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.
