Wireless at Princeton: Which network is right for me? What is eduroam?
Your wireless network choice depends on your affiliation with the University or eduroam. All faculty, staff and students at Princeton are strongly encouraged to configure their devices for eduroam first, and PUwireless second.

eduroam (education roaming) for everyone
Princeton University is a participant in the international 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. If you are eduroam-enabled and you have authenticated at your home institution, the eduroam wireless connectivity at Princeton is seamless and invisible to you. For Princeton faculty, staff and students, you can travel the world and use eduroam for wireless connectivity at all federated participants.

  • Remember that your login netID for eduroam is your; not just your netID.
  • You need to have connected at your home institution first before travelling.
  • See how to troubleshoot eduroam connectivity if you are having troubles connecting at Princeton.
  • See the Wireless Map 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 PUwireless network if they are in an area of campus not yet upgraded for eduroam.

  • Students need to register first for Dormnet. See for details.
  • Graduate students should see 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.

Configuration settings


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.
