So the faster answer is to call Samsung and ask. Here's what I know. Be sure your TV has the latest firmware and that you signed into Smart Hub. And that the router's firewall is turned off for the test.
There are other settings we can change as noted in the CNET Networking Forum "Samsung Owners Start Here." But Samsung deserves all the phone calls when they flub.
I have a samsung smart tv. I am able to use apps such as twitter, fb, netflix, etc., so I am connected to my wireless network. BUT, whenever I try to open the WEB BROWSER app.... it just goes into an updating mode..... and never opens.
What do I need to do?
