I have 2 computers and a linksys wireless router. One computer will connect the other won't. I trier disabling the firewall and still no luck. I also tried everything recomended in the fourms and no luck. Anyone with anything to help?

This works for me:
On each machine, set a fixed local IP, and a different LW port.

In the Linksys setup->Advanced->Port Forwarding, you can then enter the matches you set.

So computer A, say, Local IP 192.168.1.2 might be mapped to use LW over port 6346; computer B Local IP 192.168.1.3 uses LW over port 6348, computer C might be set for 192.168.1.4 to use LW on port 23456 (or whatever port you choose that isn't used by other apps). LW works on most ports--6346 is just a suggested default.

Then in the Linksys set up, I forward port 6346 to 192.168.1.2 , check TCP and UDP, and check 'enable'

port 6348 is mapped to 192.168.1.3; port 23456 gets mapped to 192.168.1.4, and so on.

This set-up shouldn't be necessary, but it works on my LAN so all the family can be running whatever p2p program they want. They just have to know which port their machine is allowed, and set the app to listen/force that port.

If each machine wants to run a firewall too (redundant since they are already behind the router), they just need to open "their" port in their firewall settings.

IOW--set a unique path for each machine to connect LW to the internet.
