Reset the router.
Java is 1.6.0_1
Router has LimewireTCP and UCP located in it now - matching LW program port. Win Firewall has Gnutella 127.0.0.1 with matching LW port.
LW changed its firewall settings to manual port with matching all the others.

It had been on UPnP before.
LW bottom left states "LW is connecting to the network" with just one green bar out of the 5 present.
How many firewalls are there?
Anyone else use Websweeper?
