I monitored traffic on wireshark, AP is not sending dissociate frame. It is the driver/card at wpa_supplicant end initiating the the dissociate. <br><br>One observation is when i run command "iwconfig wlan0" while wpa_supplicant is running , i see the frequecy/channel varying. My AP works at channel 6 so i think station card should be tuned to same channel, but instead i see it changing continuosly.<br>
<br> Is it a correct combination of wlan0 and wext to be used to make it work? or i should try madwifi instead?<br><br><br>- Paresh<br><br><div class="gmail_quote">On Thu, May 21, 2009 at 12:51 AM, Dan Williams <span dir="ltr"><<a href="mailto:dcbw@redhat.com">dcbw@redhat.com</a>></span> wrote:<br>

</div>You'll have to find out from the driver why the disassociation is<br>
happening. It might also be triggered by the AP itself, so you could<br>
also sniff packets from the air to figure out if the AP has<br>
disassociated you for some reason.<br>
