I have one of those "new" (well, mine's over a year old now) 13" aluminum-cased MacBooks (what is the official name for these anyways, Intel Core-Duo or something?... I digress). I am using the default/included 'AirPort' wireless thingy. All I want to know is: How do I ensure that my AirPort is configured properly to access a 5 ghz wireless band? I just setup my wireless router to broadcast at 5 ghz and I want to make sure my MacBook is receiving at 5 ghz/optimal speed. So, what steps do I take to check this and/or configure it as such?
