OK....I tried to disable my XP firewall and I also tried the directions for allowing exceptions and putting the right port # for TCP and UDP connections. My router settings have never changed...it is the Actiontec 1524SU and my ISP is Qwest....as far as I can tell Qwest is not blocking anything at all. I do see the firewall icon and it doesn't go away after I disable XP firewall. I am running AVG Free but no firewall. The port test does not work so I put in port 6346 and that didn't work either. My other computer which is a laptop is runing side by side this system and running 4.12 no problems. I have tried to duplicate all of the settings I have on the laptop but still no luck connecting. I went through my actiontec setup and nothing is different. I get one green connection bar and it says connecting to LW but never gets there....no other error messages.
