I have an external USB wifi device (Netgear WG111v3) which I configured based on this guide, http://ubuntuforums.org/showthread.php?t=732827 It works perfectly on Network Manager. However, it connects only after I login with my username and password.
I want the wireless network connection to connect at the time of boot itself. I know I need to configure the /etc/network/interfaces file. But I don't know the exact configuration to use to setup wireless. As the connection is a WPA2-PSK, do I need to use wpa_supplicant?? If so, what is the configuration I need to use for the wpa_supplicant.conf file??
I am using Ubuntu 9.04 desktop.
