iMac won't detect wireless-n from AirPort Extreme.

I bought a new AirPort Extreme today and it seems to be working correctly. However, OSX cannot detect the 5ghz wireless-n band. I have the SSID named differently than the 2.4ghz band. I've tried logging into it manually and that does not work either. I've also tried restoring factory settings and starting over but it just wont work. Any ideas?

Here are a couple screen shots.

Thanks for any help.

When apple put out the update for the software to go from 7.3.2 to 7.4.1 it has caused problems with the 5GHz 11n. Luckily i heard about it and have kept 7.3.2 on mine and it operates happily. Do you have the Dual antenna model - that may be different.

Try setting to 11n per pic - see if that helps

Keep in mind with the settings in your pics above the network will default to the slowest speed of any unit connected so if you have an iPhone on the network it will operate at 11g

I was able to get the iMac to detect the 5Ghz network but the speed is absolutely terrible. It also will not connect at times and completely drops the connection randomly.

I set both bands to 11n only and the 2.4 band works flawlessly. I can't get the 5Ghz band to work worth a crap.

Take it back to Apple and ask for 7.3.2 to be put back on it.
