How to connect securely in the U.S. and abroad with eduroam

Planning a trip to another university? Now Ohio State students, faculty and staff have a new option for connecting securely throughout the U.S. and abroad --the eduroam network. Created in by European universities in 2003, the network allows you to access a secure, encrypted connection at any participating eduroam universities without having to gain guest credentials. There are thousands of eduroam hotspots to join, eliminating data roaming charges. 

Before You Travel

OCIO is broadcasting the eduroam wireless network across all campus locations – not only for visiting users of participating institutions – but also to allow Ohio State users to test their configuration prior to departing for a trip to a participating institution. To get connected, you can access our knowledge base for instructions (article #KB04594), visit the BuckeyeBar, or contact the IT Service Desk at 614-688-HELP (4357).

Please note, the use of eduroam is not meant to replace the “WiFi@OSU” network used by campus visitors, nor the existing secure “osuwireless” network as used by current students, faculty and staff.
