Changing ports isn't necessarily going to make your downloads faster
If people are having trouble with an ISP blocking certain ports, we tell them to try a port in the range 49152 - 65535. Port 64049 is one that a few people use. You can try some higher ports in this range if you like, see if it makes any difference.
