Apple OS upgrade: Compatibility issue with campus Wi-Fi
Apple's Private Wi-Fi Address feature, introduced in macOS Sequoia and updated for iOS 18 and iPadOS 18, can cause connectivity issues when using campus Wi-Fi networks. The same is true if you update your iWatch or VisionPro.
At this time, OIT's recommendation is to wait to upgrade to the latest Apple OS release. If you do choose to update, OIT strongly recommends that you set Private Wi-Fi Address to "off" for the UCB Wireless, UCB Guest and eduroam networks.

General FAQ
How do I register and get online?
After you select UCB Wireless, open a web browser. If you are not automatically redirected to the network sign-in page, then go to www.colorado.edu or http://neverssl.com/. The first time you use the network, you will be asked for your IdentiKey username and password to register your computer on the wireless network. To help ensure that only campus affiliates use the CU wireless network, you may be asked to update your registration annually.
What if my device doesn't have a web browser?
If your device does not have a web browser, you will not be able to access the UCB Wireless registration page. In order to connect the device to the network, it will need to be registered manually by the IT Service Center. You will need to provide your device's MAC address.
What is an SSID?
SSID stands for Service Set Identity/Identifier. It is a name that represents which wireless network a user is attached to. This is also called the "Network Name" by some vendors. CU Boulder's SSID is "UCB Wireless."
Can University guests/visitors use the wireless network?
Yes, a guest can use UCB Guest Wireless, but must be sponsored by a CU Boulder affiliated student, faculty, or staff member. Learn more about UCB guest wireless.
Can I use my smartphone on the wireless network?
Yes. To learn more, check the UCB Wireless Help documentation.
What about wireless security?
Wireless network security is a serious issue. Wireless is not only a shared medium, but also a medium that is broadcast via radio waves which means that anyone with a wireless card could monitor your network traffic, including your passwords, account numbers, etc. Thus the data is inherently insecure. In order to protect your data, please ensure it is encrypted using SSL, SSH, or VPN. Read more about IT Security, VPN, and Wireless Security.
