This post provides very simple instructions for connecting to the uog-wifi-secure network at University of Guelph (specifically proven working in 2018). These instructions can likely be adapted to any WPA-enterprise network utilizing EAP-PEAP (MSCHAPv2) and any device using wpa_supplicant. From raspbian you can edit two files,
/etc/network/interfaces (to enable our interfaces, i.e. turn them on) and
/etc/wpa_supplicant/wpa_supplicant.conf (for entering the required parameters).
