Comment 9 for bug 92085

Removed and reloaded network-manager (hence ubuntu-desktop). I now find that following a hard reboot, the network manager shows no network connection. However, if I click the NM icon and click 'Wired Network' the NM finds the card & network works properly.

There are no wireless devices on this machine & IP is set for a static address. /etc/network/interfaces is set as:

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static
address 192.168.4.101
netmask 255.255.255.0
gateway 192.168.4.1

Seems that NM should default to /etc/network/interfaces settings.
