I continue to debug above issues:-)
Does anyone succeed to use "iwpriv wlan0 monitor 1" to capture raw frames?
I found that when I set monitor mode to 1 or 2, packet can't be received correctly.
Precisely speaking, two laptop are set to ad-hoc mode and ping from one laptop to another on monitor mode 0 without any trouble. After changing to mode 1 or 2, ping doesn't reach.
Again, reset to monitor mode 0, ping reaches again. Could you test if you've already have environment to use hostap and let me know your environment if you succeed to capture raw frames by running wlansniff on mode 1 etc.

My environment:
Hardware: Linksys WPC 11
Driver : Prism2-2002-2-13.tar.gz
Kernel : 2.4.18
Wireless Extension: version 12
Wireless tools: version23 ( iwconfig/iwpriv...)
