That is what I would expect. wpa_supplicant should handle the reauth, IIRC,=

I think I know what you want to do. If you get a disconnect just try<br>
to reconnect. This might not be correct, e.g. what if your credentials<br>
have changed and you try the old ones again and again. Some networks<br>
will then disable your account.<br>
<br>
The question is what happens if the reauth handled by wpa_supplicant<br>
goes wrong.<br>
<br>
Thanks,<br>
Daniel<br>
