I had a USB ADSL modem which always connected to Limewire fine. Due to a growing network I now have a router, but since obtaining it I get a huge percentage of cannot download, awaiting more sources.

I know this is to do with the NAT firewall, but to be quite honest I have no idea what to do.

I'm not sure how to configure the router. I tried doing the DMZ thing but to no avail, nor does disabling the NAT firewall make any difference.

Can I force the IP address? If so which address is it? The router IP, the computer IP given by the router, or the main address?

I run XP on an upto date machine, share files etc.

Please help me - it is driving me insane!
