This summer, the ITS team will be working to implement new wireless network security protocols. As a result, you may begin to see new Wi-Fi networks appearing on your laptop that start with Green_Door. This work is being done in preparation for the Wi-Fi security updates.
There is no action required on your part. You can continue to connect to GreenDoor (no underscore) for wireless access to network resources and the internet. When your computer is configured it will switch automatically to Green_Door.
MAC users: you may see a brief popup window via JAMF when your machine is configured and switches over; if this happens there will be nothing needed and you can safely close the window.
