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.
