Seit zwei Tagen kann ich mich nicht mehr mit dem Netzwerk unserer Schule verbinden. Während ich keine Probleme mit meinem iPhone habe und auch Kollegen nicht über Schwierigkeiten berichten, will mein Debian Buster (installiert auf einem Thinkpad X220) partout keine Verbindung aufbauen. An einem falschen WLAN Passwort liegt es nicht. Mit dem selben Gerät kann ich mich z.B. zu Hause problemlos connecten.
Ich habe mir die Syslog angesehen, habe aber zu wenig Erfahrung in diesem Bereich um etwas zu finden. Ist einer der Forummitglieder dazu in der Lage?
