wws12 Posted January 5, 2013 Share Posted January 5, 2013 Hey- I bought and installed a Atheros AR5B91 adapter with a mini pci-e to pci e adapter and it works ok under Windows 7. If I boot OS X, I get a Failed to load kext com.apple.AirPort.Atheros21 error. THere is also a Failed to load IO80211family kext error. Can someone offer advice on how to fix this? It is appreciated as always. Link to comment Share on other sites More sharing options...
LatinMcG Posted January 6, 2013 Share Posted January 6, 2013 do u use patched dsdt ? irq conflict can cause this. what motherboard is it ? ive tried 3 different AR5B91 and all worked. sounds like permissions issue. i fact i just put one in asus P8Z77-V LX and no issues. ( i have removed irqs in dsdt with patcher) ahh see u fixed it. . legacy kernel issue. http://www.insanelymac.com/forum/topic/284807-will-this-card-work-with-ml-oob/#entry1878390 Link to comment Share on other sites More sharing options...
