Wireless Setup for Mac

Note: Ethernet connections are the fastest and most reliable connections on our campus network. If you are in your
office or dorm room, we strongly encourage you to use a wired Ethernet connection instead of wireless. Wireless
should only be used in locations where an Ethernet jack is not conveniently available.

TrinAir Troubleshooting

TrinAir to reset the connection.
