William Paterson University uses ISE (Identity Services Engine) authentication for all network connections. If you are logged into a machine and are unable to print, access certain websites or get / stay connected to WPU-Folders, you may not be authenticated to ISE

Wifi symptoms typically include the wifi icon repeatedly trying to connect or sometimes an exclamation point. For ethernet connections, including those made via a USB or Thunderbolt to Ethernet adapter, there will simply be limited connectivity with no other signs of issues.

To remedy this problem do the following:

1) Open System Preferences

2) Select the "Network" pane.

After a bit of background processing you should either be connected to Wi-FI or Ethernet.


A good working connection will look like the below. Note the "disconnect" button, the "Authenticated via" line as well as the timer:
