Connecting Mac OS X 10.7 Lion and 10.8 Mountain Lion to Wireless

Cornell has two wireless networks, “CornellWireless”, and “CornellGuest”.  The CornellWireless network is intended for students, faculty and staff.  It gives Cornell users access to all standard resources such as email, networked applications, printing, file shares and Internet browsing. CornellGuest is to be used by people who do not have a Cornell user name and password.  It does not have access to printing, applications or file shares and is very limited in bandwidth.
