got my new high end 21.5" imac this morning. only had about five minutes with it because i had to run to work. So the wifi isn't working. My network and others show up and it accepts my password. When it tries to connect, I get that symbol with the "!" in it. I was able to connect once I hard wired into the ethernet port. I'm mostly posting this to let people know about a possible issue with the new imacs. I'm guessing I'll have to take it in, unless someone knows an answer for it. Are there any software updates or anything that might fix this? Haven't checked that yet.
