Wired Laptop Internet Access 

The Rivera and Science Libraries have Dynamic Host Configuration Protocol (DHCP) ports for accessing the Internet from laptops.   This technology is somewhat dated however, there are still a number of users who do not have a wireless network card on their personal laptops and rely on the Library Link ports to connect to the library/campus network.

Note: A limited number of users can be connected via DHCP at once. There are 25 total ports.

How many in Science Library? and Where are they located?
9 = First Floor (Round Carrel of 8 located on North East Wall)
4 = Second (Right alcove located at north wing.)
4 = Third (Right alcove located at north wing.)
Total = 17

How many in Rivera Library? and Where are they located?
4 = Second Floor (West wall located a little North of the elevators)
4 = Third Floor (West wall located a little North of the elevators)
Total = 8 
 
0 in the Music and Media Libraries.

 The Library Link network ports in the study carrels are painted RED and only the port on the left-side is active.  None of the other network ports in the Libraries can be used with this service.

CONFIGURING YOUR WINDOWS COMPUTER TO USE DHCP
WARNING: If your laptop is already manually configured with an IP address for use in another location, these steps will erase that configuration. Remember to write down your existing IP address, Gateway address, Subnet mask, etc. before proceeding.
HINT: Your laptop may already be configured to handle DHCP. To check, simply launch your browser and see if you are live. Before configuring DHCP you must determine whether or not your system has the TCP/IP network software installed. You can check for that software by using the following steps.

1. Double-click the My Computer icon
2. In My Computer, double-click the Control Panel icon.
3. In the Control Panel, double-click the Network icon.
4. In the Network control panel, click on TCP/IP and
   then click on Properties button.
5. Listed under the Configuration tab there should be Client for Microsoft Networks and TCP/IP.
6. If you do not have Client for Microsoft Networks and TCP/IP listed, then you must install them from the system software CD that came with your machine. These features may be added to Windows 95/98 using the following instructions:
   1. Place the Windows 95/98 CD in the CD-ROM drive of your machine.
   2. While in the Configuration tab (in the Network Control Panel), click the Add button.
   3. The Select Network Component Type window will appear.
   4. Double click on Protocols - it should be listed in the box on the left side of the window. The next window that appears will give a list of manufacturers.
   5. In the Manufacturers box, select Microsoft
   6. Under Microsoft, select TCP/IP and click the OK button.
   7. Now back at the Select Network Component Type window, double click on Client.
   8. In the Manufacturers box that appears, select Microsoft
   9. Under Microsoft, select Client for Microsoft Networks and click the OK button.
   10. You will have to restart your machine after any installation or change to the networking area.

Once this is taken care of, proceed to the next step according to your operating system.
