http://askubuntu.com – 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: ifup wlan0, then I have network access. My /etc/network/interfaces looks like this: # 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 sys (HowTos)
