Fix “LG TV won’t connect to Wi-Fi” — LG Smart TV no internet, Wi-Fi turned off, keeps disconnecting

Technician avatar Technician
Hi! We’ll get your LG TV not connecting to Wi-Fi fixed so apps and streaming work again instead of showing “no internet”. I just need a quick picture of your setup so we can target the right LG Smart TV Wi-Fi fixes.

Which LG TV model or webOS version do you have (rough year is fine), and are you connecting over wireless Wi-Fi or Ethernet?

When your LG TV won’t connect to Wi-Fi, what exactly do you see in Settings > Network — “Wi-Fi is turned off”, “Not connected”, “Unable to connect to the network”, or the TV finds your SSID but fails after entering the password?

Finally, are other devices (phones, laptops) working fine on the same home Wi-Fi network, or is it only the LG Smart TV with no internet connection?
Customer
It’s an LG Smart TV from a few years ago, running webOS (not sure which version). It’s on wireless, no Ethernet.

In Network settings it shows my home Wi-Fi name, I select it, enter the password, and then I get “Unable to connect to the network”. Sometimes it briefly says “Connected to Wi-Fi but not to the internet”.

My phone and laptop work fine on the same Wi-Fi, so the internet is okay. I’ve tried restarting the TV but it still won’t connect. This “LG TV won’t connect to Wi-Fi” problem only started recently.

Got it, that’s a classic LG TV Wi-Fi not working pattern: other devices online, but the TV fails after password or says “connected, no internet”. That usually means the issue is between the TV’s wireless adapter and your router, not your ISP.

First we’ll do a clean power reset, because webOS and the LG TV network adapter can get stuck after updates or long uptimes:

Step 1 — Power-cycle TV and router
1) Turn the LG TV off and unplug it from power at the wall. Leave it unplugged for at least 60 seconds so the Wi-Fi module fully powers down.
2) While the TV is unplugged, unplug your Wi-Fi router (and modem if separate) for 30–60 seconds, then plug the router back in and wait until Wi-Fi is broadcasting again (all normal lights on).
3) Plug the LG Smart TV back in and power it on, then go to Settings > Network > Wi-Fi Connection and try connecting again.

If your LG TV still won’t connect to Wi-Fi after that full reset, we’ll dig into network status, DNS and LG webOS Wi-Fi settings next.
Customer
I powered everything off like you said. After the reboot, the TV sees my Wi-Fi name, I put in the password, and it still says “Unable to connect”. When I run Network Status it shows the TV, the router, then an X between the router and the globe (internet). Other devices at home are still online with no issue.
Technician avatar Technician
That network diagram (TV → router ✔, router → internet ✖) is helpful. It means the LG TV can see the router, but something about IP/DNS or router rules is blocking real internet access.

Let’s rule out two very common LG Smart TV won’t connect to Wi-Fi causes: wrong time/date and flaky DNS.

Step 2 — Fix time/date and try manual DNS
1) On the TV go to Settings > General > Time & Date (or System on some models). Turn off “Set automatically” and manually set the correct time and date, then save.
2) Now go to Settings > Network > Wi-Fi Connection → select your network → Advanced / Edit.
3) Uncheck “Set automatically” for DNS and enter 8.8.8.8 (Google DNS) or 1.1.1.1 (Cloudflare). Save and reconnect.

If the LG TV still has no internet connection, we’ll test whether the TV is okay by using a phone hotspot:
4) Turn on a mobile hotspot on your phone with a simple name and password.
5) On the TV, in Wi-Fi settings, look for that hotspot SSID and try connecting.

Tell me what happens: does the LG TV connect to the hotspot and load apps, or does it fail there too?
Customer
I corrected the time and set DNS to 8.8.8.8. It still wouldn’t connect to my home Wi-Fi.

Then I tried my phone’s hotspot. The LG TV connected to the hotspot on the first try and YouTube actually worked there. So it seems like the TV Wi-Fi adapter is fine, but it won’t connect to my home router.
Technician avatar Technician
Perfect test — if the LG TV connects to a phone hotspot but not your regular Wi-Fi, the TV itself is okay. The problem is some combination of router settings, Wi-Fi band, or MAC/DHCP rules on your home network.

Step 3 — Adjust router so LG TV can join
• Log in to your router’s web interface or app and check that 2.4 GHz Wi-Fi is enabled. Many LG TVs are more stable on 2.4 GHz than on certain 5 GHz channels.
• If your router uses “Smart Connect” or band steering (one name for 2.4 + 5 GHz), temporarily split the bands and give the 2.4 GHz network its own name (e.g. Home-2G). Then connect your LG Smart TV to the 2.4 GHz SSID.
• Check for MAC address filtering, parental controls or access control lists. If they’re on, either disable them or add your TV’s MAC address to the allowed list.
• In DHCP / LAN settings, make sure the router is set to assign IP addresses automatically and that there are free IPs in the pool.

After saving router changes, reboot the router once more, then on the TV go to Settings > Network, choose your 2.4 GHz network and try connecting again. If the LG TV still won’t connect to Wi-Fi, we’ll reset only the TV’s network settings next.
Customer
I split the bands and connected the LG TV to the 2.4 GHz Wi-Fi. MAC filtering was off, DHCP looks normal. After the reboot, it still sometimes says “Unable to connect” or connects for a minute then drops back to “LG TV Wi-Fi disconnected”. Other devices on the same Wi-Fi stay online.
Technician avatar Technician
That “connects briefly then drops” behavior often points to corrupted LG TV network settings or an old profile for your Wi-Fi.

Step 4 — Reset LG TV network settings and reconnect
1) On the TV, go to Settings > Network and choose your Wi-Fi → Forget. If there’s a list of old networks, forget them all so we start clean.
2) Look for an option like Reset Network or Initialization of App / Network (wording varies by webOS version). Run that to reset Wi-Fi and IP settings without wiping apps.
3) Power the TV off, unplug it for 1–2 minutes, then plug it back in.
4) Now go back to Settings > Network > Wi-Fi Connection and select your 2.4 GHz home network again, carefully re-enter the password, and try to connect.

Once it shows “Connected to internet”, open an app like YouTube or Netflix to see if streaming works or if the LG TV keeps disconnecting from Wi-Fi.
Customer
I forgot all networks, reset the network settings, power-cycled the TV and reconnected to the 2.4 GHz Wi-Fi. This time it stayed connected and apps loaded, but after 5–10 minutes it dropped again with “network disconnected”. It’s better than before but still not stable. Could this be something like signal strength?
Technician avatar Technician
Yes, intermittent “LG TV Wi-Fi keeps disconnecting” is often signal-related or interference, especially if it works on a hotspot in the same room.

Step 5 — Check LG TV Wi-Fi signal and router placement
• On the TV, go to Settings > Network > Wi-Fi Connection and look at the signal bars for your network. If you see only 1–2 bars, the LG TV has a weak connection.
• If possible, move the router closer to the TV or out from inside cabinets, behind TVs, or near thick walls. Even shifting it a few feet higher and into the open can help a lot.
• Keep the router away from cordless phone bases, microwaves, and dense metal objects which can cause Wi-Fi interference.
• If the TV has an Ethernet port and it’s practical, consider running a wired Ethernet cable from the router to the TV. A wired connection completely bypasses most LG TV Wi-Fi not working issues and is ideal for 4K streaming.

After adjusting placement (or testing Ethernet if possible), test streaming for 10–15 minutes and see if the LG TV stays connected to Wi-Fi consistently.
Customer
Signal strength was only 2 bars, so I moved the router out of a cabinet and a bit closer to the TV. Now it shows 3–4 bars. I watched Netflix for about 20 minutes and it didn’t disconnect this time.

So the main “LG TV won’t stay connected to Wi-Fi” problem seems mostly fixed. Is there anything else I should do so it doesn’t start happening again?
Technician avatar Technician
Great — stronger signal plus clean network settings usually stabilise an LG Smart TV Wi-Fi connection.

To prevent this “LG TV won’t connect to Wi-Fi” issue from creeping back:

Step 6 — Update firmware and tweak LG settings
• In Settings > General > About This TV (or similar), check for a software / firmware update. Install any pending update — LG often fixes webOS network bugs in newer firmware.
• Under Settings > General, turn Quick Start / Quick Start+ off. This feature sometimes causes LG TVs to wake up with broken Wi-Fi until you hard-reboot them.
• Keep automatic time and time zone correct; wrong time can cause app and SSL/security checks to fail, making the TV look “offline”.
• Every once in a while, power the TV off and unplug it for 30–60 seconds to clear temporary glitches in the Wi-Fi module.

With those in place, your LG TV Wi-Fi not working issue should stay fixed — and if it returns, you’ve now got a repeatable checklist to stabilise it quickly.
Customer
I turned off Quick Start+, checked for updates (it installed one), and left the router in the new spot. The LG TV now connects to Wi-Fi immediately when I turn it on and has stayed online for the last hour of watching. No more “not connected” messages.
Technician avatar Technician
Excellent — that’s what we want: your LG TV connects to Wi-Fi on its own and stays online while you stream.

Quick recap: When an LG TV won’t connect to Wi-Fi, you:
• Power-cycle TV and router
• Fix time/date and DNS
• Test a phone hotspot to prove the TV’s Wi-Fi works
• Adjust router bands (2.4 / 5 GHz), DHCP and security
• Reset LG TV network settings and reconnect
• Improve signal / move router or use Ethernet
• Update firmware and disable Quick Start+ if needed

If someone else’s LG TV Wi-Fi is not working even after all that — or if the TV never sees any networks at all — it can indicate a failing LG Wi-Fi module, which might need repair. In that case, you can always open a chat with an expert and we’ll help confirm whether it’s a hardware issue or still a settings problem.
Customer
Thanks, this was really clear. My LG Smart TV Wi-Fi is stable now and I understand what to check if it acts up again.
Technician avatar Technician
Anytime! If a friend says their LG TV won’t connect to Wi-Fi, LG webOS TV shows no internet, or the LG Smart TV keeps disconnecting from Wi-Fi, you can share this checklist — and if you’d like someone to click through router and LG network settings with you in real time, just start a chat with an expert and we’ll take it from there.

Quick answer: the accepted fix

Accepted fix when an LG TV won’t connect to Wi-Fi: power-cycle TV and router, connect the TV to a strong 2.4 GHz or 5 GHz network, reset LG network settings, set manual DNS, move the router for better signal or use Ethernet, and install the latest LG webOS firmware so Wi-Fi stays stable.

Why LG TVs lose Wi-Fi — signal, bands, firmware & router settings

Most LG TV Wi-Fi not working issues come from the local network, not the ISP. The TV is just another device on your router: if the signal is weak, if the router only broadcasts certain 5 GHz channels, or if DHCP / security rules are strict, the result is an LG Smart TV that won’t connect to Wi-Fi or keeps showing “network disconnected”.

Using a cleaner 2.4 GHz or 5 GHz band with good signal, making sure MAC filtering is off, and keeping LG webOS firmware up to date solves the majority of “LG TV no internet connection” complaints. When apps suddenly stop working after a software update, a full power reset + network reset on the TV usually clears outdated network profiles that conflict with the new firmware.

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

To narrow down an LG TV won’t connect to Wi-Fi problem, start simple:

First, verify other devices (phone, laptop) can browse on the same Wi-Fi. If everything is offline, it’s likely an ISP or router outage, not the TV. If other devices are fine but the LG Smart TV has no internet, connect the TV to a phone hotspot. If it works there, your router or its settings are the culprit. If the TV also fails on the hotspot and cannot see any networks, it’s more likely a TV Wi-Fi hardware or internal software issue and may require repair.

FAQ

Why won’t my LG TV connect to Wi-Fi?

An LG TV that won’t connect to Wi-Fi usually has a local issue: weak signal, outdated network settings, strict router security, or DNS problems. Start by power-cycling TV and router, checking that other devices are online, then resetting LG network settings, connecting to a strong 2.4 GHz or 5 GHz network, and setting manual DNS if “connected, no internet” appears.

How do I fix LG Smart TV “Wi-Fi is turned off” or “Unable to connect”?

First, unplug the TV for 1–2 minutes to fully reset the LG Wi-Fi module. Then in Settings > Network, reset network settings, forget old networks, and reconnect to your Wi-Fi with the correct password. Make sure your router’s Wi-Fi is on, MAC filtering is off, and DHCP is set to automatic. If the LG TV Wi-Fi is still off or greyed out on every network, the wireless module may need service.

Should my LG TV use 2.4 GHz or 5 GHz Wi-Fi?

Many LG Smart TVs work best on a strong 2.4 GHz network if the router is far away, because 2.4 GHz travels through walls better. If the router is nearby, a clean 5 GHz channel can give faster speeds. The key is signal strength and stability: 3–4 bars and a steady connection are more important than raw speed for fixing an LG TV Wi-Fi not working issue.

When is the LG TV Wi-Fi module likely faulty?

If your LG TV cannot see any Wi-Fi networks, drops instantly from every network and hotspot, or still shows “Wi-Fi is turned off” after resets and firmware updates, the internal Wi-Fi module may be failing. At that point, using Ethernet is a good temporary workaround, and you may need a technician to inspect or replace the wireless board.
