Command line application for managing wireless and 3G connections


I am in the need of managing Wireless and 3G connections only by using commands on my Ubuntu minimal system, so I would like to know if is there some application or utility that already does that.

Specifically I need:

Regarding wireless connections:

1. Submit a command that outputs available connections or SSIDs.
2. Upon a given SIDD name, security type, encryption type and password, submit a "Connect" command that tries to establish a connection, and give a feedback of the operation result.
3. Submit a command that outputs the current status of the active wireless connection, if any.

Regarding 3G connections:

1. Given a dial number, APN, username and password, submit a "Connect" command that tries to establish a connection and give the feedback of the operation result.
2. Submit a command that outputs the current status of the active 3G connection, if any.

Of course, the start point for the two cases is that there is a properly configured wireless adapter and 3G modem, with an active SIM card.

The solution I'm searching for, is for my minimal Ubuntu 14.04. So I got no graphic interface, and all things have to be installed with apt-get.

Thanks for reading and your valuable help.

Network Manager provides CLI tools for servers without graphical environments. In particular, 'nmcli' can be used to control connections

List connections
nmcli c
Check status of active connection(s) eg
nmcli c status
HOME bd1a6207-2ee7-4b2f-b0f8-6d266c47a748 wlan0 yes no --
For more info, do
nmcli c status id HOME
Start my 3G connection
nmcli c up id "3G_TNZ"
Stop it with
nmcli c down id "3G_TNZ"
New connections can also be defined using
nmcli con edit....
For more info
man nmcli
There is also cnetworkmanager (a CLI client for NetworkManager) available if you prefer.
