AirPort Extreme Update 2007-001: Mentions 802.11n!

Looks like Apple has rolled out a new update for AirPort that’s recommended for all Intel mac users (find it here). Now, the first thing on everyone’s mind is: does this have anything to do with 802.11n? There’s no detailed description of the changes other than the standard stuff Apple puts with updates it doesn’t want to divulge all the changes on. That said, I’ve been breaking out the good old command line tool “strings” on recent AirPort drivers as they’ve been coming out, and this is no exception. If you download the update, and then extract the following file:

/System/Library/Extensions/IO80211Family.kext/Contents/PlugIns/AirportAtheros.kext

And then run strings on the AirPortAtheros driver file within Contents/MacOS, in the following manner:

strings AirPortAtheros.kext/Contents/MacOS/AirPortAtheros | grep 802.11

You will see the following:

Wireless Network Adapter (802.11 a/b/g/n)Wireless Network Adapter (802.11 a/b/g)

What does this mean, precisely? Hard to say until someone gives things a shot on an 802.11n network!
