wpa_supplicant and IAPP

Hi,

I have a network compounded of two Access Points and a RADIUS server. 
Everything goes fine and I succeed to connect to the AP I want. However 
I would like that my Mobile Host switch quickly from an AP to another 
(less than 1sec).
When I want to switch from one to another AP I use :

"wpa_cli bssid my_network wanted_bssid
wpa_cli reassociate"

but then it needs between 2 and 5 seconds to connect. Therefore I am not 
sure it is the good way to do it.
I am looking for doing a pre-registration to the new AP then a quick 
handoff.


The APs are Alfa AIP-W610H and they are using IAPP
The mobile host is an Ubuntu 10.04 with Atheros wireless card and ath5k 
driver
I use wpa_supplicant 0.6.9 and here is its configuration file :

"
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
eapol_version=1
ap_scan=1
fast_reauth=1

network={
   ssid="Gostai_2"
   scan_ssid=1
   key_mgmt=WPA-EAP
   proto=RSN
   eap=PEAP
   identity="identity"
   password="password"
   ca_cert="/etc/ssl/certs/my_cert.pem"
   peerkey=1
   proactive_key_caching=1
}
"

Thanks for your help


Best Regards

Benoit
