The iNet Wireless Daemon (iwd) is a lightweight and stable Wi-Fi manager for Linux systems. However, some configuration is needed for it to work properly on WPA Enterprise (802.1X) networks. For YRDSB:
Create the file with the following contents at /var/lib/iwd/<ssid>.8021x
[Security]
EAP-Method=PEAP
EAP-Identity=<username>
EAP-PEAP-Phase2-Method=MSCHAPV2
EAP-PEAP-Phase2-Identity=<username>
EAP-PEAP-Phase2-Password=<password>
[Settings]
AutoConnect=true
…and then connect to the network normally.
iwctl station wlan0 connect YRDSB-S
