| − | 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]]. In July, 2013 VT_WLAN was superseded by CONNECTtoVT-Wireless, is an unencrypted, captive portal wireless network designed to set up connecting to VT-Wireless. Internet access is not available on it. Connections to VT-Wireless are secure by default, and has one of two different methods to connect.

| |
| − | As of September 16th, there is an issue present in the Cisco wireless controllers that Virginia Tech uses which causes 802.11n connections to fail for many users, including Linux users on Intel wireless chipsets. Disabling 802.11n is a workaround until it is fixed. This can be done in Arch Linux and Ubuntu by running:
| |
| − | <pre>echo "options iwlwifi 11n_disable=1" >> /etc/modprobe.d/intel-802.11n.conf</pre> as root.

| − | The best option is [[EAP-TLS]], which provides strong, two-way authentication to ensure that neither you or the authentication server can be impersonated. Unfortunately, setting up EAP-TLS can be somewhat involved because it requires a certificate to be installed on the device.
| |
| − | | |
| − | Using [[PEAP-MSCHAPv2]] is less secure as the authentication method can be broken with sufficient resources in a short ammount of time. However the authentication is encrypted and the encryption key is authenticated and it is significantly simpler to set up and use.
| |
| − | | |
| − | CONNECTtoVT-Wireless is an unsecured captive portal wireless network. It is used for setting up VT-Wireless on your device. This is entirely optional and the instructional pages for [[PEAP-MSCHAPv2]] and [[EAP-TLS]] do not use it. There have been some reports that using this method causes problems, possibly related to the software it uses. The network is locked down to only allow access to pages that help connect the user to VT-Wireless. It uses [[XpressConnect]].
