Connect Via Ethernet

Windows XP is probably the easiest version of Windows to configure. For the Ethernet configuration, you need to know the IP address of your computer.

Find your IP Address

1. From the Start menu, choose Control Panel.
   Result: The Control Panel window appears.
   
   
2.  If the Control Panels are set to Category View (about 9 icons listed), click the option in the upper left corner of the window labeled Switch to Classic View.
   Result: The Control Panel appears in "classic" view, that is, the way it looked in earlier Windows operating systems.
   
   
3. Double-click the Network Connections icon.
   Result: The Network Connections window appears. As in the illustration below, you may see other connection icons or you may not. Don't worry either way.
   
   
4.  Right-click on the Local Area Connection icon and click Properties. (Note: Local Area Connections is the default name. You can change the name by right-clicking and selecting Rename.)
   Result: The Local Area Connection Properties window appears.
   
   

Configure TCP/IP

1. Select Internet Protocol (TCP/IP) and click the Properties button.
   Result: The Internet Protocol (TCP/IP) Properties window opens.
   
   
2.  Click on the Use the following IP address: radio button.
   Result: This activates the fields in the rest of the window and allows you to enter the necessary addresses.
3.  Complete the configuration fields as in the table below.
   
   This part of the configuration requires attention to detail, because one typo will prevent you from getting on the network. Be sure you have this information at hand when you start to configure the TCP/IP protocol:
   
   

   Field	Required Setting
   IP Address	18 .x.y.z (where x,y, and z are numbers)
   Subnet mask	255.255.0.0
   Default gateway:	18. x.0.1 (Where x matches the x in your IP address)
   DNS (Domain Name Servers)	18.71.0.151 18.70.0.160 18.72.0.3

   
   
   Enter these numbers in the appropriate fields and click OK.
4.  Continue to click OK or Close as appropriate until you return to the Network Connections screen. The Local Area Connection icon text should now say Enabled.

Test Your TCP/IP Settings

Launch your web browser. If you have completed the configuration successfully, the browser opens at your designated home page. If you have not completed the configuration, you will receive an error message that says that your browser was unable to connect properly. Go back and check your settings.

 

Connect Via Wireless

Once you have configured your computer for Ethernet connectivity, you can register for one of the mobile computer services that let you connect your laptop computer from many sites on campus either via a DHCP (Dynamic Host Configuration Protocol) or wireless.

To use this service, if you are not a student, you must have a valid static MITnet IP address which you do if you have just completed the Ethernet connectivity setup.

You will need the following

• An MIT ID card 
• A Kerberos username and password
• MITnet web certificates

 

Connect Via Tether

   You are now connected to Tether. If you have any problems, check your configuration and make sure the phone line is plugged into the modem. If you still cannot make a connection, call the Service Desk at 253-1102 during working hours (Monday through Friday, 8am to 6pm).

 

Connect Via iPass

What is iPass?
iPass is a fee-based remote connection service for members of the MIT community who are traveling outside the Cambridge/Boston area and need to connect to the Internet and to MITnet.

With the iPassConnect client installed on your computer, a modem, and an MIT iPass account you can be just about anywhere in the world and connect to the Internet by dialing a local (or nearby) telephone number, saving long-distance toll charges (for example, compared to Tether or with an MIT calling card). In addition to standard modem dialup, high-speed wireless and wired broadband iPass connections are available at some airports, hotels, and conference centers worldwide. iPass operates by consolidating Internet service providers into a single global virtual network.

Connecting
Registration and use of iPass requires that you have a Kerberos username and password. Currently, iPass is available only to members of the MIT community whose usage fees can be charged to an Institute cost center. In the future, iPass will be available for personal use to MIT faculty, staff, and students, with billing through payroll deduction or student accounts.

Note: iPass is not intended to replace a dialup connection from your home that you use for more than four hours a month.

For more details, see iPass at MIT.
