If you are using Eduroam in your home university, you can use it to access the UPC wifi.

If not, you can use the "guest" option (click in "convidat/guest").

After you make the enrolment in UPC (when you arrive to UPC), you will get the UPC username in order to access the wifi and all the different UPC platforms (Atenea, e-secretaria, ...). From then on, you can use your UPC username and password to access the Wifi through Eduroam.
