Replaced my 5th Gen Airport Extreme router with a Netgear Nighthawk AC1900 router (model R7000).
Popped an ASUS PCE-AC68 in yesterday on Mavericks.
It works OOB, recognized as a Third party card. To get it recognized as Airport Extrem. I had to hex edit /System/Library/Extensions/IO80211Family.kext/Contents/PlugIns/AirPortBrcm4360.kext/Contents/MacOS/AirPortBrcm4360
30 6B 10 00 00 75 0D
30 6B 10 00 00 90 90
As others recommended in various posts.
In Network Utility, it recognizes the card as 600mbps (over 450 before). However, in System Info -> Wifi, we see:
Current Network Information:
PHY Mode: 802.11ac
Country Code: US
Network Type: Infrastructure
Security: WPA2 Personal
Signal / Noise: -45 dBm / -83 dBm
Transmit Rate: 405
MCS Index: 7
Transmit rate = 405, which is the same as I get on my other hack with an N card (this is still higher than I got on the old router as the new router is faster).
In each case the router is only about 15 feet from the computer, so I don't think it's a signal issue.
In comparison, on my Macbook Pro Retina I get transmit rates up to 1035 (usually at 878 however). Which is terrific.
Either way, my actual transfer rates are about the same when moving big files around.
Anyone have any tips on getting it to recognize at 1300mbps? Or, more importantly, register a higher transfer rate?
