Want to capture WLAN packets

Hi All,

I want to capture 802.11 WLAN packets from Ethereal. But when I tried with
NetGear wireless card, I was able to capture Ping packets

But It was not showing any WLAN packets like

1) Beacon frames

2) Authentication request/response

3) Association request/response

So please any buddy can tell me how to capture these packets.

Hi Madhur,

have a look at http://wiki.ethereal.com/CaptureSetup/WLAN for
information on how to set your card to monitor mode. To get correct
Assoctiation IDs, you could apply this patch: http://www.ethereal.com/

If Wireshark won't work, Kismet probably won't work, either.

If Kismet works and Wireshark doesn't, this is arguably a deficiency
in libpcap/WinPcap. Send me what OS and version of libpcap/WinPcap
and Kismet you're using so I can see if that deficiency can be
remedied.

Step 1: do *NOT* run Windows on your machine. NDIS (which is what the
WinPcap driver uses), and the standard 802.11 drivers on Windows, have
no mechanism to allow a driver or application to request that it see
802.11 management frames.

Which NetGear card do you have? Linux and/or one or more of the
free-software BSDs might support the card and support putting it into
monitor mode. (Note that, in monitor mode, most if not all network
adapters do *not* support being associated with a network, so you can
only do passive traffic capture.)
