Just got home from the Apple Store a bit ago after trying to get my fraying power adapter replaced (I'm a month over warranty so I have to save up $79 for a replacement) and tried logging on to iChat... but it keep timing out! The exact message being "The connection could not be completed because it timed out. Try again." Safari and Mail both work well, but iChat, Yahoo! Messenger, MSN Messenger, LimeWire, and Transmission will not connect. I don't mind the last two as a seldom use them, but definitely peeved about the chat programs. Using my building's built-in WiFi network, but this is unrelated to the problems I've been having with it. Any ideas? I appreciate any help.
