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 https://www.insanelymac.com/forum/topic/285468-need-help-with-atheros-ar5b91-adapter/ 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 https://www.insanelymac.com/forum/topic/285468-need-help-with-atheros-ar5b91-adapter/#findComment-1878389 Share on other sites More sharing options...
