistent software bug on the set or early signs of a weak Wi-Fi module.
Customer
There was a software update waiting, so I installed that and rebooted everything. I also set DNS to 8.8.8.8 like you suggested. After that, the LG TV Wi-Fi stayed connected through several hours of streaming without the “WiFi is turned off” message coming back.

I did see one small hiccup where Netflix buffered for a few seconds, but the Wi-Fi connection itself didn’t fully drop that time. Is there anything else I should change in settings so it doesn’t start auto-disconnecting again later?
Technician avatar Technician
That’s exactly what we want — now it behaves like a normal connection with occasional buffering instead of LG TV Wi-Fi turning off automatically all the time.

A few finishing touches to keep it that way:
• Under Settings > General > Power Saving, avoid aggressive power-saving modes that mention turning off network during standby. Choose a standard or off setting so the Wi-Fi module isn’t constantly put to sleep.
• If you use mobile hotspot or a second router sometimes, test the TV on that alternate network once. If it’s perfect there, we know any future drops are router-side; if problems follow the TV, it’s more likely a TV-side issue.
• Keep the TV and router in clear line-of-sight where possible; avoid tucking the router in a cabinet or behind the TV, as that can cause intermittent LG TV Wi-Fi disconnects when signal slightly dips.
• Try not to overload Wi-Fi with heavy downloads or cloud backups while streaming on the TV — that can look like the LG Smart TV keeps losing Wi-Fi, even though it’s actually network congestion.

With these tweaks, most LG sets stop showing the “WiFi is turned off” error unless there’s a genuine hardware fault.
Customer
I changed the power saving to minimum, moved the router so it’s not right behind the TV, and tried the TV on my phone hotspot as a test — it stayed connected there too. So it really does seem like the LG TV Wi-Fi turning off automatically problem is gone for now.

If it comes back in a few months, how do I know if it’s finally a bad Wi-Fi card versus just the router being weird again?
Technician avatar Technician
Great question. Here’s how to tell if future LG TV Wi-Fi keeps disconnecting issues are likely hardware:

• If the TV cannot see any Wi-Fi networks at all while your phone right next to it sees several, that points more to the internal Wi-Fi module or antenna.
• If the “WiFi is turned off” message appears every time you turn the TV on, and the Wi-Fi toggle stays greyed out even after factory reset, firmware update, and router tests, that’s another hardware red flag.
• If it drops Wi-Fi on every network you try (home router, guest network, phone hotspot) while all other devices are stable, that again leans toward a failing Wi-Fi card.

In those cases, the next step is usually to have a technician inspect the TV or to use a wired Ethernet connection or external streaming box as a workaround. But for a lot of people, the steps we did today are enough to stop LG TV Wi-Fi turning off automatically for good.
Customer
Got it. Right now everything works — the LG TV reconnects properly after standby, and I don’t see the “WiFi is turned off” message anymore. Thank you for walking me through all of this; I didn’t realize webOS power settings and firmware could affect LG TV Wi-Fi not staying connected so much.
Technician avatar Technician
You’re welcome — glad we could get your LG Smart TV to stay online again.

Summary: To fix an LG TV Wi-Fi turns off automatically problem, turn off Quick Start+, do a full power cycle, reset the LG network settings, put the TV on a stable 2.4/5 GHz band, update firmware, and clean up router/DNS settings. After that, the TV should stop showing “WiFi is turned off” and stay connected to your home network.

If the issue ever returns — Wi-Fi toggle greyed out, no networks detected, or constant drops — you can open a chat with an expert and we’ll go through TV and router checks with you in real time.
Customer
Sounds good. I’ll keep these steps handy in case the LG TV Wi-Fi acts up again. Thanks for making it all so clear and not just telling me to buy a new TV right away.

Any time! If a friend or family member says their LG TV Wi-Fi keeps disconnecting, WiFi is turned off keeps popping up, or their LG Smart TV won’t stay connected to Wi-Fi, you can share this checklist — and if you’d like someone to click through LG and router settings with you step by step, just start a chat with an expert and we’ll take it from there.

Quick answer: the accepted fix

Accepted fix when LG TV Wi-Fi turns off automatically: disable Quick Start+, power-cycle the TV, reset the LG webOS network settings, connect to a stable 2.4/5 GHz Wi-Fi band near the router, and update TV firmware so “WiFi is turned off” errors and random Wi-Fi drops stop coming back.

Why LG TV Wi-Fi turns off and disconnects (webOS, bands, interference)

Most LG TV Wi-Fi turns off automatically issues come from how the TV and router talk to each other, not from your internet speed. When webOS wakes from standby, power-saving features like Quick Start+ can leave the wireless module in a half-sleep state so you see “WiFi is turned off” or the toggle greyed out. Dual-band routers that move the TV between 2.4 GHz and 5 GHz can also make it feel like the LG Smart TV Wi-Fi keeps disconnecting even if other devices are fine.

Separating these factors helps: use consistent 2.4 GHz or 5 GHz SSIDs, keep the router close and in clear view, and make sure LG TV firmware and router firmware are current. Cleaning up old network profiles and doing a full power drain clears glitches so the TV stops randomly dropping or turning off Wi-Fi by itself.

How to check if it’s LG TV Wi-Fi, router, or internet causing the drops

To narrow down an LG TV Wi-Fi keeps disconnecting problem, test in this order:

First, see if other devices on the same Wi-Fi (phone, laptop) stay connected while the LG TV loses Wi-Fi. If everything drops, it’s likely the router or internet. If only the TV loses connection, connect it briefly to a phone hotspot or guest network. If Wi-Fi stays stable there, your main router settings or band steering are the culprits; if the TV drops Wi-Fi everywhere and regularly shows “WiFi is turned off”, you’re likely dealing with a TV firmware or Wi-Fi module issue.

LG TV Wi-Fi turns off automatically — quick troubleshooting tips

Turn off Quick Start+, reset network, pick a stable Wi-Fi band, then update firmware.

Fast path: open LG Settings > General and disable Quick Start+ → fully power-cycle the TV → run a Network / Wi-Fi reset in webOS → connect the TV to a clear 2.4 or 5 GHz Wi-Fi SSID near the router → update LG Smart TV firmware and reboot your router. In many cases this stops LG TV Wi-Fi turning off automatically and keeps streaming apps online.

FAQ

Why does my LG TV Wi-Fi keep turning off or saying “WiFi is turned off”?

A LG TV Wi-Fi turns off automatically problem usually means the TV’s wireless module or software isn’t waking up cleanly from standby, or it’s fighting with router settings. Common causes include Quick Start+ or power saving putting the Wi-Fi module to sleep, network glitches in LG webOS, dual-band routers moving the TV between 2.4 and 5 GHz, or outdated firmware on the TV or router.

How do I fix LG TV Wi-Fi that disconnects by itself?

To fix LG Smart TV Wi-Fi keeps disconnecting, turn off Quick Start+, fully power-cycle the TV, reset Network / Wi-Fi settings, and reconnect using the correct password to a stable 2.4 or 5 GHz SSID. Then update LG TV firmware, reboot your router, and if needed set a manual DNS like 8.8.8.8. These steps usually stop “WiFi is turned off” messages and automatic drops.

Do I need a new router if my LG TV Wi-Fi is not staying connected?

You don’t automatically need a new router. Many LG TV Wi-Fi not staying connected issues are fixed by changing Wi-Fi bands, splitting SSIDs, updating firmware, or rebooting the router more regularly. However, if all your devices randomly disconnect, or the router is very old and lacks modern Wi-Fi standards and security, upgrading can improve stability for your LG TV and everything else.

When is it a bad Wi-Fi module on my LG TV instead of a settings issue?

Suspect a failing LG TV Wi-Fi module if the TV cannot see any Wi-Fi networks while nearby phones see several, the Wi-Fi toggle stays greyed out even after factory reset and firmware update, or the TV drops Wi-Fi on every router and hotspot you try. In those cases, you may need a service visit or to use Ethernet or an external streaming device as a workaround.
