If you're using McAffee firewall, then disable XP's firewall. Go to Control panel to do that. For your Netgear, most such devices if they support UPnP then it's enabled by default. However, you should verify that it is. Telnet into it to find out. I don't have direct instructions for your model, but another netgear model is here http://www.microsoft.com/windowsxp/u...gearMR814.mspx

But then again, if other computers on LAN are running LW fine then perhaps UPnP is not the issue.

Another option is to try deleting your LW Preferences folder whilst LW is closed; instructions here: Point #2 & 3 in Fixes for Limewire (sample image included at bottom of page.)
