Reading 802.11 frame

Hi,
i need to read a 802.11 frame with all its informations. Is it possibile?
I have tried with libpcap but seem that the frame header is converted in an ethernet one (by the driver I guess...).

Any suggestions?

Thanks,

Corima

All I can suggest is read through the source code for the 802.11 support. Keep in mind that it is possible to do absolutely everything in the hardware and that the messages sent to the device and received from the device may be simple TCP/IP frames - just as you would send ppp frames to a modem and couldn't really see what the modem was doing with the data (compression, modulation, retransmission ...).
