Salut rhschumaker,
now you'll test switching another port like 1234 (my favorite

) to see if your ISP (internet service provider, yours is Charter) block Gnutella ports (6346-6348).
If that doesn't work, we'll see if LW is the problem by downloading another Gnutella app free of spywares:
www.bearshare.com/lite/
If bearshare doesn't work, the problem is probably your ISP blocking the Gnutella traffic, call them!
Bonne chance
