Since the fall of 2008, there have been two wireless networks on campus. One network, called '''VT-Wireless''', encrypts all traffic and is secured with EAP-TLS or PEAP-MSCHAPv2. The other network, called [[VT_WLAN]] was an unencrypted network captive portal using PID authentication. In July, 2013 VT_WLAN was superseded by CONNECTtoVT-Wireless, an unencrypted, captive portal wireless network designed to set up connecting to VT-Wireless without offering Internet access. Due to user issues faced during deployment, CONNECTtoVT-Wireless began offering captive portal access to VT users. In January 2015, '''eduroam''' access was enabled, allowing members of any eduroam-affiliated institution to use wifi at any other institution. Connections to VT-Wireless and eduroam are secure by default, and has one of two different methods to connect.
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 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://eduroam.us/technical_overview technical overview] of how the network authenticates you to the Virginia Tech RADIUS servers.

==A word of caution==
Although you can verify that you are connecting to the eduroam network and validating your connection against 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.
We encourage you to take precautions against network eavesdropping and mischief (on the Eduroam network, and in general). Potential countermeasures that one might want to employ include using [https://www.eff.org/HTTPS-EVERYWHERE HTTPS when connecting to sites], using a [https://www.computing.vt.edu/content/virtual-private-network VPN], or using the [https://www.torproject.org/ Tor Browser Bundle].
For general tips on improving your security while using the network, consider reading reading the EFF's [https://ssd.eff.org/ Surveillance Self-Defense] tips and/or contacting the [https://security.vt.edu/ Virginia Tech Information Security Office].
