Here are the details I know, my computer is secondhand from a friend and not really top of the line so I'm not 100% on all of them.

1. Windows XP
2. Windows firewall.
3. 20 GB
4. 6 GB
5. cable
6. Motorola modem from shaw.
D-Link WBR-1310 Router
7. Home
8. Limewire 4.14.10 Pro
Java 1.5.0_06
9. Shaw
10. My test worked.
11. I have an XBOX 360 on the same connection.
12. New problem.
13. Yes, the brick wall is there.
14. I have tried both.
15. AVG anti-virus.
16. Canada

Also I contacted my ISP and they said that they don't block LimeWire, and when I hardwire my computer straight into the modem it works fine. This is why I think its the router, but any other ideas are much appreciated.
Thanks
Any help or ideas are appreciated.
