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.
After updating to the latest Apple OS release, 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 UCB Wireless, you will 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. 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.
Can campus guests or visitors use the wireless network?
Yes, guests can use 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.
