Joining Eduroam or Purple Air

Williams is transitioning our primary wireless connection from Purple Air to Eduroam.   After connecting to Eduroam at Williams you will be able to use the Eduroam network at other participating colleges and Universities.  It is fine to continue using Purple Air for now, but the next time you need to connect choose the Eduroam network.

To join Eduroam you will log in with your email address (e.g. [email protected]) and password and then trust or accept a new certificate.  Examples of what you might see are listed below.

For help you can contact the Faculty/Staff Support Desk at 413-597-4090 or email [email protected] . Students should contact the Student Support Desk at 413-597-3088, send email to [email protected] or stop by the Student Support Desk in Sawyer Library, 2nd floor Center for Educational Technology.

Click Continue.  You may then get an authorization window which is your local computer account and the computer password (used to install software or make changes):


iPads and iPhones may get a prompt to accept the new certificate.  Click Trust or Accept.

 


 

Windows 10 computers will get a security alert regarding the new certificate.  Click Connect to continue.

 


Android phones, chromebooks or tablets often require a manual configuration. You may need to change the “EAP Method” to “PEAP”, then log in. So far in our testing these devices connect without needing to accept the new certificate.

Newer Android phones will ask for the following, and more closely follow the setup for a Chromebook or Google Pixel.

Windows Phones simply accept the new certificate.
