Dukeblue: Getting connected on iPhone or iPad (iOS devices)

 Duke University has implemented a secure wireless network known as Dukeblue which uses the authentication mechanism WPA-2 Enterprise and 802.1X. When correctly installed and configured, this network can protect your Duke NetID and password, and ensure your data and transactions are secure and protected.

In order to connect to the secure network, adjustments will need to be made to your device settings. Follow these steps to configure your Dukeblue connection for your iPhone or iPad so you can take advantage of this layer of security. The information from this article was created and tested on a device running iOS version 8.3 and was verified up to iOS 9.0.2. 


  1. Connect to the DukeOpen wireless network.
  2. Open up your Safari Browser
  3. Go to https://launch.dukeblue.duke.edu and click the JOIN Secure Wireless Network link.
  4. The web page will display information about your device operating system. If this information is incorrect, select your device (iPhone/iPad) from the pop-up menu at the bottom of the page.

  5. Enter your Duke NetID and password in the fields provided, then tap the JoinNow button.

  6. An informational page will appear indicating that it may be necessary to select the Dukeblue network from your wireless networks list.
  7. A new screen will appear with the heading Install Profile. Tap the Install link in the top right of the screen. 

  8. Enter your phone passcode. NOTE: fingerprint identification will not work here.
  9. A new screen will appear with a warning message regarding the installation of this certificate. Tap the Install link in the top right of the screen to continue. When prompted, tap Install again. Please note that you may see a message that the certificate is not signed but the certificate is valid. Please disregard this message in this instance. 

  10. The certificate will be installed. Tap Done to complete the profile installation. 

  11. If you have configured iCloud Keychain or your device, you may see an option to save the login and password you provided for autofill purposes. It is not necessary to save this password to connect to Dukeblue. We recommend not saving this information to your iCloud Keychain. 

By default, the Dukeblue network should be active. However, you may want to verify this by doing the following:

  1. Go to Settings. If you see the Configuration Profile settings, tap General in the top left corner and then tap Settings to return to the main screen.
  2. Verify that Dukeblue is the current Wi-Fi network active on your device. If it is not, tap Wi-Fi and in the networks that appear, select Dukeblue

NOTE: You should routinely verify that your wireless connection has joined Dukeblue. In any given location, a large number of networks are available and your computer may not default to Dukeblue. If you are not connected to Dukeblue, you will not be able to advantage of the enhanced security this network provides. 


Setting your preferred network 

 It is not possible to rank preferred wifi networks on your phone. You can "forget" networks that you've previously joined or disable the option "Ask to Join Networks".  Apple does provide documentation on the logic that an iOS device follows to determine what network to join here

Manually connecting to Dukeblue

It is recommended to use the installer to connect to Dukeblue but it is not mandatory. You can join it as you would other WiFi networks.

  1. Go to Settings -> WiFi.
  2. Select Dukeblue from the list of networks.
  3. When prompted, provide your Duke NetID and password and click Ok.
  4. You should now be connected to the Dukeblue network.
