NSX-40GT1 TV does not detect all wifi signals. My mac is detecting a dozen networks in the same area. but the TV can only see one (unfortunately not mine). It keeps 'scanning...' but not finding anything. The one network it can see is a surewest network. It can't see any of the dozen Xfinity networks, and at my last place it couldn't see any networks. This is the second time this has happened. I moved house recently and at the last place I had this problem after 2 years of no issue. Now I have it again on a new network.
