Wired Network “unmanaged” in Network Manager

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

      leafpad /etc/NetworkManager/NetworkManager.conf and then edit

          ...

          [ifupdown]

          managed=true

          ...

• Save the file. Inorder, to make the changes to come to an effect, type

      /etc/init.d/network-manager force-reload
