Need help with Atheros AR5B91 adapter.

Recommended Posts

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.

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.
