The installer point of view = The FREE installation list has been growing. The money offered to install a much more complex system has remained flat in many areas. At the same time installers have, one way or another, been goosed to move through more jobs per day. So probably this installer just knew if he began the internet setup & ther was a problem it would cost him time he did not have,,,and wasn't getting paid to expend anyway.
Or he didn't know how.
