I'm using network-manager on ubuntu oneiric. Every time the modem gets
disconnected (either by the network, or due to bad reception) it disappears from the network device list.

Is there no way to tell network-manager to manage a particular device again while keeping nm (and mm) running? btw, is there a utility which allows to show all devices managed by network manager, and their state (over dbus)? thanks, Eduard PS: when will this severe defect be fixed? Or is this bug ubuntu specific? _______________________________________________ networkmanager-list mailing list networkmanager-list@... http://mail.gnome.org/mailman/listinfo/networkmanager-list |

In the worst case, the modem disappeared after only four connection minutes > Is there a way to get it back without a reboot? I would prefer to know how to avoid that the device disappears from the NM device list. Can somebody please help us with this? Thanks in advance.

Does the device actually disappear from the USB bus (ie, it crashes)? When this happens check with lsusb to see if it's still there or not. If it is still there, we'll need some more detailed logs from ModemManager. I did notice that disconnecting the device failed, so it would be good to figure out why that happened. ie this line specifically from the logs: Dec 29 18:17:28 eeepc modem-manager[519]: <info> Modem /org/freedesktop/ModemManager/Modems/0: state changed (disconnecting -> connected) indicates that MM was not able to tell the modem to terminate the packet connection successfully, and thus it has no choice but to assume you're still connected. A detailed MM debug log would indicate which command is failing there. See: http://live.gnome.org/NetworkManager/Debugging for how to get that log. > btw, is there a utility which allows to show all devices managed by > network manager, and their state (over dbus)? nm-tool or "nmcli dev" Dan _______________________________________________ networkmanager-list mailing list networkmanager-list@... http://mail.gnome.org/mailman/listinfo/networkmanager-list |

Hi,
sorry for interfering in this discussion, but as I'm having the same problem than Eduard, I would like to provide some info about the issue. But before this, a probably important point: I have here a proprietary ModemManager (see [1]) but this doesn't matter as the failure seems to be the same: after an unexpected PPP-disconnection, the modem disappears from the NM devices list even the ModemManager didn't emitted the 'DeviceRemoved' signal. For reproducing the issue you can try killing the ppp-daemon when a PDP-context is up. Here this leads to the described issue: The modem is gone from the NM devices list even 'lsusb' shows that the modem is still there and the ModemManager too.
