Subject:   How to connect to a Wifi AP w/o much information from its provider

Hello,

The school of my son offers Wifi to the pupil. The SSID is "Schueler"
and each of the kids has a login and password assigned from the school. Not more
information. An iPhone connects out of the box by just asking for the
two values (login/password). With our wpa_supplicant I couldn't get how to
set accepted values.

I have here what the ifconfig command on my laptops says about the AP values:


# ifconfig -v wlan0 list ap | egrep 'SSID/MESH|Schueler'

Has someone an idea how to make a wpa_supplicant.conf entry for this
SSID?

Thanks
