Eduroam: Wireless and Wired Internet For Students And Staff At UO

Eduroam (education roaming) is the secure, world-wide roaming access service developed for the international research and education community. Eduroam allows students, researchers and staff from participating institutions to obtain Internet connectivity across campus and when visiting other participating institutions (almost) by simply opening their laptop.

It is coordinated by CESNET a.l.e. in the Czech Republic. More information can be found at www.eduroam.cz and/or www.eduroam.org including basic maps of WiFi signal coverage.

• More on "Wired Eduroam" can be found in a dedicated article.

The rest of this article deals with wireless eduroam connectivity – the preferred way for students and staff at UO to connect.
