Title:
network-manager loses wired interfaces
Status in “network-manager” package in Ubuntu:
New
Bug description:
For some reason, sometimes network-manager seems to forget I've one of
the wired interfaces. The computer would start-up right, it connects
to my ISP and sometimes a po-up would show saying that I've been
disconnected. If I want to reconnect I can't because the connection
does not show up any more. If I do a "sudo service network-manager
restart" the conenction will come up again and it will show in the
indicator. I've no idea what causes this. a dmesg does not show
anything wrong but there is some info in syslog.
