Hallo,
ich möchte bei meinem t450s eine Verbindung mit dem O2 Netzwerk (postpaid) aufbauen. Die Verbindung hatte ich im Netzwerkmanager konfiguriert. Wenn ich diese nun auswähle deaktiviert sich das Gerät (cdc-wdm0) und ist auch nicht mehr auffindbar. Erst nach einem Neustart taucht das Gerät wieder auf.

Nützliche Daten:

Ich hatte das Gerät mittels
Code: 
 mbimcli -p -d /dev/cdc-wdm0 --intel-modem-reboot
neugestartet, daher die Gerätenummer 6. Das neustarten ist nur möglich, wenn ich noch keinen Verbindung mit cdc-wdm0 aufgebaut hatte. Sobald ich versuche eine Verbindungs aufzubauen ist das Device nach 5 sekunden nicht mehr auffindbar.

Hat jemand einen einen Ansatz, was ich probieren könnte oder falsch mache
