[Airo-linux-general] Missing frames during handoff

[Anshul J. <wit...@ya...>]

Hello everyone, 

I have two Cisco Ap's AP-1 and Ap-2 in the same ESS
with the same ssid "test" and one mobile STA. The
client adapter is Cisco 350 with airo-linux driver
form sourceforge.net. I am using kismet to sniff
802.11 management frames during handoff when STA is
moving from BSS of Ap-1 to BSS of AP-2. 

Dump file produced by Kismet when seen in ethereal
shows authentication frame and Reassociation Request
frame from STA to AP-2. While the authentication frame
and Reassociation Response frame from AP-2 to STA are
missing. I ran the experiment several times to see if
Kismet is missing the frames, but, everytime the
Kismet showed the same behaviour. When I use different
ssid for two APs I see all the four packets. 

Can anyone tell me what's going on here? Am I doing
something wrong or is this the property of 802.11?
