Solution.
1) Open external/dhcpcd/Android.mk and uncomment next lines:
include $(CLEAR_VARS)
LOCAL_MODULE := dhcpcd.conf
LOCAL_MODULE_TAGS := user
LOCAL_MODULE_CLASS := ETC
LOCAL_MODULE_PATH := $(etc_dir)
LOCAL_SRC_FILES := android.conf
include $(BUILD_PREBUILT)
by default they are commented.
2) frameworks/base/wifi/java/android/net/wifi/WifiStateTracker.java
and change:
mInterfaceName = SystemProperties.get("wifi.interface", "tiwlan0");
on your wifi interface. In my case it's wlan0:
mInterfaceName = SystemProperties.get("wifi.interface", "wlan0");
3) verify in init.rc or init.platform.rc dhcpcd service configuration.
In my case it is:
service dhcpcd /system/bin/dhcpcd -d wlan0
group system dhcp
disabled
oneshot
Verify that -d option is set before wifi interface name, otherwise
dhcpcd will not call dhcpcd-run-hooks script.
4) verify system.prop file, should me a line:
wifi.interface=your_wifi_interface
in my case it is:
wifi.interface=wlan0
That's it.
Good luck!
