Internet Connection Types
To connect to the Internet and the NU Network, choose from dial-up, digital subscriber line (DSL), or cable modem services. NUIT recommends DSL or cable modems for service that most closely matches on-campus connection speeds and allows for quicker access.
See NUIT's Internet Provider Comparison for information about local and national vendors.
