           EXERCISE 3 : LAN and WAN setup



            Objectives

           At the end of this exercise you shall be able to
           •  create a LAN and check connectivity by between two computer
           •  share a file, folder and a printer over a network
           •  configure a router and set up a WAN.

           Requirements

           Tools/Materials
           •  2 or more PC/Laptop connected to a network
           •  Printer
           •  Router

           Procedure

           Connecting two computers using LAN
           TASK 1: Creating a LAN
           1  Determine whether or not your computers have Ethernet ports.
           2  Check to see if you have a crossover Ethernet cable.

           3  Plug one end of the Ethernet cable in to one computer.
           4  Plug the other end of the Ethernet cable in to the other computer.
           5  Finish.


           TASK 2: Checking the IP address of a given computer
           1  Open the command prompt. press windows + R and type cmd into the field. Press Enter to open the command
              prompt.

           2  Type IP config and press Enter. This will display a list of your network connection information. All of the network
              connections on your computer will be displayed.
           3  Find your IP address your active connection may be labelled wireless network connection, Ethernet adapter, or
              Local Area Connection. It may also be labelled by the manufacturer of your network adapter. Find your active
              connection and look for ipv4 address.
              •  The IP address is four sets of digits, with up tc three digits per set. For example, it might look like 192.168.1.

           4  Finish.

           TASK 3:  Check connectivity between two computers

           1  Open the command prompt. Press windows + R and type cmd into the field. Press Enter to open the command
              prompt.
           2  Type the word “ping” Followed by a space and then your IP address at the DOS prompt (e.g.ping 111.22.33.4).
              Press the “Enter” key once.
           3  View the result of the ping. If a result of “request timed out” appears, then there is a problem with either
              the computer or the network. A successful ping will result in a response of “Replay from” followed by the IP
              address.
           4  Repeat the above steps in the other computer

           5  Finish.
