I am running Ubuntu Server 12.04. I have a wireless USB card. When I begin the boot process I see:
Waiting for network configuration
It turns out that the network never comes up. But once I get to the command line, if I type:

# The loopback network interface auto lo iface lo inet loopback # The primary network interface auto wlan0 iface wlan0 inet dhcp wpa-ssid xxxxxxx wpa-psk xxxxxxxx
Looking in my network-interface-wlan0.log shows:
Failed to connect to wpa_supplicant - wpa_ctrl_open: Read-only file system Failed to bring up wlan0. Failed to connect to wpa_supplicant - wpa_ctrl_open: Read-only file system ifdown: interface wlan0 not configured

I did some poking around. Basically once I login I need to do a:
because I think that ip thinks that is is up, but in /var/run/network the only thing that is 'up' is ifup.lo. Then I do a
and then everything works.
