By "classical roaming", I was meaning of reducing the time of moving from
one AP to another. Now, when I lose connection to the AP, I'm losing
approximately 5 seconds for searching a new AP and then one or two seconds

One solution to reduce the time of authentication is CCKM.
Do you have a solution to reduce the time of research ? Is there a specific
configuration of wpa_supplicant?
