Hello everybody,

I finally managed to install OSX on my MSI CR700x laptop. Everything (well, almost…) works fine, except for the built-in Atheros AR9285 Wireless Adapter, on which the 802.11n connection is not working at all. (it acts like a b/g adapter with the difference, that it doesn’t even connect to n-enabled routers, even when the AP is set to be compatible. (bgn or gn mixed mode)

When I search for a 802.11n network, it tries to connect with DHCP, but after a period of time instead of connecting it gets only a self assigned IP.(169.XXX etc.) If I select the DHCP with manual IP-adress option, and enter an IP corresponding to the router IP (192.168.1.1XX), it says that it’s connected, but there’s no internet connection at all. Same goes for it when I try the whole manual connection. The encryption may not be the problem(WPA2), because when encountering this problem I tried connecting to our n network with disabling security, or enabling only WEP, but connection was still not working. When the router is set to b/g mode, WPA2 works like a charm.

I’m using currently this kext: http://www.osx86.net...do=file&id=2031
(tried also a few(2-3) others but those gave KP or didn’t work at all.) By the way, I had the same problem with Snow Leopard 10.6.3!(with other kext)

My specs are:
Installation method: iATKOS L1, (setup has been booted with "-v npci=0x2000" to avoid PCI Configuration Begin Error), Mac OS X 10.7.1
Model: MSI CR700X-023HU
CPU: Intel Celeron Dual-Core T3000 @ 1.80 Ghz
Chipset: NVIDIA MCP79

The System Information gives the following information:(my router is now set to 802.11bg mode)

Software Versions:
  CoreWLAN: 2.0 (200.46)
  CoreWLANKit: 1.0 (100.43)
  Menu Extra: 7.0 (700.42)
  configd plug-in: 7.0 (700.57)
  System Profiler: 7.0 (700.3)
  IO80211 Family: 4.1.1 (411.1)
  WiFi Diagnostics: 1.0 (100.26)
  AirPort Utility: 5.5.3 (553.20)
  Interfaces:
en1:
  Card Type: AirPort Extreme  (0x168C, 0x1089)
  Firmware Version: Atheros 9285: 2.1.14.9
  MAC Address: 00:25:d3:0b:48:04
  Locale: Unknown
  Country Code: GB
  Supported PHY Modes: 802.11 b/g/n
  Supported Channels: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13
  Wake On Wireless: Supported
  Status: Connected
  Current Network Information:
Szappan:
  PHY Mode: 802.11g
  BSSID: 00:27:19:dc:33:90
  Channel: 6
  Country Code: GB
  Network Type: Infrastructure
  Security: WPA2 Personal
  Signal / Noise: -48 dBm / -96 dBm
  Transmit Rate: 54

While reading this, I noticed, that among the supported PHY modes, 802.11n is listed, and the more important thing, that among the AR9285 Network card specs as well under the router specs the country code is GB (I assume this is Great Britain), while on the router configuration page (TP-Link TL-WR1043N, if this matters...), under Wireless settings, country is set to Hungary, and my ISP is also Hungarian. Also, when booting in verbose mode, I get a message like this: "ATHR: unknown locale: 60" (this doesn't cause any KP or similar)

I hope somebody could help to find a solution...Thanks in advance!

my ar9281 aka ar95B1 works oob (tried 2 brands both worked) .
the ar9282 aka ar5bxb92 didnt work properly for me and had similar issues. seems its the rom doesnt fully interconnect with driver.

u can try the dsdt ar9285 fix but i doubt it will work.
other thing is the smbios.plist . what model and info in it makes difference..

Hi.

Firmware 2.x.x.x - does not support connect N-routers for ar9285 cards.
To fix problem you need install driver whis Firmware 4.x.x.x

Hi,

give a try with the attached kext.

For unknown locale, you can fix this by setting your regdomain to 0x00 with this http://rghost.net/2603267
You need to do this on windows and allow unsigned driver with http://www.ngohq.com...e.php?page=dseo

More infos here : http://www.tehnari.ru/f25/t43930/



Good luck

Good luck

sometimes u can try the actual countrycode u are in also.
i fiddled with this and made card unstable with somesettings. but that didnt fix the firmware issue in 10.6.5 days with ar5bxb92.

on that note. the dsdt fix for it fakes the 1089 to 8F (apple subsystem for this card ^)

is this subsystem id 1089 a half card ?? or full ?

id just go out and buy AR5B91 full size and full pins (none missing @ $8 on ebay) and works %99 of times on hackbooks i ve done with 10.6.8.

Hi,

Thank you all for your help, I tried Skvo's suggestion to use a driver with 4.x firmware, and the kext from osx86.net works like a charm, with N compatibility and full speed!!! I decided not to bother that unknown locale error, because in reality it doesn't cause any problems and I don't want to risk messing up the whole system because of it...(btw, with this kext country code changed to US)

So thank you all again, you helped a lot!!!!! :D
