Thank you for your suggestion
Also, I'm sorry reply late.

>Ubuntu I believe uses a different network manager
I am aware network maneger is used in GUI environment, and, should not be
used on the server without a GUI
Am I wrong?



>Try change auto wlan0  to allow-hotplug wlan0.
I changed
# auto wlan0
allow-hotplug wlan0

After that, I started wlan0
ifup wlan0

Message is displayed
RTNETLINK answers: File exists
Failed to bring up wlan0

wlan0 had started.
ifconfig
