Internet Connection Sharing with One Phone Line

 

by Bee Vang

 

The Internet, filled with information and entertainment has inspired more and more people to be connected online.  Many if not most families now have access to the Internet.  With Internet Connection Sharing, more people now can connect to the Internet individually or at the same time, and with only one phone line. All that you need is a computer that will act as the Internet Connection Sharing computer (connection host) and your other computers on the network.  The Internet Connection Sharing intercepts packets and passes them between the Internet and the network computers.  With this service, the IP address is automatically assigned and configured to each of the computers on the network. As you connect to the Internet via an ISP, your computer is assigned a unique IP address, which it uses to send and receive messages to and from the Internet. Each computer sends packets to the Internet. It identifies itself as the sender using both its IP address and a subaddress.

 

To start up your connection you will need a network connection device for every network computer (your phone-line), a modem, and the required software and services.  For the phone-line network, you will use your existing telephone wiring.  This is probably the one of the least expensive connection device for a network.  It is also easy to install and cables are not required.  All you need to have is a phone jack for each computer network. 

 

For the modem, you will need a modem for your connection host computer.  This is your network’s connection host to the Internet.  All computers on your network will use this computer to connect to the Internet.  There are different kinds of modems you can use such as a standard data/fax mode (such as a 56K modem), an ISDN (Integrated Services Digital Network) modem, an ADSL (Asymmetric Digital Subscriber Line) modem, or a cable modem.  Here are the advantages and disadvantages about each of the modems.

 

Standard data/fax – connects to a standard analog telephone line with a maximum

        speed of 56 Kbps.  It is inexpensive and pre-installed.  It has

        the slowest connection speed.

            ISDN                       connects to ISDN digital telephone service with a maximum

        speed of 128 Kbps.  Much faster that the standard modem and

        has a dedicated line. It requires digital telephone service and

        line fees.

            ADSL                      connects to a ADSL line with a maximum speed of 1.5 Mbps. 

        The fastest connection from a home and is dedicated.  It

        requires special connection not offered in many areas, and is

        more expensive than standard phone line fees.

Cable                      connects to TV cable line.  It has high-access speed using cable

       lines in homes.  Requires cable modem service not available in

       all areas.

 

You will need one ISP account for Internet Connection Sharing.  All computers will connect to the ISP account through the network connection host.  When a network computer try to connect to the Internet, the host will start connection to the ISP.  TCP/IP drivers are needed for every computer on the network.  For Windows 95, an installation disk is required for the installation.  All PCs with Windows 98 already have TCP/IP pre-installed.

 

After setting up the network and verifying that your network is working, you are ready to install the Internet Connection Sharing Service.  Remember that when the service is installed, the IP addresses automatically assign a unique address to each home network computer as it boots up.  It will also set up the connection host for name resolution and access to the Internet.  Remember that you only need to install the service to only one computer on the network.  This computer will be the connection host; therefore, you should choose the one with the fastest modem.

 

To install the Internet Connection Sharing:

 

Click

·        Start button and point at Settings

·        Control Panel

·        Add/Remove Programs

·        Windows Setup tab

                        Select the Internet connection Sharing check box from the Component box

                        Click OK. After installation, the Internet Connection Sharing dialog box

            appears

·        Select the adapter you want to use in the Connect To The Internet Using box Enable Dial On Demand checkbox and select the Internet service provider Dial Using box to auto dial your ISP.

·        In the Share This Home Network box, select the network adapter you are using.

·        Click Enable DHCP On My Home Network to dynamically assign private IP addresses to the other computers on the network.

·        After the installation, select the Internet connection, set up dialing options, select the home network adapter, enable automatic IP addressing for the network computers.

 

The final step for this Internet Connection Sharing is making sure that the network computers will not dial up using their modem for connection.  They should all be accessing the Internet through the network LAN.
