LG TV Error 137 — Network Connection Failed

What Does This Error Mean?

Error 137 means your LG TV tried to connect to the network and couldn't reach it.
Most cases are router-side — your phone is on Wi-Fi but the TV's DHCP request didn't get answered.
Restart the router, check the TV is on the right Wi-Fi network, and try again.
If 137 persists, set the DNS manually to 8.8.8.8 and the issue almost always clears.

Affected Models

LG OLED C3
LG OLED G3
LG NanoCell NANO75
LG QNED QNED80
LG webOS 6.0+ smart TV

Common Causes

Router rebooted while the TV was holding an old DHCP lease
TV connected to the wrong Wi-Fi network (5GHz vs 2.4GHz on dual-band routers)
DNS server at the router unreachable or slow to respond
Router firewall or parental controls blocking the TV
Router DHCP table full (rare on home networks)

How to Fix It

Restart the router.

Unplug the router for 30 seconds, plug it back in, wait 2 minutes for it to fully boot.
Most error 137 events trace to a stale DHCP lease — a router restart hands out fresh leases to all devices.
Try the TV after the router has been up for a couple of minutes.
Check which Wi-Fi network the TV is on.

Go to Settings > Network > Wi-Fi.
Make sure the TV is on YOUR home network, not a neighbour's or a guest network.
If your router uses different SSIDs for 2.4GHz and 5GHz, try switching to the other band — sometimes one works when the other doesn't.
Set DNS to 8.8.8.8 manually.

Settings > Network > Wi-Fi > tap your network > Advanced.
Switch DNS from Auto to Manual and enter 8.8.8.8 (Google's public DNS).
This bypasses any DNS issue at the router and resolves most stubborn error 137 cases.
Check router parental controls.

If you've recently added device controls, schedules, or 'Internet pause' features in your router app, the TV may be blocked.
Check the router admin or app for any device restrictions on the TV's MAC address.
Forget the network and reconnect.

Settings > Network > Wi-Fi > tap your network > Forget.
Then reconnect from scratch with the password.
This forces the TV to re-negotiate its IP from zero — useful if a stored network setting is corrupted.

Frequently Asked Questions

Why does error 137 happen mostly in the evening?

Evening peak is when household Wi-Fi gets busiest.
Router DNS lookups slow down, DHCP responses take longer, and the TV's network stack times out where it would have succeeded earlier.
Setting manual DNS to 8.8.8.8 bypasses the slow router DNS and usually fixes evening-only error 137.

Is error 137 the same as wifi-not-connecting?

Related but more specific.
Error 137 means the TV's network stack tried and failed at a specific stage — usually DHCP or DNS.
'Wi-Fi not connecting' covers everything from wrong password to router off.
Error 137 implies the TV got far enough to try, then gave up.
