Are there any USB wireless adapters that will operate in Promiscuous
mode ?

I have a Zydas chipped USB wireless adapter and that only appears to
recive traffic for its MAC address and broadcasts.

Using Ntop and Windows 2000.

Sorry for the double post, my news server was a bit slow updating last

I've never seen a wireless network card that can support promiscuous mode.
If your goal is to create a network bridge then this can still be achieved.
Using Windows XP I was able to get around using promiscuous mode by forcing
my network adapter in my network bridge into Layer 3 bridging
mode(promiscuous mode means layer 2 bridging). Basicly it took TCP/IP
packets and forwarded them between segments, with the source MAC address of
packets passing through the bridge always showing up as the MAC address of
the network bridge.

Email me if you'd like to know how to force Windows XP's network bridge into
layer 3 mode.

Am I guilty of missusing a term then ?

Presumably there are wirelsss cards that will see all packets, is that
what is refered to as RF Monitor mode ?

You are probably right. I dont know that much about wireless networking, but
I've read about an RF monitor mode, where the card listens to a channel and
saves what it decyphers. I've presumed wireless networking cards are
different to standard ethernet cards in that they dont hear everything on a
channel, as the transmission of 1 client might not be heard by another, but
heard both clients can still be in range of the access point. It could be
possible to capture every packet sent from a wireless access point.
