I Called Cox Cable and they informed me that they do not block anything higher than 1900 so using anything higher than that number in the port forward box should work fine. I also noticed that a lot of the instructions for port forwarding refer to routers, I do not have a router, I just go directly into my modem. I still can not get beyond the 1 bar and the "Limewire is connecting to the network" message when I try a search.
The support tech at Cox cable said it is not on their end. Whats weird is people with ISP's other than Cox are having the same problem.
Help please, I need my LimeWire.
