WiFi Keeps Disconnecting
LG Smart TV
Severity: ModerateWhat Does This Error Mean?
LG TVs frequently dropping WiFi is usually caused by the TV's power saving mode turning off WiFi, router channel congestion, or a weak signal. Disable WiFi power saving and set a fixed WiFi channel on your router.
Affected Models
- LG OLED
- LG QNED
- LG NanoCell
- LG UHD
- All LG webOS Smart TVs
Common Causes
- Quick Start+ or WiFi power saving turning off WiFi during standby
- Router auto-switching channels causing disconnects
- Weak WiFi signal — TV too far from router
- DNS issue causing connection timeouts
- Router firmware bug
How to Fix It
-
Disable power saving: Settings > General > Quick Start+ > ON.
Quick Start keeps WiFi active during standby. Without it, the TV disconnects and reconnects every time you turn it on.
-
Set a fixed WiFi channel on your router.
Auto channel selection causes brief disconnects when the router switches. Set a fixed channel (1, 6, or 11 for 2.4GHz).
-
Change DNS to Google: Settings > Network > DNS > 8.8.8.8.
LG TVs sometimes have DNS timeout issues with ISP-provided DNS.
-
Move the router closer or use a WiFi extender.
LG TV WiFi antennas are not as strong as phones. A closer router or mesh system improves stability.
