EDIT: Turns out my login information was slightly wrong, and had nothing to do with security.
My school uses EAP for its student WiFi, but there’s no option for “EAP” security (PEAP, LEAP and every other option in KDE’s WiFi security settings wouldn’t connect). I’m pretty sure there was an option for EAP on Linux Lite (my previous OS before kinoite) which connected successfully. Is it possible to use EAP in Kinoite, and how do I enable/use it?
Turns out I just had to add something to the start of my username, and had nothing to do with security protocols.
