LG TV Keeps Disconnecting from Wi-Fi? 8 Fixes That Work
An LG webOS TV that keeps dropping Wi-Fi almost always has a network-side problem — weak signal, an unstable 5 GHz band or a router glitch — not a broken TV. A structured restart plus a fresh connection fixes most cases.
Quick answer
Constant Wi-Fi drops on an LG TV are almost always a network-side fault. Restarting everything in the right order and refreshing the connection fixes most cases.
- 1.Unplug modem, router and TV. Plug the modem in first, wait for its lights, then the router, then the TV.
- 2.If it still drops, go to Settings → General → Network → Wi-Fi Connection, delete the saved network and reconnect — ideally on the 2.4 GHz band.
What it means
When your LG TV keeps disconnecting from Wi-Fi, it joins the network fine but loses the link afterwards — usually because the signal is borderline, the 5 GHz band is unstable at that distance, or the router needs a refresh.
LG's own troubleshooting for constant disconnects focuses entirely on the network side: restarting modem, router and TV in the right order, improving signal strength and switching bands. An actual hardware fault in the TV's Wi-Fi module is rare.
Common causes
- Weak or borderline Wi-Fi signal. The TV sits too far from the router or behind walls and furniture. LG recommends keeping the router within about 30 ft (9 m) of the TV.
- Unstable 5 GHz connection. 5 GHz is faster but has shorter range and gives up sooner through walls. LG suggests trying the 2.4 GHz band when the connection keeps dropping.
- Router or modem glitch. A router that has been running for weeks can silently corrupt its connection table; the TV is often the first device to suffer.
- Stale saved network profile on the TV. An old saved connection with outdated settings can reconnect unreliably. Forgetting the network and reconnecting clears it.
- DNS trouble. If the TV says it is connected to Wi-Fi but keeps losing internet, your provider's DNS may be the failing piece rather than the signal.
- Outdated webOS firmware. Older firmware builds can carry connectivity bugs that later updates fix.
Before you start
- Check whether other devices (phone, laptop) also drop from the same Wi-Fi. If everything drops, the problem is the router or your ISP, not the TV.
- Note when the TV disconnects: only while streaming, only after waking from standby, or at random. Each pattern points at a different fix below.
- If you can, run the TV on an Ethernet cable for a day. Rock solid on cable means the Wi-Fi path (signal, band, router) is the problem — not the TV.
Fixes, from safest to last resort
Restart modem, router and TV — in that order
No data loss- 1Unplug the modem, the router and the TV from power.
- 2Plug the modem back in first and wait until its lights are stable, then the router, and wait again for it to fully come up.
- 3Plug the TV in last, turn it on and reconnect to Wi-Fi.
This is the restart order LG recommends. Rebooting in the wrong order is why a simple restart often 'doesn't work' — the TV asks for a connection before the network is ready.
Improve the signal between router and TV
No data loss- 1Move the router closer — LG recommends keeping it within about 30 ft (9 m) of the TV.
- 2Clear obstacles: walls, metal furniture and other electronics sitting between or right next to the router and the TV weaken the signal.
- 3If moving things isn't possible, add a Wi-Fi extender or mesh point near the TV.
Turn off Quick Start+
No data loss- 1Go to Settings → General → Devices → TV Management → Quick Start+ (on older webOS versions it sits directly under Settings → General).
- 2Switch Quick Start+ off.
- 3Unplug the TV for 60 seconds, plug it back in and watch whether the drops stop.
This is a widely reported owner fix rather than part of LG's official checklist: with the instant-on mode off, many LG TVs stop losing Wi-Fi after waking from standby.
Switch the TV to the 2.4 GHz band
Re-setup needed- 1Open Settings → General → Network → Wi-Fi Connection.
- 2Connect to your router's 2.4 GHz network name instead of the 5 GHz one.
- 3If both bands share one network name, split them in your router settings (or temporarily disable 5 GHz) so the TV can only pick 2.4 GHz.
LG suggests moving to 2.4 GHz when the connection keeps dropping — it is slower on paper but reaches further and copes better with walls.
Forget the network and reconnect
Re-setup needed- 1Go to Settings → General → Network → Wi-Fi Connection.
- 2Select your saved network and delete (forget) the connection.
- 3Reconnect from scratch and re-enter the Wi-Fi password.
This clears a stale saved profile. Your apps, accounts and picture settings are untouched.
Set the DNS manually to 8.8.8.8
Re-setup needed- 1In Wi-Fi Connection, select your connected network and open its Edit / Advanced settings.
- 2Untick 'Set Automatically', leave the IP fields as they are, and enter 8.8.8.8 as the DNS server.
- 3Save and test again.
Helps with the 'connected to Wi-Fi but no internet' pattern — that one is often DNS, not signal. Google's 8.8.4.4 works as a secondary.
8.8.8.8Update the webOS firmware
Re-setup needed- 1Go to Settings → Support → Software Update.
- 2Select Check for Updates and install anything pending.
- 3Restart the TV after the update and watch whether the disconnects stop.
Factory reset (last resort)
Removes apps & settings- 1Only when every step above failed and other devices are stable on the same Wi-Fi.
- 2Go to Settings → General → System → Reset to Initial Settings (on older webOS versions: Settings → General → Reset to Initial Settings).
- 3Set the TV up again and connect to Wi-Fi before reinstalling apps, so you can judge stability with a clean system.
⚠ A factory reset erases apps, accounts and all settings. If Wi-Fi still drops afterwards, the fault is the router, the ISP — or, rarely, the TV's Wi-Fi module.
If a menu doesn't match your TV
- Menu names shift between webOS versions: on 2020-and-newer models look under Settings → All Settings → General → Network; on older sets the Network menu sits one level higher.
- If you can't find Quick Start+ under TV Management, check directly under Settings → General — its location has moved across webOS releases.
When to contact support
Contact LG support if the TV keeps dropping Wi-Fi after a firmware update and a factory reset — especially if it is also unstable on a wired Ethernet connection:
- Have the model number ready — it's on the label on the back of the TV and under Settings → Support.
- Tell them which steps you already tried, especially the router-first restart, the 2.4 GHz test and the reset.
- If the TV is stable on Ethernet but not on Wi-Fi and it's under warranty, ask about a Wi-Fi module inspection.

Frequently asked questions
Why does my LG TV disconnect from Wi-Fi while my phone stays connected?+
Phones handle weak signal and band switching better than TVs do. The TV may simply be sitting at the edge of the 5 GHz range: move the router closer or connect the TV to the 2.4 GHz band.
Will forgetting the Wi-Fi network delete my apps?+
No. Deleting the saved connection only clears network settings and the stored password. Apps, accounts and picture settings stay. Only a full factory reset removes those.
Is Ethernet better than Wi-Fi for an LG TV?+
For stability, yes. A cable removes signal problems entirely — and it's the best diagnostic too: if the TV is rock solid on Ethernet, the Wi-Fi path (signal, band, router) is what needs fixing.
Why does the TV lose Wi-Fi every time it wakes from standby?+
That specific pattern is frequently reported alongside the Quick Start+ instant-on mode. Turn Quick Start+ off, unplug the TV for a minute and test again — many owners find the wake-from-standby drops stop, though this fix isn't in LG's official checklist.
