Changed my router ten days ago from Home Hub 3 to ASUS RT N66U, and all devices successfully connected to the Internet including TV. Tonight the TV suddenly could not connect out to the Internet; nothing wrong with the wireless link, as tried Ethernet cable as well, and still no internet access. Have done factory reset of TV but to no avail. I suspect it is a setting in the router (though I cannot think why tv has worked OK for ten days then stopped). Any advice on what to check and what to change in the router? Thanks David
