As a CBS student, you have exclusive access to CBS-Secure by connecting using your Lifetime ID (FLastname19) and Business School password. You will need to accept a security certificate, as with any other secured/encrypted wireless network which requires authentication.
Once in one of the two Business School buildings, you will be able to connect to the CBS-Secure signal. The below instructions will help you complete your connection. You have the option of connecting multiple personal devices, however, depending on the settings and configuration of your device(s), these instructions may vary:
Mobile Devices (tablets and smartphones)
iOS (Apple iPhone, iPad, iPod touch)
Secure Wi-Fi networks are password protected and have by their names.
- From your Home screen, go to Settings > Wi-Fi, and make sure Wi-Fi is turned on
- Tap CBS-Secure then enter your Lifetime ID (FLastname19) and CBS password, then tap Join
- Trust the cbs-secure.gsb.columbia.edu certificate
After you join the network, you'll see next to CBS-Secure and in the upper-left side of your display. If you're having trouble with your login, try resetting your CBS password, then try again.
These instructions are for Android devices running 7.0 (Nougat) and up. Since Android is different across some devices, your menu options may vary slightly depending on the version of Android that you are running. Learn how to check your Android version.

These instructions describe the basic steps for connecting to CBS-Secure on your personal laptop.

Prioritize CBS-Secure over other Columbia W-Fi networks (Mac)
By default, your Wi-Fi connection attempts to join the wireless network your Mac was most recently connected to. If you're in an environment where you have access to more than one wireless network, you can set network priority in order to always join a preferred network. You’ll probably want to prioritize CBS-Secure above other Columbia networks so you don’t accidentally end up on CBS-Guest or any other Columbia networks while you're in the Business School building.
- Choose Apple menu > System Preferences, then click Network
- Click Wi-Fi (left pane), then click Advanced
- In the Wi-Fi tab under Preferred Networks, drag CBS-Secure above all other Columbia University related networks.
- Click OK > Apply to save changes
This gives CBS-Secure a higher priority which means your computer will try to join it before any other Columbia network.
Most corporate users who are connected to a domain and/or normal users with certain authentication restrictions in place may need to manually connect to CBS-Secure in order to access the Business School's network. Learn more about the things to keep in mind if using a corporate computer on the Business School's network infrastructure.
