Conference Frequently Asked Questions

Yale provides visitors two Wi-Fi network options:

  • YaleGuest
  • Eduroam

YaleGuest is a public, insecure wireless network available for anyone’s use, but has limited network access. Due to security reasons, certain programs and functionality may not be accessible via the YaleGuest network, e.g., Dropbox, Skype, and Box.  

If possible, we recommended you use the Eduroam wireless network.  Eduroam (education roaming) is a secure, world-wide roaming access service that allows students, researchers and staff from participating institutions to obtain Internet connectivity across campuses when visiting other participating institutions.

If your institution is a partneraccess the Eduroam network by selecting Eduroam from the Wi-Fi list on your mobile device and sign-in using your home institution’s credentials*. View Eduroam’s complete listing of U.S. participating schools; International visitors can look for institutional listings on this country page.

For additional details, please contact your institution’s IT department or search your institution’s support page.

*Credential format is typically ID@UniversityName.edu, e.g., YaleNetID@yale.edu or SUNetID@win.stanford.edu
