Killed the kded4 process and wireless was gone. Then I ran kded4 --check and this was the output:
alfabravo@alfabravoTiger:~$ kded4 --check Connecting to deprecated signal QDBusConnectionInterface::serviceOwnerChanged(QString,QString,QString) ntrack backend selected and created: ntrack-libnl1.so kbuildsycoca4 running...
