I tried both ports, 1720 and 1755 and no change in download speeds. I called rogers to complain and the tech guy said to me it must be my settings in my firewall cause everything looks good on his end and this is the first of he has heard of this bandwidth blocking. I sure hope rogers decides to pull off the cap cause if not I'm going back to bell and I'm sure others have already and more will if they don't.
