Tv working fine except for internet. Network settings on Smart tv showed my wifi router and said: you are connected to the internet. Smart hub said: you are not connected to internet: Error_Model_Bind. I rang support, not that easy. Before I could even explain the problem the agent took all the usual info for their database. Then directed me to Menu-Support-Contact Samsung on the tv. Then asked me to read the mac address and was irritated when I didn't understand the question but eventually understood that no mac address was there. Told me the tv was faulty and gave me a tel number saying the engineer there will fix it. I rang the number and the guy said we'll pick up the tv to examine what the fault is! It's a 46 inch tv attached to the wall. Thanks Samsung.
