}

note: credentials have been was by local hotel management staff as:
Wi-Fi: Naturhotel Wieserhof
Password: N@tur%Wieser
i.e. the credentials are correct and the SSID was visible with ifconfig wlan0 list scan
 

WPA started as:

# /usr/sbin/wpa_supplicant -d -i wlan0 -c /etc/wpa_supplicant.conf -D bsd

connection (associating, IP by DHCP) was only sometimes possible far away from the AP (in the hotel room, where the staff said it is not supposed to work), and was never possible near the AP (in the lobby, where it was supposed to work);

I tested the various combinations, the best was what is visible above as aktive lines;

I will attach log files;
