The following problem happened after upgrading from 11.10 to 12.04: network manager applet in Unity-2D does not show properly network connections, but indeed networking is working properly.
It happens only after a boot, not during session logout/login, the first 4 screenshot were taken as follows:
- login (1): notice connection information window, the wired connection is working properly.
- disabled (2)/enabled (3) networking brings contents of network manager applet in the correct state/appearance (4).
Also via 'System Settings -> Hardware -> Network' I tried to toggle 'Airplane mode', which I don't know why it is always switched on (maybe cause wireless adapter is hardware switched off), wich led to nothing.
Other workaround methods are:
- unplugging and plugging back Ethernet cable, or plugging it after login.
- enabling/disabling wireless adapter.
