I have some troubles with hostapd and nl80211, when I try to launch hostapd, this is what I got :

# /etc/init.d/hostapd start
Starting HOSTAP Daemon: Configuration file: /etc/hostapd.conf
nl80211: Driver does not support authentication/association or connect commands
nl80211 driver initialization failed.
hostapd_free_hapd_data: Interface wlan0 wasn't started

Is it due to the wifi driver (RTL8812au) or nl80211 driver? I work on a ARM based device, with iMX6 processor, the driver is cross-compiled.

Something strange, iwconfig works :

# iwconfig 
wlan0     unassociated  Nickname:"<WIFI@REALTEK>"
          Mode:Auto  Frequency=2.412 GHz  Access Point: Not-Associated   
          Sensitivity:0/0  
          Retry:off   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
          Link Quality:0  Signal level:0  Noise level:0
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

but when I run iw list nothing happens.

Can someone help me with this problem?

Additionnal infos:

  • Yocto and custom BSP on the iMX6 board
  • kernel version 3.14.28
  • Linux distribution poky 1.8.1
  • Wifi USB key : Edimax EW-7811USC

According to Arch-wiki, you need to use the deprecated wext driver, to connect you can type the following command:

wpa_supplicant -B -i wlan0 -D wext -c /etc/wpa_supplicant/example.conf
