Now I have the following devices: - Device: usb0 [Auto usb0] ---------------------------------------------------- Type: Wired Driver: cdc_ncm State: connected Default: no HW Address: 02:80:37:EC:02:00 Capabilities: Carrier Detect: yes Wired Properties Carrier: on IPv4 Settings: Address: 10.33.145.106 Prefix: 29 (255.255.255.248) Gateway: 10.33.145.107 DNS: 10.39.148.253 DNS: 10.39.148.249 - Device: ttyACM0 -------------------------------------------------------------- Type: Mobile Broadband (GSM) Driver: cdc_acm State: disconnected Default: no Capabilities: With nm-applet I can do (dis)connect cycles for the 3G connection. But I need to do this on "Ethernet (Lenovo F5521gw)" -> "Auto usb0" while "Mobile Broadband" -> "3G-Mobil" does not work but is still shown in nm-applet. This will make our user getting confused and so this is not a valid workaround for our production. So can someone tell me what the main problem is in this case and what has to be done to fix it? -- HG _______________________________________________ networkmanager-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/networkmanager-list
