Connecting to WPA2/PEAP/MSCHAPv2 enterprise wifi networks.

Hello,

I am having trouble connecting to my school's wifi using networkmanager. I'm using the nmcli connection editor to set up my system connection.

This is what my network file looks like:

[connection]
id=MYID
uuid=MY_UUID
type=wifi
interface-name=wlp3s0

[wifi]
mode=infrastructure
ssid=MY_SSID

[wifi-security]
key-mgmt=wpa-eap

[802-1x]
ca-cert=/etc/ca-certificates/trust-source/anchors/ca.crt
eap=peap;
identity=USERNAME
password=PASSWORD
phase2-auth=mschapv2

[ipv4]
dns-search
method=auto

[ipv6]
addr-gen-mode=stable-privacy
dns-seach=
method=auto

When I try to activate the connection, it is stuck on

Passwords or encryption keys are required to access the wireless network 'SSID'.
connecting (need authentication)

before returning: 'Error: Connection activation failed.'

Here is the output from journalctl -ex (often times it says failed to provide secrets that were required).

Re: Connecting to WPA2/PEAP/MSCHAPv2 enterprise wifi networks.

Is this for connecting to eduroam?

If so, check out the instructions at this link:

https://uwaterloo.ca/information-system … nux-ubuntu

Those instructions worked for connecting at my school in NetworkManager on Ubuntu, just substituting the correct ca-cert from my school's instructions. I personally have not tried NM on my Arch install, but netctl has not worked for me, though many others have been able to get it to work in Arch.

Re: Connecting to WPA2/PEAP/MSCHAPv2 enterprise wifi networks.

Try to remove the certificate line under the [802-1x] category and add "auth-alg=open" under [wifi-security]. If you're lucky it might work.
If it doesn't then just try mixing them up a bit and try with different combinations.
