We have a Network connection issue on our newly purchased Samsung fv. We returned a Vizio tv because we couldn't get a connection to Net Flix. After working with a tech he said to return the tv. We thought we'd try a Samsung since they are a better tv. We are having the same issue! We choose our network, it says we are connected and then says we have a "Network Connection issue". We tried changing the DNS# as suggested in previous posts and have gone back to original settings but nothing seems to work. We have a cable box from Comcast. Does anyone have any suggestions that might help? Thank you!
