Not sure if the origional post is just out of date or something, but i've been searching for solutions to my lack of connectivity and none of them seem to be right. This one involves deleting the preferences folder, but I can't find one anywhere. Another had you delete and replace the Gnutella.net file, which also was nowhere to be found. I went under Tools -> Options -> Advanced in Limewire and set the Listen on Port and Manual Port Forward to 59812 and Listen on port to the same just like portforward.com said to but that didn't work either.

Currently my internet setup is as follows:

ISP: Timewarner (Roadrunner Broadband)
Cable comes into house, connects to cable modem, which connects to Netgear wireless router, which connects to upstairs computer hard line, and my downstairs computer wireless. Now Norton Antivirus is on the upstairs computer, but I wouldn't think it would affect me since I'm not connected through that computer, just through the router which the cable modem is hooked into. Azureus works fine for me, just Limewire is giving me problems.
