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
What areas of campus have wireless?
Wireless is available throughout the vast majority of the CU Boulder campus.
What is an SSID?
SSID stands for Service Set Identity/Identifier. It is a name that represents which wireless network a user is attached to. This is also called the "Network Name" by some vendors.
What SSID should I use?
- Faculty, staff, and students with an 802.1X capable devices (most modern devices) should use eduroam.
- Campus visitors whose institution does not participate in eduroam, should use UCB Guest.
- Faculty, staff, and students with older devices should use UCB Wireless.
Do other devices interfere with wireless?
Yes, any 2.4GHz or 5GHz device that is near the wireless access point or wireless card can affect performance and may negatively impact your wireless connection. These devices are usually microwave ovens in close range, cordless phones, cameras and other 2.4GHz wireless devices. A non-University of Colorado access point can interfere with the CU wireless network, so it is necessary to coordinate with OIT if you wish to set up a wireless access point. Deployment or installation of your own Wi-Fi access point is prohibited.
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.
If you are interested in additional information, the FCC has a detailed Wireless Devices and Health Concerns article.
