Hello I am having an ichat connection error. When I try to connect with a video, desktop or audio chat I just get an error saying, Connection Error. I have tried to chat on other networks including at the apple store and it still does not work. I am on a fast broadband connection at home and have a Linksys G/B router with speed booster. The problem does not happen when plugged in by ethernet. My mac firewall is set to "Allow all incoming connections". I have tried a system archive and still no luck. Please if someone could help me with this issue is would be appreciated. I have called apple multiple times and they still can not seem to help. Also other programs like Skype and VNC work. 
Thanks
Thanks
