Apple has announced that there is a known issue when an OS X computer is trying to connect to a Wi-Fi network that uses TLS, PEAP, or TTLS for authentication (which includes Algonquin College). There may be a delay of up to ten seconds before authentication completes.
There are steps you can take to fix this issue. Go to this Apple support page for the steps. If you are not comfortable following these steps, take your Apple computer to an Apple Retail store for assistance.
