The TV Won't Connect to the Internet
When the TV has difficulties connecting to the Internet, these steps may help resolve the problem.
The problem
Try this!
The TV cannot connect to 
your network or apps (for 
Internet compatible models 
only).
Make sure the TV has a network connection (
     
Settings
   
General
   
Network
   
Network Status
).
Contact your Internet service provider.
The wireless network 
connection failed.
Confirm your wireless modem/router is on and connected to the Internet.
The wireless network signal 
is too weak.
Position your wireless router, modem router, or access point in a central location. Avoid 
putting it in a corner.
Use a wireless repeater to get an instant boost in your wireless signal strength. Place the 
repeater halfway between your wireless router and your TV.
The most common wireless technology, 802.11g (wireless-G), operates at a frequency of 
2.4 GHz. This frequency is widely used by many cordless phones, microwave ovens, baby 
monitors, garage doors, and other wireless devices. Reduce interference by not using 
or turning off wireless devices that use the 2.4 GHz frequency. Instead, use devices that 
communicate via the 5.0 GHz frequency.
The software update over 
the Internet has failed.
Check the network connection status (
