+I wasted 2 hours trying to set up my school's WiFi, so here's a quick reference
+for other students who might've tried connecting but ended up giving up.
+
+> NOTE: I'm using **NetworkManager** on my own installation, so that's what I'm
+> writing this guide for.
+
+1. Install `iwd`
+   ```
+   # pacman -S iwd
+   ```
+	 `iwd` is needed because NetworkManager can't connect to WPA enterprise
+	 networks as stated by the [arch
+	 wiki](https://wiki.archlinux.org/title/NetworkManager#WPA_Enterprise_connection_with_NetworkManager)
+2. Set `iwd` as NetworkManager's backend by adding the following to your
+	 `/etc/NetworkManager/NetworkManager.conf`:
+   ```dosini
+   [device]
+   wifi.backend=iwd
+   ```
+3. Enable/start `iwd.service`
+   ```
+   # systemctl enable --now iwd
+   ```
+4. Create a new file `/var/lib/iwd/eduroam.8021x` with the following contents,
+	 replacing the \<placeholders\> with your own credentials:
+   ```dosini
+   [Security]
+   EAP-Method=PEAP
+   EAP-Identity=anonymous
+   EAP-PEAP-Phase2-Method=MSCHAPV2
+   EAP-PEAP-Phase2-Identity=<username>
+   EAP-PEAP-Phase2-Password=<password>
+   
+   [Settings]
+   AutoConnect=True
+   ```
+	 Keep in mind that your username isn't your student e-mail, but the first
+	 letter of your first name, and 7 characters from your last name, e.g.
+   `Loek Le Blansch -> lblansch`.
+
+After setting all of this up, your laptop should atomatically connect to the
+eduroam network. If you want to connect manually, you'll need to use the
+command-line utility `iwctl`, or use the following command:
+
+```
+$ iwctl station wlan0 connect eduroam
+```
+
+(wlan0 can differ depending on your network card).
+
+You can (and should) still use `nmcli` to connect to normal networks, but I
+haven't tested if it works for eduroam too.
