than rfmon mode or not
As far as I know, yes. As I understand it, from what I've heard, in
promiscuous mode, an adapter will see only packets in the BSS with which
it's associated, whereas, in monitor/rfmon mode, it'll see all packets
on the radio channel it's listening to.
....can we capture 802.11 data in promiscuous
mode
Yes, but you might only be able to capture data frames, not management
or control frames, depending on the driver. (In "host AP" mode, if an
adapter and driver support it, management frames are presumably passed
to the host, so you might be able to capture those packets even if
you're not in rfmon mode. I don't know whether any drivers that support
"host AP" mode do that, however.)
..i am using cisco 350 wireless card.....
On what operating system?
I don't know which OSes have Aironet drivers that support "host AP"
mode, if any - I don't even know whether the Aironet cards support "host
AP" mode, although if Cisco uses them in their AP's, the cards
presumably do - so you might not be able to capture management frames in
promiscuous mode.
I think all Linux and BSD Aironet drivers support promiscuous mode. The
Linux and FreeBSD ones support rfmon mode. I don't know whether the
Windows one supports promiscuous mode at all.
