Hallo Linux-Netzwerkspezialisten:
Ich habe folgendes enervierende Problem auf meinem Laptop opensuse 11.2 i586, KDE 4.3.5, Netzwerkkonfiguration mit knetworkmanager (wlan), 2.6.31.14-0.1-desktop, UMTS-Surfsticks ZTE110 bzw. Huawei 160E, Provider Vodafone.
Nach einigen Mühen und Anpassungen (usb_modeswitch, udev-Regel für ZTE110 usw.) funktioniert die Geräteerkennung als Modem bei beiden Sticks fehlerfrei.
Unabhängig, mit welchem Stick und mit welcher Software ich mich nun mit dem Internet verbinden will, kommt es zum Einfrieren der KDE-Plasmaoberfläche nach wenigen Sekunden, sobald die Verbindung (hier 1&1) steht. Das gilt für wvdial, umtsmon oder die spezielle Vodafone-Linux-Software gleichermaßen. Wenn ich den Stick ziehe, läuft wieder alles normal.
Hier ein Auszug von wvdial 1und1
Cat /var/log/messages liefert ähnliches:
Route -n liefert
Leider verstehe ich von den Netzwerkzusammenhängen zu wenig, um das alles einordnen zu können. Aber ich bin sicher, hier ist irgendwo ein kapitaler Bock versteckt, und jemand von Euch kan mir auf die Sprünge helfen.
Bin für jeden Tipp dankbar.
Gruß Z.
P.S. Schreibe die Zeilen übrigens von einem Virtualbox-Win XP aus, wo der Stick läuft.

Die Verbindung wird also zunächst normal hergestellt, dann kommt nach einiger Zeit eine Nameserver-Fehlermeldung.wvdial 1und1
