Show all images | Hide all images

Requirements

In order to connect to the UIwpa2 wireless network with a Mac OS X computer, your system must:

• Have an AirPort Extreme wireless card (old AirPort cards from 2002 and earlier do not work)
• Support 802.11g and/or 802.11a in addition to 802.11b (the B-only cards do not work)

To check your system's compatibility, go to the Apple menu > About This Mac > More Info to open the System Profiler. Then, under the Network heading, look at your AirPort card information.

If your system doesn't meet the requirements for WPA2, you can continue to use UIUCnet Wireless instead.

Initial configuration

1. From the Apple menu bar, select the AirPort icon and make sure that the AirPort is turned on.

2. Select Open Network Preferences.

Network Preferences window

3. Click the Advanced button in the lower right section of the window.

4. In the AirPort window that appears, select the 802.1X tab and change the Domain to User.

Note:  If you are unable to change the domain, click Disable 802.1X Login.

5. In user domain view, click the + button below the Configurations pane on the left to create a new profile.

6. Label the profile UIwpa2.

7. Fill out the configuration as follows:

• User Name: Leave blank (you'll complete this information later)
  
• Password: Leave blank
• Wireless Network: UIwpa2

(It may take a minute or so for the list of available wireless networks to be provided.)

• Authentication: TTLS (uncheck all other protocol options)

AirPort configuration window

8. While TTLS is selected in the Authentication pane, click Configure.

9. Enter the following information:

• TTLS Inner Authentication: MSCHAPv2
• Outer Identity: (Leave this line blank.)

TTLS configuration window

10. Click OK in the TTLS window.

11. Click OK in the AirPort window. You should now see the Network window again.

Getting connected

1. Select UIwpa2 from the Network Name list in the Network window.

2. Click Apply.

3. You'll be prompted for your user name and password. Enter:

• User Name: Your NetID
  
• Password: Your Active Directory password

  (Not sure what your Active Directory password is? Try your Express Email or NetFiles password, or reset your AD password at the Password Home Page.)

4. Depending on whether you have used a trusted wireless network before, an 802.1X Authentication warning message may pop up at this point. The message explains that "the server certificate is not trusted because there are no explicit trust settings." Click the Show Certificate button.

5. In the Verify Certificate window:

• Select neauth1.cites.uiuc.edu
  (or neauth2.cites.uiuc.edu if that is the option presented)
• Check the check box that says Always trust 'neauth1.cites.uiuc.edu
  (or Always trust neauth2.cites.uiuc.edu).

6. Click Continue.

Note: Depending on your computer's settings, you may be prompted for your computer's administrator user name and password in order to make this change to your certificate trust settings.

Verify Certificate window

Note:   If your computer is unable to reconnect to UIwpa2 after it has been either restarted, put in sleep mode, or connected to another network, select the AirPort icon and turn the AirPort off and then on.

Trouble connecting?

If you have trouble getting connected to UIwpa2, or if your computer shows a connection but doesn't allow Internet access, remember: you can always use UIUCnet Wireless instead. Switch your selected network to UIUCnet and open a browser window to log in through QuickConnect, and you'll be ready to go.

Disconnecting when finished

To disconnect from the UIwpa2 network, you can either select a different wireless network available in the area or turn your AirPort wireless card off.
