ichat connections
The problem you are coming across with your ichat problems is due to your router. my advise, BUY A NEW ROUTER.
Either your router is old and needs to be updated anyway. or your router is set up to block certain programs or connections. If you have a new router, then change that router for another router like the airport express or extreme. It's a simple fix. Avoid saving $20 on a router and get a airport and that will fix your ichat problems. All that , connect/disconnect multiple times, unable to video chat, always cuts off while on the internet, looses my password, takes long to connect, all of that has to do with the ROUTER. BUT A NEW ROUTER and if you already bought a new linksys or netgear, GET A AIRPORT to assure you'll get ichat to work properly. They work with PC and Mac's.
Good Luck
Or hassle thru changing ports and that should help, but you will be only patching the problem for THAT particular software. My brother had the same issue. All in the past now.
