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.

Features
CU Boulder's wireless internet provides easy access to the network from any Wi-Fi enabled personal device throughout campus. CU Boulder has three Wi-Fi options for use on campus: UCB Wireless, UCB Guest and eduroam.
Between the three networks, wireless internet is available in approximately 90% of all indoor building space on campus—and even on the Buff Bus.
Which network should I use?
| Network | Who may use it | Resource access | Authentication |
