Issue:
- WLAN works fine with NetworkManager
- Wired Device (ethX) is marked as “unmanaged” and doesn’t work even if it gets DHCP-lease/IP-address
- /etc/network/interfaces looks correct
Solution:
- Open root terminal and type
...
[ifupdown]
managed=true
...
- Save the file. Inorder, to make the changes to come to an effect, type
/etc/init.d/network-manager force-reload
