iChat periodically disconnects About twice a night, iChat will disconnect (though it'll still show me as connected).  After about 10 minutes, it'll realize it's disconnected and bring up a dialog telling me it lost the connection.  I can then close the dialog and reconnect with no trouble.

My computer's network connection seems to be fine throughout this.

Any idea:


What might might be causing this?
How to fix it?
At least how to make it tell me more immediately when it loses the connection?
Your problem might be your router loosing connection temporarily to your ISP.

I use Chax, an extension to iChat which, among other great things, auto-reconnects when connection is lost. Chax is donationware.
