question #2: ubuntu documentation Wrong.

    the information posted on:
   Official Documentation Ubuntu Documentation > Ubuntu 10.04 > Internet and Networks > Modems > Connecting with a modem
Connecting with a modem

IS WRONG.

NetworkManager doesn't currently support modem connections, so you will need to install the gnome-network-admin package. If you have no working Internet connection, then you will need to obtain this package and install it, see Downloading and installing a .deb package for more information.
-----STEP DONE----

You will need to know the following information:

ISP Phone Number; Username; Password; Domain Name Server (DNS) addresses.
 ----GOT IT------

1.Open System → Administration → Network

2.Press Unlock and type your password to unlock the settings

-----DONE----

3.Select the Connections tab. THERE IS ZERO CONNECTION TAB. TABS ARE 3.

4.Select Point to point connection and press Properties.
                                         NO SUCH ANIMAL RESIDES IN SYSTEM:ADMINISTRATION:NETWORK

Is this some kind of joke?
