Have you performed the following:
- systemctl daemon-reload
- systemctl restart wpa_supplicant

If so then verifying is with:
- ps aux | grep wpa_supplicant should be enough

Nevertheless you provided with the latest comment info we requested, so there
is no need to restart wpa_supplicant in debugging mode anymore:

The correct name is: wpa_supplicant (note the _underscore_)

So the conclusion:
You wifi network is configured with WPA1 protocol (if you are able to change
it, we recommend you change it to WPA2, which is much more secure).
Up to the current mainline version of wicked, WPA1 protocol was not supported.
It has been implemented recently with the commit:

https://github.com/openSUSE/wicked/commit/606b50d601876e81aaaca9db26cd0f103d22ab29

Therefore please test with the latest master build RPMS if this solves the
problem for you. The RPMs can be found in the following master repository:

http://download.opensuse.org/repositories/network:/wicked:/master/openSUSE_13.2/

The solution will be also available with the next wicked release: 0.6.16.
