LG smart TV — wi-fi keeps dropping
Why does my LG smart TV keeps dropping?
The short answer
Buffering on 4K, or the TV drops off Wi-Fi every night. On the WiFiXpert Compatibility Index the LG smart TV scores 68/100, and its weakest check is "Easy to fix when it goes wrong" — which is exactly where this problem comes from. Typing a Wi-Fi password with a remote is nobody's favourite job.
We publish what breaks with each router and mesh system, and the setting that fixes it.

Free fixes, in order
- Run a network cable to the TV if the router is in the same room — it beats any Wi-Fi fix.
- Turn off the TV's 'quick start' power saving, which can drop the Wi-Fi overnight.
- Move the router so it isn't directly behind the TV or a metal bracket.
Before you spend anything
- A £5 network cable or powerline adapter before any new Wi-Fi kit.
