I think the "contact your ISP" for setup should suffice. All advertising should use the word "capable" with an asterisk stating the onus is on the customer to get connectivity. Simply state, connect your network to the supplied jack on the back of your reciever. As Earl has said several times, there are simply too many possible combinations. If customer support is going to help in any way, the end result is a higher cost for support which gets trickled down to all users.
