Dear Dan,
I don't start the D-Bus for WIFI when am running the NM in my embedded
device. I don't know if there is the problem for NM or device driver. But I
can use iwconfig and dhclient to set wifi to connect to Internet. I also
know the device driver may be the problem for iwioctl since there are some
warning as shown in /var/log/message, I also have checked NM is always
calling sys/ioctl.h. My questions, if I don't fix the device driver, Is
there a way to fix this problem through change some codes in NM?, or there
is no way in the NM side. The wifi device is Atheros AR6000,Thanks for
your suggestion.

According to the documents and your notes, I have setup
/etc/NetworkManager/nm-system-setting.conf in the embedded device
This is as follows
$cat nm-system-setting.conf
[main]
plugins=ifupdown,keyfile
[keyfile]
unmanaged-device=mac:00:21:e8:70:c8:bc
[ifupdown]
managed=false
Then I check the D-BUS for wifi, but the the D-bus for wifi is still not
coming out, which still has informations as follows:
device list is /org/freedesktop/NetworkManager/Devices/0
Device eth2 is activate
No
device list is /org/freedesktop/NetworkManager/Devices/1
Device wlan0 is activate
