Re: [PHY] Adaptive equipment
Hi, Thanks adrian for the answers ! I wonder who provides the ATH HAL (for 93000) ? Qualcomm ? The linux ath9k do not use any HAL, so does Qualcomm provide an HAL only for BSD ?

Re: [PHY] Adaptive equipment
ath9k has a hal, it's just not called "hal". it's called ath9k_hw. -adrian On 26 April 2017 at 02:41, Valentin VERGEZ wrote: > Hi, > > Thanks adrian for the answers ! > > I wonder who provides the ATH HAL (for 93000) ?

Re: How well is the Atheros 9287 supported?
hiya, AR9287/AR9227 should work fine. I even have laptops using it.
