   Yes. I executed /sbin/iwconfig on both LAPTOP and my device. Both
of them displayed "testboard" as essid. This is essid of the initiator
device.

On my device - initiator - first I enable wpa supplicant on my device

  I configured for ad-hoc mode using "iwconfig" on both the devices.
It works fine. If I am not wrong, configuring using iwconfig is same
as enabling wpa_supplicant ad-hoc mode with out security. Am I right?

As I mentioned in my previous mail. wpa supplicant is working in
ad-hoc mode without security. I am facing problem in WPA-NONE.

How to configure and test WEP security in ad-hoc mode? please tell me set up.
