02:00.0 Network controller [0280]: Atheros Communications Inc. AR9462 Wireless Network Adapter [168c:0034] (rev 01)

I am trying to get this card working in my Samsung NP550P5C laptop with Mountain Lion 10.8.2. It is a combo wireless / bluetooth card but I assume that the wireless device behaves the same way as in a normal non-combo card.

So far I am able to load AirportAtheros21 as well AirportAtheros40 by making vendorid and productid replacements based on the 10.7.4 IO80211Networking kext.



Since AirPortAtheros40 is loaded first and I see the following in the kernel log:

start [/SourceCache/AirPortDriverAtheros9380/AirPortDriverAtheros9380-431.14.10/src/common/lmac/ath_dev/darwin/AtherosController.cpp:962] load failed

I remove the ids from AirportAtheros21 so it doesn't load on boot.

Now I have just the following loaded:



So far so good...

However I don't know how to proceed now that the AirPortAtheros40 kext is loaded however no Wireless Interface is available in SystemPrefs.Network.

Any hints or guidance would be appreciated.

I have tried deleting and reconfiguring interfaces by removal of /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist

Also tried removing the following:

/Library/Preferences/SystemConfiguration/NetworkInterfaces.plist

But this was clutching at straws with no net effect....

Any one able to help ?

I am looking now at making DSDT edit for this problem (will definitely need help now!)

Need to confirm something - when looking at IOREG output my wireless card is it this one :



If so...

Should I need to edit the following section in DSDT:



Now I plan to proceed as per here and have the following patch:

Device (PXSX)
			 {
				 Name (_ADR, Zero)
				 Name (_SUN, One)
				 Name (_PRW, Package (0x02)
				 {
					 0x09,
					 0x04
				 })
				 Method (_DSM, 4, NotSerialized)
				 {
					 Store (Package (0x0B)
						 {
							 "AAPL,slot-name",
							 Buffer (0x08)
							 {
								 "AirPort"
							 },
							 "device-id",
							 Buffer (0x04)
							 {
								 0x34, 0x00, 0x00, 0x00
							 },

							 Buffer (0x08)
							 {
								 "AirPort"
							 },
							 "model",
							 Buffer (0x35)
							 {
								 "Atheros 9462 802.11 a/b/g/n Wireless Network Adapter"
							 },
							 "subsystem-id",
							 Buffer (0x04)
							 {
								 0x12, 0x41, 0x00, 0x00
							 },
							 "subsystem-vendor-id",
							 Buffer (0x04)
							 {
								 0x4D, 0x14, 0x00, 0x00
							 }
						 }, Local0)
					 DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
					 Return (Local0)
				 }
			 }

This is based on device ids taken from Linux where the following is seen:

02:00.0 Network controller [0280]: Atheros Communications Inc. AR9462 Wireless Network Adapter [168c:0034] (rev 01)

I have added and compiled. Any advice.
