Two issues:

1) Screen flickers. I think it may be a heat issue. When I'm busting into four cores running at the same time, all programs opened up, and it has been running all day it can get kind of hot. This is when the screen flickers begin. A restart will take them away for a good amount of time.

2) Airport almost always disconnects itself every time I open FireFox and then reconnects several times during my Internet usage. Sometimes at night it never works at all and I have to use my laptop to get online. Very annoying. Especially for an online poker player! >

I am planning on calling AppleCare about this. But i was wondering if anyone has had similar problems or if anyone has any solutions...

Call AppleCare - I've heard some problems with the 27" iMacs and this might be part of the issue. Best to get it checked sooner.
Hope that it all works out for you!

That'd be a real drag while you're at a table in a cash game.
Had my service go down once as the chip leader, top 4, looking at a $4k payout.
Took 'em 2 days to get my service back running. The words to describe me at that moment are not allowed on this forum.

I'd ask if you're wired or wireless? If wireless are you using WPA instead of WEP?

I know the feeling. It recently happened to me. Had a full house from the flop about to go all in when my service shut out and closed the program. I folded. Now, granted it was only a low stakes table but STILL!

I am wireless. WPA.

Only know to throw out some questions here.

Does your router have the latest firmware updates?

Are you broadcasting the SSID? You should be if you're not.

Have you tried changing the channel?

How far are you from the router - try repositioning the antennas on the router - or move it's physical position some (for instance if it's sitting right next to another device or raising it up 12")

And also check out cwa's FAQ

Yes. All up-to-date.

Nope.

Yes. Problem continues.

I'm upstairs. The router is downstairs. Works fine on my Dell laptop which is upstairs as well. It also works fine for my roommates MacBook Pro. I've tried re-positioning the router so it's a little closer to the stair but that doesn't help.

Thanks for the FAQ. I'll check it out.

Definitely turn on broadcasting the SSID. That one item could be it. Have seen quite a few reports that just would not function properly without it.

There really is no reason not to when using WPA. Not broadcasting really only keeps your neighbors from knowing the network name. It's not going to keep anyone sniffing from finding it.

Being upstairs from the router also causes a lot of issues.
