 I see.
 Although I tried to use prism2ethereal on monitor 1, it generated a dump  file to stdout which gets garbled.

 I found new thing....
 When I run "iwpriv wlan0 monitor 1 or 2", the driver looks buggy:  sometime miss associate access point or change essid to "test", ..etc.  Is it possible to use iwpriv monitor 1 or 2 on Managed network?  Are there any restriction to use monitor mode ?

 I appreciate any feedback.
