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.
