Hi GV,

Thanks GV, I followed your instructions and it worked.


In WinPcap documentation it is given that the #define
remote-ext.h  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,

As explained on this FAQ




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

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

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?
