To access the school's wireless network you must ONBOARD your personal device. After you have done this one time your device will automatically connect and you won't have to onboard again until the next semester. You can find instructions for onboarding here...
You are only allowed to onboard 2 devices at a time so if you want to bring a different device (phone, laptop, tablet) you will need to delete one. Come by the Student Tech Center L104/L105 in the Library and an ITS can delete devices for you.
