Troubleshooting

If you can’t log in:

If you’re repeatedly prompted for your name and password and are still unable to successfully connect to the BU (802.1x) SSID, you may need to synchronize Kerberos. While connected via Ethernet or “BU (requires VPN),” simply go to the Kerberos synchronization page (pictured below) and click the “log in” button.

Make 802.1x the default SSID for BU:

If you had previously used either “123″ or “BU (requires VPN)” or “BU Wireless Help” your computer may try to connect to that network first. In order to be sure your computer connects first to the BU (802.1x) SSID, follow these steps:

  1. Open the System Preferences by going to the Apple menu and choosing it:Apple Menu -> System Preferences...
  2. Click on the Network icon in System Preferences.Network System Pref
  3. Click on AirPort in the left column, and then on the Advanced… button near the bottom right corner of the window.AirPort preferences
  4. Drag and drop the names of wireless networks so that BU (802.1x) is higher in the list than BU (requires VPN). Then click once on 123 or BU Wireless Help and click the “-” button to remove it from the list.
