   Notes:

   • If your built-in wireless function is enabled, your TV should be able to find available wireless networks nearby. If your TV cannot find a Wi-Fi connection in the Network Connection list (even from other nearby sources), the TV may have a hardware issue and require repair.  Go to Product Repair. 
   • If your TV can't find your Wi-Fi network but can see wireless networks from nearby sources, your TV is functioning properly, and there may be an issue with your network. Try performing a power reset of your modem/router or contact your provider.

4. Power reset your modem/router

   A connection issue with your modem/router is often resolved after a power reset. If you have a separate modem and router, power reset both devices.

   1. Unplug the power to your modem/router and wait about 60 seconds.
   2. Reconnect your modem/router's power and ensure it's turned on.
   3. Wait until the device is finished connecting to the internet and your network.
   4. Check your network status.

   Note: If you continue to experience network/internet connection issues, check the internet connection on your other devices. If the issue exists on all devices, contact your internet service provider for additional help.
