I am not an expert at this topic, so I'll try to describe as detailed as possible, how I am able to connect to the WLAN at my university (using my laptop running Arch Linux as well as using my Jolla with a manual configuration/connman disabled) and what seems to be the problem using Jolla with connman.

This is my working wpa_supplicant config file for the laptop:

proto=WPA RSN

which as well works with wpa_supplicant on my Jolla if I configure the WLAN adapter manually, i.e. step by step:

# first I have to kill connman
systemctl stop connman
# setting up wpa_supplicant
wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant/eduroam.conf
# I get an IP-address with udhcpc that has to be added manually
udhcpc -iwlan0
ip addr add <ip I got from udhcpc/suffix> dev wlan0
# The default gateway and DNS information stay constant 
ip route add default via 'address of default gateway at my uni'
# then I add some lines to /etc/resolv.conf:
    nameserver <nameserver ip>

This leads to a working internet connection but obviously is not very comfortable, because connman has to be stopped...

I have tried to create a connman config file /var/lib/connman/wifi_eduroam.config with the following content but there is a problem while trying to set up the connection.



I guess, that the connection fail is linked to the lack of a config parameter for anonymous_identity in connman according to connman/connman.git.

Well, as I already said, I am not an expert, so please forgive me, if this problem has been solved already or if there is some stupid mistake ;)

For me personally it would suffice if there was a possibility to avoid having to stop connman while using the eduroam network. Maybe there is some way to tell connman to use my wpa_supplicant config file?

Thank you

well, I read this thread, but could not get the workaround using the connman config file working, so I should rather ask, if it is currently possible to get connected to my uni's eduroam using connman. Thanks for your help ;)

Something similar has already been discussed here: There seems to be no fix currently. My university's eduroam also supports connecting without an outer/anonymous identity but the real solution would of course be to include this in connman.

IMO this is a missing features and shouldn't require any workarounds in a proper implication of WLAN connectivity

UPDATE: stitran found out that it is connman's case-sensitive interpretation of the config file so a change in EAP=TTLS to EAP=ttls solved his problem.

@stitran don't change the cacert line - I am at and had exactly the same problem

Thanks for your suggestion, but this seems not to solve the problem. (Connman tries to connect but fails after a while.) At my uni's eduroam some kind of config parameter like is required.

stitran ( 2014-09-13 15:57:06 +0300 )edit

that parameter is said to be needed at too but it works without it, what does wpa_supplicant tell when connecting (wpa_cli)?

chemist ( 2014-09-13 17:46:21 +0300 )edit

I'm sorry, I am not used to wpa_cli ;) So which output of wpa_cli are you interested in exactly? While connecting successfully or should there be some feedback of wpa_cli while Connman tries to connect, but fails? The config file of uses three differing parameters (pairwise,group,proto) in comparison to my working wpa_supplicant config file (maybe this is important)

stitran ( 2014-09-14 00:27:27 +0300 )edit

the failing output, it will show what part is failing, the reason why you are unable to connect. For, my eduroam connman config file is exactly what is shown above. No pairwise or group setting. Well I wrote "ttls" instead of "TTLS" and my file is called wifi_eduroam.config... I tried just as you did, find a way to enter outer identity and use the telekom root cert but that is what I ended up with.

It works!! Writing TTLS lowercase solved the problem ;) Thank you very much! I will 'mark your answer as correct' as soon as you edit the eap=ttls line.
