I have a Samsung series 6 smart TV and I hooked up a Belkin router so that I may enjoy watching Netflix and other things in the Smart section of my TV. I have a Samsung wireless LAN adapter and I have successfully connected to the internet through the TV. Here is the problem, whenever I try to view anything that is on the internet through the smart window it says I am not connected to the internet. I have run the checks the TV has and it always says I am connected to the internet but yet I still can't open any internet based apps. The router is only 12 ft away and all other devices pick it up fine. Anyone else have this issue or know what I can try to fix it?
