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.

Do other devices interfere with wireless?
Wi-Fi communication is extremely susceptible to interference caused by competing radio transmissions that operate in the 2.4GHz and 5GHz bands. Wi-Fi interference can result in low to no wireless signal, extremely slow download speeds, dropped Wi-Fi connections, and increased delay for internet browsing.
Note: Personal Wi-Fi access points are prohibited in the residence halls.
Is wireless bad for my health?
Testing done on wireless network devices indicates no confirmed health risks at this time. You should read the health information provided by your wireless card manufacturer and follow their recommendations.
