◀ ▶EnglishIf Your TV Fails to Connect to the InternetYour TV may not be able to connect to the Internet because your ISP has permanentlyregistered the MAC address (a unique identifying number) of your PC or modem, which itthen authenticates each time you connect to the Internet as a way of preventing unauthorizedaccess. As your TV has a different MAC address, your ISP can not authenticate its MACaddress, and your TV can not connect.To resolve this problem, ask your ISP about the procedures required to connect devices otherthan a PC (such as your TV) to the Internet.If your Internet service provider requires an ID or password to connect to the Internet, yourTV may not be able to connect to the Internet. If this is the case, you must enter your ID orpassword when connecting to the Internet.The internet connection may fail because of a firewall problem. If this is the case, contact yourInternet service provider.If you cannot connect to the Internet even after you have followed the procedures of yourInternet service provider, please contact Samsung Electronics at 1-800-SAMSUNG.
