A small number of Mac users have expressed some intermittent issues while connecting to the Wireless RU-Secure and RYERSON networks, as well as the Wired captive portal network on campus. The symptoms are showing as declined connection and/or not being able to download the authentication web page.
After looking into the problem, CCS has discovered that there is a issue with OSX 10.7.2 (Lion) in regards to HTTPS, WPA2 and captive portal certificate handling.
The solutions offered by Apple/Mac involve disabling the security checks of the certificates within browsers or within the Key-chain itself. CCS does not recommend taking this action as it leaves the user’s computer vulnerable to unverified certificates. CCS will continue to investigate the issue.
We apologize for the service interruption.
