<pre><font size="2">An important difference between Monitor mode and Promiscuous mode is that in monitor mode you are only a passive receiver and cannot send any packets out.<br>In promiscuous mode the device can also transmit packets (on the network it is associated with). <br>
<br>Another thing, which I am not too sure of so don't take my word for it, is that in Promiscuous mode one might be able to receive packets from other SSIDs that are on the same channel. This might be vendor-dependent though.<br>
An option like this could be useful, for example, if you want to be associated with an AP but at the same time receive traffic on an ad-hoc network on the same channel.<br><br>Nadav<br><br><br><br>On Sat, May 17, 2008 at 5:28 AM, Brad Midgley <<a href="http://lists.openmoko.org/mailman/listinfo/community" target="_blank">bmidgley at gmail.com</a>> wrote:<br>

Monitor mode makes the card receive everything going over the air, not<br>just packets with its SSID, while promiscuous mode allows you to<br>receive IP traffic not destined for you (in a network connected with a<br>hub, when you use a switch, things get interesting with ARP hijacking<br>
and the like)<br><br>Cheers,<br>Federico</font></pre>
