2 Internet Connectivity Assumptions These instructions assume the following points are true: 0. You are using a PC with Microsoft Windows 98 or higher or a Macintosh with OS 9.x or higher. 0. You have a properly installed Ethernet Network Interface Adapter (NIC) in your computer. 0. You have a CAT5 Ethernet Network cable with RJ 45 connectors on each end. Identifying the Network Jack The pictures that follow represent some of the typical network jack configurations that are present in our residence halls. Some rooms will have a wall jack like the one shown below with ONLY an outlet for Internet access. The wall jacks providing Internet access will be indicated by labels with a bluish gray color picture of a computer monitor. 2

3 The other rooms will have a wall jack configuration like the two pictures shown below. In this instance, the outlet on the left indicated by the red label and a picture of a telephone is for telephone access ONLY and cannot be used for Internet access. The outlet on the right indicated by the bluish gray label and a picture of a computer monitor is for Internet access. Note that these two ports are of different sizes. The telephone outlet uses an RJ 11 jack which is somewhat smaller than the RJ 45 jack on the right used for Internet access. 3

4 Identifying the Ethernet Cable An Ethernet cable for use on our network should be a CAT5 cable with RJ 45 connectors. The cable should look similar to the one pictured below: The following pictures demonstrate the differences between an Ethernet cable and a cable used for normal telephone communications. NOTE: The telephone cable has the smaller RJ 11 connectors as opposed to the larger RJ 45 connectors of the Ethernet cable. Notice their sizes compared to the dime. The cable on the left is for use with a telephone, and the cable on the right is used for connecting to the Internet. 4

5 Identifying the Network Interface Card Most new computers have the network interface card (NIC) port labeled with this symbol,. Depending on the age of your computer, you may or may not have this symbol. If you do not, the network interface card (NIC) port is still easily identified as it looks like an oversized telephone jack. A Network Interface Card (NIC) looks like the following picture when not installed in the computer: The pictures on the following page show the back of some computers with the Network Interface Card (NIC) pointed out with the tip of a pencil; identify this port on the back of your computer. NOTE: It will look like an oversized telephone jack. If you cannot find a similar jack on your computer, you might NOT have a Network Interface Card installed: 5

7 Connecting your Computer to the Network Jack 1. Plug the CAT5 Ethernet cable with into the Internet outlet on the wall jack. Remember to plug your cable into the outlet with the bluish gray label marked with the picture of the computer monitor. The outlet will look similar to the one below: 2. Plug the other end of your CAT5 Ethernet cable into the port of the previously identified Network Interface Card on the back of the computer. The outlet will look like the one on the card shown below. NOTE: This is what the NIC looks like when it is not installed in a computer. The port to connect to is the black square in the middle of the long silver rectangle. 7

8 3. The finished connection should look like the following: 8

9 Configuring Windows XP Home/Professional 1. Start Microsoft Windows as you normally would by pressing the power button on your computer system. Wait for Windows to start successfully. 2.

14 9. For security reasons, all computers and network devices must have bridging disabled. If your computer has bridging enabled, your network connection has probably already been automatically disabled. A bridging connection would look like this: 14

15 10. To disable this bridged connection, simply select it and choose Delete this connection from the Network Tasks menu on the left side of the window. 15

16 11. After the bridging connection has been deleted, your Local Area Connection that you are using to access the network will probably still not work. You will need to contact your RA or call the Information Technology Service Center at 651 HELP ( ) so that your network connection can be turned back on. Be sure that you have removed the Network Bridge before you call to have your connection turned back on. Configuring Windows 2000 Professional and Windows ME 1.
