That's a real situation, that's a common, but is it fine?
Is it logical what when I (hostapd client SA1) change AP to other I
will not say to old AP good bye? That's like with girlfriends. If u
wana change it u need to say first one good bye. Common in real life is
what u change it before u say good bye and after timeout she know what
u leave, but is it correct? I don't known.

I don't know too much about that standards. I am at first tester, user, and
at last a developper...

Is a problem to add may be few lines (IMHO: 2 max 3) to send deassoc
req. before change ESSID and try to find a new AP?

MP> U also need other network elements such as Radius server etc.
Radius server for authentification is nice, but that's don't meed our
