MacSecure to be removed on July 8

In an ongoing effort to simplify access to the campus wi-fi network, University Technology Services (UTS) will be reducing the number of wi-fi networks available to the campus community.

The network named “MacSecure” will be removed from service on July 8, 2020 and will no longer appear as an option in your network list after that date.

Wi-fi users should ensure they are using the network named “Mac-WiFi” which appears in your available network list. Please rest assured that Mac-WiFi has identical security and access features as MacSecure. Since they are identical, there no need to continue offering both networks. We encourage you to begin using Mac-WiFi immediately.

Students living in residence should continue to use “Reznet-WiFi”.
