I am relatively new to the iChat world and started using iChat with my cousin and my son and had no issues with either. At the time I was connected wireless to the internet, as they were. I moved location of the mac and hardwired the ethernet connection. I then started failing to get a connection with iChat. It would "see" my cousin, ping them, asking to speak and then crash. I disconnected the hard ethernet connection and went back to wireless and connected fine. The error message just says i had a communication problem.

My cousin's mac is doing the EXACT same thing. To start iChat he has to use the wireless internet connection.

Anyone else experience this issue or have a solution?
