Go to System>Preferences>Network Connections>Wireless>Add. Enter your network details, and tick the box that says 'Auto Connect'. Also, the driver works better if your computer logs into your user account from bootup (i.e no login screen, just loading straight into ubuntu - you can change this by going into System>Administration>Login Screen>Unlock and set it to 'Login As (your username) automatically. Untick 'allow..seconds for everyone else to login first'. Then reboot and see if the network connects from bootup.
