You either do not have your ports forwarded correctly, see
www.portforward.com. Which would also include double port forwarding if your cable modem supports dhcp and sends an internal ip address to your router.
or
You have been living under a rock for the past year or so, and do not know that Comcast severely restricts (slows down) all of its customers peer-2-peer downloading.
That's just Comcastic!!!
You don't open your ports in you router by the web interface. So, it could slow down dramaticaly your speed by Transmission.
And second and most possible, Comcast install a new infrastructure to cap and throttle your download and upload speed as ridiculous speed of 1 mb/s in peak hours. Also Time Warner follows the wave and cap his network.
Pray god for hoping find a ISP in our days they don't mess with your cash!
BTW, I come from Canada and Bell are business partners of Comcast, so they did the same thing. Bell are DSL provider with not more than a 5 mb/s DL and 900 kb/s UL. NO ADSL at high speed

. That's very scary. I'm with a cable based ISP and I had 7 mb/s DL and I'm pretty fine and happy
