ath10k driver

Building

To build ath10k enable these kernel build configuration options, for example with make menuconfig:

  • CONFIG_ATH10K
  • CONFIG_ATH10K_PCI
  • CONFIG_ATH10K_DEBUG (optional)
  • CONFIG_ATH10K_DEBUGFS (optional)
  • CONFIG_ATH10K_TRACING (optional)

The debug and tracing options are optional, but it's strongly recommended to enable to make it easier to debug issues.

ath10k options can be found from location:

-> Device Drivers
 -> Network device support (NETDEVICES [=y])
   -> Wireless LAN (WLAN [=y])
     -> Atheros Wireless Cards (ATH_CARDS [=m])

Loading the modules

The ath10k modules should be loaded automatically in most systems. If that's not happening, first load ath10k_core.ko and then ath10k_pci.ko.

hostapd

ath10k uses the standard upstream hostapd. As of this writing (2013-11-21) it's recommended to use the version from git if using 802.11ac, DFS or ACS.

Building hostapd

When building hostapd enable these configuration options:

  • CONFIG_IEEE80211AC
  • CONFIG_ACS

Configuring hostapd

Example hostapd config to use 11ac VHT80 mode with ath10k:

interface=wlan0
driver=nl80211

ssid=ath10k-test

hw_mode=a
channel=36
ht_capab=[HT40+]
ieee80211n=1
ieee80211ac=1
vht_oper_chwidth=1
vht_oper_centr_freq_seg0_idx=42

vht_oper_centr_freq_seg0_idx is calculated for VHT80 with channel + 6. If you get "set channel failed to set in kernel" error message, most likely your regulatory database doesn't support 80 MHz channels.

To enable ACS set channel to zero:

channel=0

To enable DFS enable 11d and 11h as well as set country code:

country_code=FI
ieee80211d=1
ieee80211h=1

For mBSSID start hostapd using -b switch:

hostapd -g /var/run/hostapd/global -b phy0:ath10k.conf -b phy0:ath10k-1.conf -b phy0:ath10k-2.conf

To remove an interface:

wpa_cli -g /var/run/hostapd/global raw REMOVE wlan0-2

To add an interface:

wpa_cli -g /var/run/hostapd/global raw ADD bss_config=phy0:ath10k-2.conf

See hostapd wiki page and hostapd.conf documentation for more information.
