Thanks a lot, this got me a bit further, but I still was not able to 
configure a wlan connection. I added

allowinterfaces wlan*


to the config and then started dhcpcd without an interface and got the 
/var/run/dhcpcd.sock, group writable for wheel, which I am part of.

I then started dhcpcd-gtk and I got:

** Message: Connecting ...
** Message: Status changed to opened
** Message: Connected to dhcpcd-6.11.2
** Message: Status changed to disconnected
** Message: wlan0: Not associated
** Message: wlan0: Received scan results

** (dhcpcd-gtk:25850): WARNING **: dhcpcd_config_write: Permission denied

** (dhcpcd-gtk:25850): WARNING **: dhcpcd_config_write: Permission denied



The Gui also complained about not being able to write to /etc/dhcpcd.conf.


I got these messages away by calling dhcpcd-gtk as root, but I wonder if 
that is neccessary? Does dhcpcd-gtk have to make changes to dhcpcd.conf? 
If so, no problem, I can also make the file group writable for wheel.


But asides, I got no way to configure any access point, I assume that my 
wpa_supplicant stuff is wrong, too.

I have compiled wpa_supplicant with dbus support, do I have to remove this?

Might be nice to know how and when you invoke wpa_supplicant and what 
you config file looks like.


Kind regards
Tim
