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: 18.104.22.168 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!
