I am using dlink DWL-520+ PCI wireless adapter. I have
5 systems and i do ftp transfer between the nodes. I
use ethereal 0.10.8 to capture my packets (with
promiscuous mode disabled). I tried disabling
promiscuous mode by two methods 1)by using -p
parameter in the shell prompt 2) from the ethereal gui
However i find that ethereal captures packets in
promiscuous mode and i could find that ethereal
capture contains packets from all the nodes.
Can any one please let me how to disable the
promiscuous mode in wireless interface

You would do it by contacting whoever supplies or develops the driver for your adapter and ask them whether promiscuous mode is supported by the driver and, if not, ask them to fix the driver so it is. Ethereal doesn't come with drivers for network adapters; we leave it up to others to do that.

(Promiscuous mode on Windows with 802.11 cards tends to cause the cards to go into a mode not particularly useful for packet capture, so, even though you haven't said what OS you're using, I suspect it's Linux or some BSD, rather than Windows, in which case it might be possible to contact the developer directly - but it might still be Windows, in which case you'd probably have to contact the vendor of the card.)
