The following commands :
sudo wpa_cli bssid myessid 00:C0:CA:35:40:34
sudo ifconfig wlan0 down
sudo ifconfig wlan0 up

switch my computer from one AP to another but I have 2/3 seconds without 

Here, the wpa_supplicant log :
<2>CTRL-EVENT-DISCONNECTED - Disconnect event - remove keys
<2>Trying to associate with 00:c0:ca:35:40:34 (SSID='myessid' freq=2462 MHz)
<2>Associated with 00:c0:ca:35:40:34
<2>WPA: Key negotiation completed with 00:c0:ca:35:40:34 [PTK=CCMP GTK=CCMP]
<2>CTRL-EVENT-CONNECTED - Connection to 00:c0:ca:35:40:34 completed 
(reauth) [id=0 id_str=]

How tell to the driver I want a reassociation to the new AP instead a 
classical association ?

> My laptop works on my wireless network but each time I move from an AP to another one, I have small disconnections (4/5 seconds).
> So, now I'm trying to enable seamless roaming on my laptop (ubuntu server 10.04 / Atheros, driver ath5k).
> It seems wpa_supplicant needs to send reassociation request each time I moves to another AP but its logs shows diassociation and association with full reauth..
> Could you help me ?
