OK - so I cannot connect at home anymore after doing the Gnutella change in the Win Firewall. So I restored to default in the Win Firewall and still NADA!

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?

Try this version of Java instead, some people have had trouble with 1.6.0_01.
Use the offline installer & remove your current Java version before you install this one

Try port forwarding for the Linksys, the instructions are here.
Port Forwarding for the Linksys BEFSR41
Don't forget to set up a static IP address first. LW's listening port, port in the 'manual port forward' box & port forwarded within the router must all be the same number.

In the meantime. I noticed the test site is for port 6346 but my LW and applications are on 2740.

Will that make a difference on running LW.

The test site is just for LW's default port (useful to see whether the default port's being blocked...often by an ISP).

AFAIK Qwest don't block LW, but maybe that's changed?
Try changing ports. In LW tools > options > advanced > firewall config. Change LW's listening port to 64049 (or something in the range of 49152 - 65535). Apply to save a change.
Any ports forwarded within a router & port in the 'manual port forward' box will also have to change.

Installed Comodo Firewall. Disabled Win Firewall. Allowed LW to be a "server" in the Comodo's settings.
Now the router does not have LW - have no clue what happened to it. There one minute - gone the next.

This is how I've allowed LW thru my Comodo firewall (followed instructions posted on the Comodo forum). Click on the link below.

Your router has a firewall, which is why I suggested port forwarding...did you try that?
