[SOLVED] Thinkpad E570 can't connect to university WiFI (eduroam)

Hello everybody here,
My university has updated it's WiFi setup somehow and now my wpa_supplicant refuses to connect.
The config worked like a charm before but now it's no dice. Weird thing is that my wpa_supplicant logs show that wpa_supplicant 'Authenticated succesfully'
only to then after a while disconnect with 'reason=7'. Sometimes it disconnects saying 'reason=3' so the error isn't consistent at all.

I have searched around the forum for anwsers but the most common anwser i could find is 'powermanagment issues' but i don't have powermanagement installed (altleast i don't think i did)

Here is the output of me manally starting wpa supplicant.

I use the following configuration to connect with my university.

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
fast_reauth=0
update_config=1

network={
	ssid="eduroam"
	scan_ssid=1
	key_mgmt=WPA-EAP
	eap=PEAP TTLS
	identity="_UNIVERSITY_EMAIL_ADDRESS_"
	anonymous_identity="anonymous@windesheim.nl"
	password="_SUPER_SECRET_PASSWORD"
	phase1="peaplabel=0 peapver=0"
	phase2="auth=MSCHAPV2"
	priority=100
}

If i need to share more logs don't hesitate to ask since I don't really know what logs would help with resolving this issue.

I fixed the issue by switching to NetworkManager instead of using wpa_supplicant.

Okay. I managed to switch to NetworkManager and now it works.
I know having such a nooby a thread hurts my Arch Linux creds but still i now have internet so i'm happy.

Marking this thread as solved.
