Ok, here's the latest.

1. My ISP has confiremd no P2P blocking in any way shape or form.

2. The will not give out the username and password to access the router but they did say it has a built in firewall that could be the issue with the
Vista/P2P combo.

3. I tried dual booting with XP Pro with SP and my limewire speeds returned! However I also tried Azureus and the speed was generally the same and changed a lot.

4. Even though the speeds returned on limewire it still detected a firewall.

5. I also don think the port forwarding helped since I am now positive that my router is supporting UPnP and that the firewall being detected is the one in my modem.

Hope this helps.
