As of January 2015 the [https://www.computing.vt.edu/content/eduroam preferred method] of wireless access at Virginia Tech is through the [https://eduroam.org/ Eduroam] network. Eduroam is a secure wireless access service that was developed for the use of research and educational institutions. One of the advantages of the Eduroam network over the VT-Wireless network is that you will be able to connect to the Internet at any participating institution using your Virginia Tech credentials. The Eduroam-US site provides a [https://www.eduroam.us/technical_overview technical overview] of how the network authenticates you to the Virginia Tech RADIUS servers.

The following settings are recommended for connecting to the Eduroam network:

* Password: [https://www.computing.vt.edu/kb/entry/3765 Your Network Password]

Due to vulnerabilities in the MSCHAPv2 protocol that allow the protocol to be cracked quickly with a 100% success rate<ref>[https://www.cloudcracker.com/blog/2012/07/29/cracking-ms-chap-v2/]</ref>, it is ''absolutely critical'' that the RADIUS server certificate be validated properly before attempting authentication. Unfortunately, VT is in the process of deprecating a much stronger authentication method, [[EAP-TLS]], and as such, network certificates will no longer be an option.

'''Note:''' As we are pinning the certificate instead of relying on a PKI, when CNS rotates the certificates being used, the configuration will need to be updated to match the new certificate.

Although you can verify connection to the Virginia Tech RADIUS servers you must keep in mind that you are connecting to a network that you do not control. It is possible that there are network monitors in place which can record and potentially modify traffic.
