It seems the preference could be set by adding the following line into /etc/connman/main.conf
PreferredTechnologies=wifi,cellular
I'm currently running with this configuration for about a week and the wlan/cellular switch seems to be much more reliable.
Also it seems it has a good influence on the "Problem with connection" errors. During the week I have only seen that problem once and it was sorted out by the system itself without reboot. Normally I have faced the problem mentioned several times a week.
If some other people could test the config to confirm/disprove, it would be highly appreciated.
Just deactivate mobile data when not wanted. As long as Wlan can be accessed it should in any case stick with it.
ramoth ( 2013-12-29 01:48:16 +0200 )edit@ramoth Yes. I do that as a workaround but the switch to mobile data usually happens unnoticed. I also do not want to disable the mobile data completely. I would just like to switch to it automatically once there's no way to use the WLAN(s).

ramoth ( 2013-12-29 02:00:39 +0200 )edit@ramoth It should but currently it's not. Often I have found the phone is using mobile data while there was a usable WLAN present at the very place. Also the phone should switch back to WLAN once it's usable again which also did not happened to me many times.
strnous ( 2013-12-29 02:21:55 +0200 )editAlso it should be possible to prefer the mobile data over WLAN if the user wants for whatever reason.
