When in the network settings have you tried to scroll to the bottom of the network list and manually add your home network?
So I have the model Un60es8000 and is completely updated. The problem started when I switched internet service from ATT to Comcast. Basically, it only recognizes the old wifi connection and doesnt let me click a new one. When I go to search for a new wifi signal, it shows the different signals but when I try to go down to click on my router, the whole menu closes and Im back to the channel I was on before I clicked the menu. I have tried the factory reset already, but it doesnt reset network settings. How do I make my tv let me click my new router or forget my old router?
