The installed packages include wpa_supplicant-2.0-1.2.1.armv7hl
The Freien Universität Berlin has a page on linux with eduroam. There's a sample eduroam-wireless.conf and instructions. I think I know how to edit the sample .conf for my own university but I don't know how to run wpa_supplicant so that it connects, stays connected through restarts or leaving and then returning to an area served by the network. And I don't know what effect this will have on the battery.

Basically I feel like I have the jigsaw pieces but don't know how to put them together.
