Letzten Freitag habe ich auf Ubuntu 15.10 aktualisiert. In diesem Moment war ich mit Wifi mit einem Unternehmensnetzwerk verbunden. Nach dem Upgrade funktioniert es nicht mehr.
Konfiguration für die WLAN-Verbindung:
Sicherheit: WPA & WPA2 Enterprise-
Authentifizierung: Geschütztes EAP (PEAP)
Kontrollkästchen Kein CA-Zertifikat erforderlich.
PEAP-Version. Ich habe alle 3 Optionen ausprobiert: Auto, Version 0 und Version 1.
Innere Authentifizierung: MSCHAPv2
Benutzername und Passwort werden gespeichert. Ich kann weiterhin mit meinem Telefon mit denselben Anmeldeinformationen eine Verbindung zum WLAN herstellen.
Folgendes sehe ich im Syslog:

Was kann ich tun, um wieder eine Verbindung herstellen zu können?
Das Problem ist, dass einige Router und / oder Access Points WPA2 Enterprise mit schwachem DH-Schlüssel verwenden und Network Manager 2.4 keine Verbindung zu diesen Netzwerken herstellt.
Normalerweise tritt dieses Problem unter Ubuntu> = 15.10 auf. Derzeit besteht eine vorübergehende Problemumgehung darin, wpa_supplicant mit den folgenden Anweisungen auf 2.1 (von Ubuntu 15.04) herunterzustufen:
