On a related note, I noticed the following behavior when using the hostap driver.
1. I've configured my D-Link NIC to operate as a station using the command
iwconfig wlan0 essid new1 mode Managed
and it associated fine with another AP (whose essid is new1).
2. Prior to this I used prism2_srec to upgrade my NICs firmware to RF010702.HEX
3. I then put my NIC in monitor mode to sniff 802.11 packets using Ethereal using the
iwconfig wlan0 mode monitor
Ethereal works just fine and picks up all the .11 frames
4. I now tried to associate another STA with the AP. Unexpectedly, my NIC card that
was in monitor mode started replying to probe requests from the STA. The STA got
confused and sent .11 authentication request to my NIC card rather than the AP.
How can I prevent my hostap controlled NIC card behaving as an AP when it is monitor mode ?
Ideally, I would like to use my hostap driver as a passive 802.11 monitor and not behave as an AP.
