Dukeblue – Frequently Asked Questions

Below are answers to frequently asked questions about Dukeblue – Duke’s secure wireless network service. If you have additional questions, contact the OIT Service Desk at (919) 684-2200.

 

 

What is Dukeblue?
Dukeblue is Duke University’s secure (encrypted) wireless network. Dukeblue uses your NetID and password to authenticate your connection. The secure network encrypts your traffic while it traverses the wireless network – once on Duke’s wired network it is no longer encrypted and flows in the same way as any wired connection on Duke’s campus network.

What are the benefits of using the Dukeblue secure wireless network?
The Dukeblue secure wireless network provides all the benefits of the regular wireless service – anytime, anywhere access to the Internet. Dukeblue is available to students, faculty and staff, as well as affiliate users. Secure wireless is preferable to the regular wireless service, it provides a higher level of security without affecting device performance.

Why does my data need to be secure?
Without encryption hackers or nefarious persons may intercept your data – including email, passwords, web traffic, and other personal or Duke data.

Why should I use the installer versus selecting Dukeblue from the list of available networks?
Most wireless clients don’t know, out of the box, how to distinguish between certificates they should trust and those they shouldn’t. The clients rely either on pre-loading of trusted certificates or asking your permission in order to decide what to trust and what not to trust.

Pre-loading your client with the real certificates for the Duke RADIUS servers, either by using the installer or manually configuring your client with the proper certificates, makes it less likely that you will fall victim to hackers or nefarious persons trying to intercept your data – including email, passwords, web traffic, and other personal or Duke data.

What is SecureW2 JoinNow App?
SecureW2’s JoinNow App is the automatic installer which configures and connects your devices to Duke’s secure wireless network.

After configuration, do I still need the SecureW2 app?
No. After configuring your device and connecting for the first time you can delete the SecureW2 app.

Do I need to use the Automatic Installer?
No. You can manually configure your network settings to connect to the secure wireless network. However, the automatic installer will eliminate common configuration issues when initially setting up your device to connect to a secure network. Please note that the installer does not work on Android or Windows 7. You will need to manually set up Dukeblue on devices running Android or Windows 7.

How do I make Dukeblue my default wireless connection if it is available?
You can make Dukeblue your preferred network. See the installation instructions for details.

How is the security different between the Duke and Dukeblue wireless networks?
The Dukeblue secure wireless network is a WPA2-Enterprise encrypted network which provides 128-bit encryption. The “Duke”and “Duke Visitor” wireless networks are not encrypted; your data and personal information are not secure. The secure network encrypts your traffic while it traverses the wireless network – once on Duke’s wired network it is no longer encrypted and flows in the same way as any wired connection on Duke’s campus network.

What is 128-bit encryption?
128-bit encryption is a data/file encryption technique that uses a 128-bit key to encrypt and decrypt data or files. It is one of the most secure encryption methods used. 128-bit encryption is considered to be logically unbreakable.

Can I connect my wireless printer, gaming console, or smart TV to Dukeblue?
Miscellaneous devices including printers, gaming consoles, smart TVs, and other multimedia equipment are not supported by the secure wireless network. You will need to register and connect your device to the DukeOpen wireless network. Click here for information on registering and connecting these devices to the Duke wireless network.

What if I am having wireless problems after installing the Windows 10 Creator update?
This is a known issue with the Windows 10 Creator update. To correct this issue, go to https://launch.dukeblue.duke.edu and install the Dukeblue profile. Once that is complete, update your wireless driver. You can do this by downloading the latest wireless driver for your device (e.g., for Intel chips, go to http://www.intel.com and download the Intel® Driver Update Utility) and installing it. Be sure that when you install the driver, you are pointing at the ini file and not installing additional software. (for more details, see KB Article, How to install a wireless driver for Dukeblue.) If you are still having issues after those two steps, disable Receive Segment Coalescing (RSC) (see KB0027174). If you continue to have issues, please call the Service Desk at 919 684 2200 or go by The Link in Perkins library.

What do I do if I am experiencing connectivity problems?
If you are experiencing connectivity problems please contact your local IT support group or the OIT Service Desk.
