I have an Atheros 5007EG wireless network card at my hardware
platform. I compiled the kernel(2.6.27) with ath5k built in.
Then I compiled wpa_supplicant with CONFIG_WIRELESS_EXTENSIONS=y
CONFIG_DRIVER_WEXT=y and CONFIG_CTRL_IFACE=y.
Then in my init.rc :
mkdir /data/misc/wifi 0770 wifi wifi
mkdir /data/misc/wifi/sockets 0770 wifi wifi
mkdir /data/system/wpa_supplicant 0770 wifi wifi
mkdir /data/misc/dhcp 0770 dhcp dhcp
chown dhcp dhcp /data/misc/dhcp
ifup wlan0
service wpa_supplicant /system/bin/logwrapper /system/bin/
wpa_supplicant -Dwext -iwlan0 -c/system/etc/wifi/wpa_supplicant.conf -
dd
group wifi
My wpa_supplicant.conf at /system/etc/wifi/wpa_supplicant.conf :
update_config=1
ctrl_interface=DIR=/data/system/wpa_supplicant GROUP=system
Then when I try to scan with: wpa_cli -p/data/system/wpa_supplicant -
iwlan0 and then scan & scan_results, I'm getting no scan results, when
I know there are definitly scan results. Because when I scanned with
Windows, I do get to see scan results.
What is wrong with my configuration?
My logcat output from wpa_supplicant:
