Well I have spent hours on trying to figure out why my instant messenger will not work and I have tryed just about everything I can think of. Reinstalling MSN, yahoo, AIM. Every tyme I get an eroor message saying there could be a problem with tha proxy server or something? I've tryed troubleshooting. Well It worked at my friends house before I got it with a cable connection. Mine is wireless comcast using a router that is upstairs. Is that why its not working? Cause my brother also has a wireless using tha same connection, and It works fine for him. I've gone into the router settings, TCP/IP properties, messenger settings, enabled it in my firewall, and I've looked on tha internet! I really want to figure out why this doesnt work, and finally be able to talk with everybody.
