Logging on to "isunet"

When your computer is in range of the "isunet" wireless network on campus, Windows will display a notification bubble in the lower-right corner of your desktop next to your clock.

When this happens, click on the notification bubble. Windows will present you with a log in window. Enter your ULID and password; leave the Domain box empty.  Then click OK and you should then be connected to the isunet wireless network.

Windows Vista and Windows 7 saves your ULID and password (this is called "cached credentials"). The next time your computer is within range of "isunet" it will automatically connect. After you change your password, your computer's cached credentials will be out-of-sync with "isunet" and you will see the same notification bubble as before. Click the notification bubble and type your ULID and password as you did the first time.
