Configuring Wireless on OS X 10.5 Apple Airport/Airport Extreme Card
for the Physics Wireless Network

Overview:

1. Fill out the IP Address Request Form for your wireless card.
   Special items to note on the form in the Comments section:
1. Specify that you are using a wireless card. Be sure you are providing the MAC address of the wireless card and not the ethernet interface. Here is information on how to find your MAC address.
2. Specify a username/password combination for use with wireless. If you are already using the Physics dial-up modems, you will use this username/password.
3. Specify the name of your machine if it has already been on the Physics network. If your machine has never been on the Physics network, we will need to scan your machine for security vulnerabilities behind our firewall in PCS. (HEP users can disregard this step, as you will be connected to the HEP network automatically based on your username and password.)
2. Setup TCP/IP for DHCP in the Airport settings.
3. Configure the OS X 802.1x client.

Client Configuration

1.      You will need administrative access to do this step. (The first account created will have administrator rights)

2.      From the desktop click on the Apple menu.

3.      Choose 'System Preferences...'

4.      Click on the 'Network' icon.

5.      If you are not logged in as a system administrator, click on the lock at the bottom left hand corner of the window, and login.

6.      Click on the "Location: " drop-down menu and select "Edit Locations..."

7.      Click on the “+” symbol to create a new location.

8.      Name the location "UCSB Physics Wireless", click “Done”

9.      Select "Airport" from the Network panel's list

10.  Click on the “Advanced” button.

11.  Under the TCP/IP Tab, Set "Configure IPv4:" to "Using DHCP", stay in the “Advanced” network window for the next step.

12.  In the “Advanced” network window, Click on the "802.1X” tab (you should still see “AirPort” as a panel title above the menu tabs).

13.  Under the 802.1X menu bar selection, click on the “+” symbol in the “User Profiles” panel (this will be blank if there are no users yet), click “Add User Profile”.

14.  Name the Profile, and fill in the User Name field with the one you provided to PCS.

15.  Put the password you gave to PCS in the Password field.

16.  Type "physics" into the Wireless Network box.

17.  Make sure that "TTLS" is the ONLY active authentication type.

18.  Select TTLS and click the "Configure..." button.

19.  Select "PAP" from the TTLS Inner Authentication pop-up window.

20.  Click OK, the TTLS config window closes.

21.  Click OK in the “Advanced” Airport configuration window to save the settings and close the window.

22.  Click “Apply” in the Network System Preferences window.

23.  Now in the Network Preference Pane, make sure that “Airport” is selected from the list in the network devices panel.

24.  Click "Turn Airport On”.

25.  A window opens saying that "Authentication failed because the server certificate" etc. Click "Continue” to close the window.

 (This first attempt at authentication may fail, if so, click the "Turn Airport Off" button in the Network Preference Pane,.This changes back to the "Turn Airport On" button; click it to try to reconnect.)

NOTE: If there is a connection problem, and you already have a wireless location or wireless user profile, you may have to uncheck the “Ask to join new networks” checkbox in the Airport section of the Network Preference Pane. You may also have to uncheck the “Remember any network this computer has joined” checkbox in the “Advanced” window for the Airport Network window.
