[Winpcap-users] why WinPcap is not capturing packets formmywireless PC card - Thanks Gianluca

[Steighton_Haley at McAfee.com]

The driver for your wireless adapter most likely does not support
promiscuous mode operation.  This is common.  It is covered in the FAQ.
Please read it.

	Hi GV,

	Thanks GV, I followed your instructions and it worked.

	 

	In WinPcap documentation it is given that the #define
PCAP_OPENFLAG_PROMISCUOUS of remote-ext.h
<http://winpcap.mirror.ethereal.com/301a/docs/remote-ext_8h-source.html>
is deciding our device should be in promiscuous mode or not. But in my
application in pcap_open_live () when I gave 0 and DISABLED PROMISCOUS
MODE,  my program run and I got output. 

	 

	Your reply says that while using WinPcap our application should
disable promiscuous mode. But most network sniffers work in promiscuous
mode only. So I am confused with this. Please clarify

	 

	Thanks in advance,

	 

	vimal

	As explained on this FAQ

	 

	http://www.winpcap.org/misc/faq.htm#Q-16

	 

	due to the limits of the Windows OS, you can have problems
capturing from Wireless adapters: some of them don't work at all, some
of them work only if promiscuous mode is disabled. 

	 

	Have a nice day

	GV

		Hi,

		 

		I tried to capture wireless packets using the basic_dump
example. I could capture Ethernet packet. Even though it is detecting my
wireless driver it is not displaying any result.

		 

		I got this result when I tried with a NETGEAR WAG511 PC
card.

		 

		1. \Device\NPF_GenericDialupAdapter (Generic dialup
adapter)

		2. \Device\NPF_{71FFDFA2-557E-48C7-AE0E-F7F046395F27}
(NETGEAR WAG511 802.11a/b/

		g Dual Band Wireless PC Card)

		3. \Device\NPF_{345D2B1C-EAEB-437B-AB9A-D848EAEF7DEA}
(NDIS 5.0 driver

	
)

		Enter the interface number (1-3):2

		 

		listening on NETGEAR WAG511 802.11a/b/g Dual Band
Wireless PC Card...

		 

		how to capture data from a wireless card?

		 

		Regards,

		vimal
