Apparently all the extra services on my tv, such as Netflix and Amazon, came through my internet via wireless on my last router. The standard tv comes through the cable. That is how I understand it? The new router hasn't changed the standard tv, but I can't get any of the extra ones.
Coincidentally, I am getting a new box, presumably V6?, so everything will come through the router via wireless, I believe? Perhaps I should wait and see if the new box has a place I can put details of the router and password etc.?
