I've been using the T-P Link WDN4800 (AR9380) under 10.8.2 for the last month, the card is detected as an Airport card, and works, but I'm unable to use any 5ghz channels over 64. The card doesn't have any support for channels over 64 in (Wi-Fi) System Information. The Locale and County Code are both empty.
In windows 7 I'm able to use every available channel even ones illegal in the US with the CommView application when scanning, and because of the card regdomain (I don't know what its set to) i'm unable to change with RCU.exe because the application says the card doesn't need it to change anything.
Do you know how I might be able to add these extra channels, with a DSDT edit or something else?
Like I said the card work OOB just with very limited 5ghz channel support. Its hard to setup a decent wifi network in my area because of all the interference and only allowed to use up to channel 64 kinda ties "my hand behind my back" so to speak with setting up my router to perform on a frequency with the least amount traffic.
Even though the card works, do I maybe need a DSDT patch to make it look exactly like an Apple AR9380? Does apple even use this Atheros card in real Macs? No right they don't have any 450m Airport card do they?
As always thanks,

PS. Maybe I can setup SMBios as iMac 2011 model and use the wifi firmware update to remove the world mode regdomain the AR9380 is currently using, and hopefully change to what ever apple uses for there Atheros wi-fi cards?
Wishful thinking i know, i'm sure to have a brick after that, if it even allow the update... =)
