(Appliances, cordless phones, stone walls/fireplaces, etc. decrease Wi-Fi strength.)
• Check the cable that connects the Modem to the Router (if you use a separate Modem and Router) to see
if it is in good condition. If it is not, replace the cable.

connection. (MENU > Network > Network Settings).
•Check Network Status (MENU > Network > Network Status) to see if the IP address is invalid, for example,

• If you see a valid Mac address, call your ISP and ask them to reset your network circuit to re-register the
Mac addresses of your new Modem/Router and the TV.
