Wireless on campus: To what network should I connect?
Your wireless network choice depends on your affiliation with the University or eduroam.

For visiting eduroam members
Princeton University is a participant in the eduroam federated network access service. This service allows members from participating institutions to gain instant and secure access to the Princeton University wireless network using authentication credentials from their home institution.

Authentication at Princeton does not require logging in through a portal web page. If you have eduroam enabled and you have authenticated at your home institution, the eduroam wireless connectivity at Princeton is seamless and invisible to you. Watch this page ( for forthcoming instructions on configuring your mobile device. To troubleshoot error messages or inability to connect, see: troubleshooting eduroam.

Please note that limited buildings at Princeton University have eduroam capability at this time. For details, see the Wireless Map of campus and look for the "Wireless Coverage N" areas; these are eduroam capable. The map will be dynamically updated as more areas of campus are upgraded.

For faculty, staff and students (PUwireless)
Princeton faculty, staff and students should connect to the wireless network called PUwireless.

  • Students need to register for Dormnet for Internet access. See: for details.
  • Graduate students should refer to for specific information on wireless availability, and if available, how to register for Mobile Dormnet.
  • Faculty and staff should use the self-help configuration setting shown below (AFTER registering the device in the Host Database) or contact their departmental technical consultant for help.
  • Departments wishing to have OIT Wireless Networking Service extended to their locations are encouraged to contact OIT Hardware Support (8-6199).

Remember that although wireless access is available throughout campus, plugging in to an Ethernet wall box should always be used for intensive computing that requires security and data transfer at high speeds.

For campus visitors (PUvisitor)
Visitor Wireless (PUvisitor) provides service to a device for up to seven days within a calendar month. Visitor Wireless is not intended to provide service to devices belonging to Princeton University faculty, staff, and students, or to longer-term visitors. It does not provide service to wired-only devices. See for complete information.

Remembered networks in the way?
If your computer is registered in the Host Database you cannot use the PUvisitor wireless network. That network is for visitors. If you accidentally select that network, your device will appear to freeze (Windows) or you will receive an error message (Mac OS X). You will  need to wait at least two minutes before attempting to connect (or reconnect). The reason for this two minute interval is that the system remembers your original request for a certain period of time. If your computer doesn't connect correctly after the two minute interval, try rebooting.

PUvisitor is not intended for wireless devices used regularly on campus by  faculty, staff, and students, or long term visitors. The PUvisitor network is limited to 7 days per calendar month and is not available after 3 months of use. If you have previously used PUvisitor and now wish to connect to the PUwireless network, it is recommended that you remove PUvisitor from your device's remembered wireless networks before attempting to connect to PUwireless.
