Campus Network Quick Start Guide

To connect your computer to our campus wired network, you'll need:


  1. a network cable (CAT 5 or better straight cable, RJ-45 terminated at both ends)
  2. a laptop or desktop PC with network card (100baseT FastEthernet or 10BaseT Ethernet card)

Next setup your computer as follows:

  1. Network card and drivers first properly installed
  2. Configure your computer to use Obtain an IP Address Automatically or DHCP-enabled. This is usually already enabled by default in most network card installation.

  3. Next plug the network cable to the network point (i.e. the network access wall-outlet) at one end and the other to your computer. Check that your network card link indicator lit up.
  4. On Tools->Internet Option->Connection->LAN Setting, please leave all Automatic Configuration and proxy options unchecked.
  5. If all don't work well, first check the network cable connection and network card link indicator. Next verify that your computer has been assigned an IP address by:
    -In Windows NT/2000/XP: at Start>Accessories>Command Prompt type ipconfig
    -In Windows 95/98/ME: at Start>Run type winipcfg
    -For LINUX, UNIX machine: at the system prompt type ifconfig

    You should be able to see the TCP/IP configurations of your computer as shown:

    IP Address155.69.x.x or 172.x.x.x
    Subnet Mask255.255.x.x
    Default Gateway155.69.x.x or 172.x.x.x
  6. You can try using the ping command by typing the IP loopback address of at the command prompt i.e. : ping

    You should be able to see reply messages as shown:

    Pinging with 32 bytes of data:

    Reply from bytes=32 time<10ms TTL=128
    Reply from bytes=32 time<10ms TTL=128
    Reply from bytes=32 time<10ms TTL=128
    Reply from bytes=32 time<10ms TTL=128

    Ping statistics for
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
    Approximate round trip times in milli-seconds:
    Minimum = 0ms, Maximum = 0ms, Average = 0ms

    Successful use of ping indicates that the IP configuration of your system is probably functional. If you still can't connect to the Internet, click here to find where you can get help.
