我正在尝试让 AR9271 芯片组在 debian (Raspbian) 下工作。
sudo lsusb | grep Atheros
Bus 001 Device 005: ID 0cf3:9271 Atheros Communications, Inc. AR9271 802.11n
我已经安装了firmware-atheros。
lsmod | grep ath
ath9k_htc 56078 0
ath9k_common 21766 1 ath9k_htc
ath9k_hw 415436 2 ath9k_common,ath9k_htc
ath 18741 3 ath9k_common,ath9k_htc,ath9k_hw
mac80211 532034 1 ath9k_htc
cfg80211 427855 4 ath,ath9k_common,mac80211,ath9k_htc
配置文件
iwconfig wlan0
wlan0 IEEE 802.11bgn ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=20 dBm
Retry short limit:7 RTS thr:off Fragment thr:off
Encryption key:off
Power Management:off
但似乎AR9271使用的是ath9k驱动程序而不是ath9k_htc？
airmon-ng start wlan0
Interface Chipset Driver
wlan0 Atheros AR9271 ath9k - [phy1]
(monitor mode enabled on mon0)
当我尝试改变频道或其他东西时，问题就出现了。
sudo iwconfig wlan0 channel 1
Error for wireless request "Set Frequency" (8B04) :
SET failed on device wlan0 ; Device or resource busy.
如果我尝试启动 airodump-ng 我得到：fixed channel mon0: -1
我的系统：
uname -a
Linux raspberrypi 4.4.13-v7+ #894 SMP Mon Jun 13 13:13:27 BST 2016 armv7l GNU/Linux
我想这是固件问题？
