Wireless@CBS

In early 2013, the Business School introduced new secured and guest wireless services throughout Uris Hall, Warren Hall and the Watson Library to replace it's legacy wireless service "WoFi".

The WoFi wireless service will be decommissioned on March 31, 2013.

The new wireless services (CBS-Secure and CBS-Guest) offer the following enhancements:

  • Multiple devices with simultaneous logins for individual users are now supported. Users can now access the wireless network with multiple devices (such as your laptop, iPad, and iPhone) simultaneously.
  • A more stable and reliable platform.
  • Enhanced login features. The new service uses Active Directory authentication and should log you in within a few seconds of entering your Lifetime ID (or UNI for faculty/staff) and password. Once logged in, the system will recognize your device throughout Business School buildings eliminating the need to log in again after some inactivity.
Note: You may need to log in again if, for example, you upgrade your operating system or we perform a major back-end upgrade.
  • A separate and open network(CBS-Guest) for guests and visitors. Guests visiting CBS can now access the visitor network without requiring credentials in advance of a School visit. This guest network is throttled, so that if a large number of visitors are on the network, bandwidth will not be lowered for CBS students, faculty, and staff utilizing the CBS-Secure service. Guests may also have multiple devices connected simultaneously to the network.

NOTE: At the present time we will not be making the guest network available in the Watson Library, the area of highest concentrated use for our graduate students. Guests in the Watson Library may still use the regular open Columbia University wireless network.

  • Unlike WoFi, all traffic on CBS-Secure is fully encrypted, enhancing security.
  • CBS-Secure allows comprehensive access to Business School resources including printing, the Research Grid, Exchange email and MS Lync.

How to Use CBS-Secure for CBS Students, Faculty, and Staff

To access CBS-Secure, follow these steps:

  1. (One-time task)  For returning faculty, staff, and students that have used WoFi on your device(s) in the past, we suggest you first remove (delete) WoFi as a preferred network on your device. This will prevent your device from automatically connecting to the old network.
  2. Select CBS-Secure as your wireless network.
  3. Log in with your Lifetime ID (or UNI for faculty/staff) and password.
  4. Repeat for each device you wish to connect.

How to Use CBS-Guest for visitors:

  1. Select CBS-Guest as your wireless network
  2. Open your internet browser (Firefox, Internet Explorer, etc...) and accept the User Agreement Policy.
  3. Repeat steps for each device you wish to connect.

Troubleshooting

If you are connected to CBS-Guest and cannot access your Outlook, verify that you have connected to the CBS-Guest network AND make certain you open your browser to accept the User Agreement Policy. Once this step is accomplished, you should be connected.  To verify that you are on the CBS-Guest network, your IP address should be 172.25.x.x.

A small number of people may need to change an extra couple of settings for CBS-Secure. The scenarios are as follows:
  1. If you use a highly secured corporate laptop on campus, you may need to manually configure your laptop to connect to CBS-Secure. Please use this guide for instructions on how to manually configure your laptop's connection through the Windows wireless manager:

    2. Manual Configuration of Windows for CBS-Secure

    If your computer uses a 3rd-party wireless manager, your company's IT support staff will be able to set up a profile on that application, with the information provided in this guide. To verify that you are on the CBS-Secure network, your IP address should be 172.30.x.x.

  2. If you are using Windows as a virtual machine (VM) within a Mac, you may need to do the following in order to print from CBS-Secure:

  3. If you have problems printing in Watson Library, you may need to manually remove the WoFi network settings by doing the following:
a) Press CTRL+SHIFT+ESC to open the Windows Task Manager. From File, select New Task (Run...)
b) Type "ncpa.cpl" and click OK to open the “Network Connections” control panel
c) Right-click on your “Wireless Network Connection” and select Properties

e) Click on Advanced…, then on the WINS tab
f) Remove any of the following WINS addresses if installed, by selecting the address and clicking Remove
a. 10.100.10.5, 128.59.199.5, 172.30.0.8
g) Click OK twice and then click on Close
h) You will not be prompted to reboot, but you must reboot for the changes to take effect
i) Confirm that printers show "Ready" status in "Control Panel">"Devices and Printers"
