  • Slow or overloaded Domain Name System (DNS) servers can lead to connectivity problems on LG smart TVs. By default, LG TVs use the DNS server provided by your router. But you can improve performance by switching to a faster public DNS server in your TV’s network settings.
  • Setting the DNS server to, Google’s public DNS address can help stabilize internet access on your LG TV. This bypasses your existing DNS server, which may be overloaded or performing poorly. Internet requests get routed through Google’s optimized DNS service instead.
  • After updating the DNS server IP address, be sure to clear the cache and data for any apps that use internet connectivity, such as streaming platforms. Also, restart the affected apps so they re-pull DNS information from the new server.
  • Troubleshooting DNS lookup failures by changing to a reliable public DNS IP like often resolve Wi-Fi disconnections and problems launching internet-dependent apps on LG smart TVs. It’s an easy workaround when your default DNS server is struggling.

Disable Quick Start+ and SIMPLINK Features

Two LG TV features that can sometimes interfere with steady Wi-Fi connectivity are Quick Start+ and SIMPLINK. Disabling them may help stabilize wireless performance:

Quick Start+

  • This feature keeps select TV components powered on while switched off for faster rebooting. However, the standby power drainage can disrupt Wi-Fi connections when the TV is idle.
  • In the General settings menu, toggle off Quick Start+. Check if this prevents connectivity drops when the TV is powered down.



  • SIMPLINK enables controlling HDMI-connected devices like soundbars using the LG TV remote. However, issues in the interaction through HDMI-CEC can manifest as Wi-Fi glitches.
  • In General settings, switch off SIMPLINK if it is enabled. See if removing this integration stabilizes wireless performance when utilizing connected equipment.

Turning off these two convenience features eliminates some potential complications that could interfere with steady Wi-Fi connectivity on your LG smart TV. Disabling Quick Start+ and SIMPLINK may help resolve wireless performance problems.
