I've been encountering this issue for a couple of days now, since I got back to school. Last year, it was working okay, but now it's broken and I don't really know why. I'm using iwctl for my network manager of choice, and this is my configuration file for eduroam, per the arch wiki:
[Security]
EAP-Method=PEAP
EAP-Identity=anonymous@rpi.edu
EAP-PEAP-Phase2-Method=MSCHAPV2
EAP-PEAP-Phase2-Identity=username@rpi.edu
EAP-PEAP-Phase2-Password=password
[Settings]
AutoConnect=true
(I replaced my user and password in the actual file, but you get the idea)
could it be an issue of conflicting services fighting over dns?

Do you set a custom DNS or do you want to use your school's DNS? (Maybe with systemd-resolved or something else)

Ideally, use my school's DNS. It makes things more simple (i think.) I also have systemd-resolved enabled, so maybe I need to configure it? I don't have any memory of configuring a custom DNS, but I do remember I struggled with a similar issue last year.

What's the rest of the iwd config? And do you get any error message?
Some schools are lazy with their eduroam configuration and use outdated security settings which are disabled on arches.

no error message, and the craziest part, is that it.. well, works in my dorm! But not the other buildings. There isn't anything else in the config besides that network configuration, neither in /etc/iwd; nothing is in that directory either, probably by default.

There not much info
Does iwd able to connect to network or not in other campus building ?
Remove network manager if installed.
Make sure
- If can
-- Get resolvectl status
-- try > resolvectl dns <network-interface like wlan0 > <1.1.1.1 or 9.9.9.9> to change the dns server
-- ping archlinux.org
if can ping then
-- touch /etc/resolv.conf
-- just add nameserver 1.1.1.1
Individual network interface configuration is available in /etc/systemd/network
- file 25-wireless.network

Hi there, so it fixed.. itself? So it makes me think that it may have been the school's fault for it not functioning. Thanks for your help.
