Fix LG TV Wi-Fi Won’t Connect (2026 webOS Guide)

Your LG smart TV won’t connect to Wi-Fi, or it keeps dropping the connection mid-stream and showing “not connected.”

The good news is that this is almost always a router, settings, or webOS quirk rather than a broken television, and there is a well-known LG trick involving Quick Start+ that fixes a huge share of these cases.

This guide isolates whether the problem is your router or the TV, then walks the exact webOS settings paths in order so you stop guessing and fix it.

Start Here: Isolate The Router From The TV

Before changing anything, find out where the fault lives. Test your phone or laptop on the same network, then run the TV’s own connection test.

Test	If it works	If it fails -> means
Phone connects to same Wi-Fi	Router is fine; focus on TV	Router/ISP outage, not the TV
TV connects to phone hotspot	TV radio works; your router/band is the issue	TV-side Wi-Fi fault, keep reading
TV works on Ethernet cable	Network is fine; Wi-Fi module suspect	Main board or port problem
Wi-Fi menu is greyed out	—	Likely Quick Start+ quirk or dead Wi-Fi module

If the hotspot test connects but your home router does not, the rest of this guide is for you.

Why Won’t My LG TV Connect To Wi-Fi?

Most LG Wi-Fi failures come from a short list of causes, and knowing them tells you which fix to try first.

Wrong password or a recently changed router password.
2.4GHz vs 5GHz confusion; the TV joins the wrong band or one is hidden.
Weak signal or router too far away.
DHCP/IP conflict or a flaky DNS server.
Outdated webOS firmware or wrong date/time on the TV.
The Quick Start+ instant-on bug that keeps a stale network state alive.
Router channel congestion or a MAC address filter blocking the TV.

Fix 1: Power-Cycle The TV And Reboot The Router

A true power-cycle clears the TV’s network stack and is the single highest-value step. Half-measures (standby) do not count.

Unplug the TV from the wall for a full 60 seconds.
While unplugged, press and hold the TV’s power button for 10 seconds to drain residual power.
Plug the router back in and let it fully boot (lights solid) before the TV.
Power the TV on and retry the connection.

Rebooting the router clears DHCP leases and channel congestion, so do both in this order.

What Is The Quick Start+ Wi-Fi Bug?

Quick Start+ is LG’s instant-on feature: it keeps the TV in a low-power sleep so it boots fast. The side effect is that the Wi-Fi module never performs a clean initialization, so it can hang onto a stale, broken network state and refuse to reconnect.

Turning it off forces a full cold boot of the Wi-Fi radio. On many sets this also un-greys a greyed-out Wi-Fi menu, which is why it is the most reported single fix for this problem.

Fix 2: The LG Quick Start+ Reset Trick

This is the one to try right after a power-cycle. The menu path varies slightly by webOS year.

Older/mid webOS: Settings > All Settings > General > Additional Settings > Quick Start+ -> Off.
Newer webOS: Settings > All Settings > General > Devices > TV Management > Quick Start+ -> Off.

Set Quick Start+ to Off.
Unplug the TV for 1 to 2 minutes so the radio fully cold-boots.
Plug back in, power on, and reconnect to your network.

If Wi-Fi was greyed out, it should now be selectable.

Fix 3: Forget The Network And Re-Enter The Password

A stored profile with an old password or bad settings will fail silently every time. Clearing it forces a fresh, clean join.

Go to Settings > Network > Wi-Fi Connection.
Select your network, choose Delete or Forget.
Re-scan, select the network, and type the password carefully.

Watch case sensitivity and easily confused characters like 0/O and 1/l. Use the “show password” eye icon if available.

Fix 4: Set DNS Manually To 8.8.8.8

If the TV joins the network but has no internet, or the test fails at the DNS stage, a manual DNS often fixes it instantly.

Open Settings > Network > Wi-Fi Connection, select your network.
Choose Advanced Wi-Fi Settings (or Advanced Settings > Edit).
Uncheck Set Automatically.
In the DNS field enter 8.8.8.8 (Google) or 1.1.1.1 (Cloudflare).
Select Connect to save.

Leave IP and gateway on automatic unless you are deliberately setting a static IP.

Fix 5: Try 2.4GHz vs 5GHz And Check The Router

Band and router settings cause more “TV-only” failures than people expect. The 2.4GHz band reaches farther and through walls; 5GHz is faster but short-range.

If your bands share one name, temporarily split them so you can pick 2.4GHz for a distant TV.
Move the TV closer or relocate the router to test signal strength.
In the router admin, confirm DHCP is enabled, set the channel to Auto (or a clear one like 1/6/11 on 2.4GHz).
Check there is no MAC address filter blocking the TV.

Fix 6: Update webOS Firmware

Outdated firmware causes Wi-Fi drops that LG later patches. If Wi-Fi is too unstable to update over the air, use Ethernet or a USB stick.

Try over the network first: Settings > Support > Software Update > Check for Updates.
No connection? Plug in an Ethernet cable temporarily and update wired.
USB method: download your model’s firmware from lg.com, place it in a folder named LG_DTV on a FAT32 USB drive, insert it, and start the update from the prompt.

Let the TV finish and restart fully; do not unplug mid-update.

Fix 7: Set The Correct Date And Time

A wrong clock breaks the secure handshake your network and apps rely on, so the TV can fail to connect even with a correct password.

Go to Settings > General > Time & Date (or System > Time).
Enable Set Automatically so the TV pulls time from the network.
Confirm the time zone is correct.

If auto-time itself needs internet, set the date and time manually once to break the loop, then switch back to automatic.

Is It The Router Or The TV?

Use this reference table to read your symptoms quickly and avoid wasted steps.

Symptom	webOS setting / action	Points to
No internet after joining	`Advanced Wi-Fi Settings > DNS` = 8.8.8.8	DNS / DHCP
Drops only after sleep/wake	`General > ... > Quick Start+` -> Off	Quick Start+ bug
Drops after an update	`Support > Software Update`	Firmware
“Wrong password” loops	Forget network, re-enter	Stored profile
Works wired, never on Wi-Fi	Ethernet test	Wi-Fi module

Fix 8: Plug In Ethernet To Isolate A Failed Wi-Fi Module

This is the decisive test. Run an Ethernet cable from your router to the TV’s LAN port and run the connection test.

If Ethernet works perfectly but Wi-Fi never connects after every fix above, the internal Wi-Fi module (or its ribbon cable to the main board) is the likely culprit.
If Ethernet also fails, the problem is your network or the main board, not the radio.

Inside many LG sets the Wi-Fi board connects by a small ribbon cable that can crimp from heat cycling, which produces exactly this “wired works, wireless dead” pattern.

Fix 9: Network Reset, Then Factory Reset, And The Honest Verdict

If nothing above works, reset the network configuration, and only then the whole TV.

Try a network/connection reset if your model offers one under Network.
Full reset: Settings > Support > Reset to Initial Settings (older: General > Reset to Initial Settings).
Reconnect to Wi-Fi during the setup wizard.

If “Wi-Fi is turned off” or a greyed-out menu survives a factory reset, that confirms a hardware fault, not a settings problem. A Wi-Fi module repair on an LG TV often costs nearly as much as a new set, so weigh warranty, repair, and replacement honestly before paying for it.

The cheap workaround in 2026 is to keep the TV wired. A plug-and-play USB-to-Ethernet adapter such as this 10/100 Mbps USB-to-Ethernet adapter can give a wired connection through a USB port if your LAN port is also faulty. Compatibility spot-check: it is marketed for TCL Roku and Samsung TVs, not officially for LG, so confirm your model accepts a USB network adapter before buying, or simply use the TV’s built-in Ethernet port if it has one.
