AR5B125: Wifi and bluetooth not working


Recommended Posts

Hi, I come back to you because I have a little problem

I've a dell e7240 running on el capitan

I replaced the intel wifi card by an atheros ar5b125 with bluetooth

Since it worked before.

But I've got some usb problems so I've decided to repair it.

When the machine comes back to me, the bios configuration was reset to default (raid on mode, legacy mode..) so I couldn't boot correctly Mac os.

I set up again the bios parameter so I finally get back the OS

Unfortunately, wifi a'd bluetooth are not detected, it said no device installed.

I launched patch atheros wifi kext but it returns "already patched "


I notice that wifi led never lights up even I move the physical switch. (It lights on before)

The wifi datacard is detected properly in the bios as qualcomm and installed

So what to do?
