When booting computer, I have no network before I shutdown bluetoothd

[HY]

It is repeating itself. On every start, I log into my user account on the computer and there is no network, neither on the ethernetcable nor on wlan0. When I click the top-right bluetooth-symbol with the little lock symbol on it and turn bluetooth off, wlan0 "awakens" and I get connected. (At work I have a docking station, same procedure there, only difference is I also have a cable connection. Both connections appear after I turn bluetooth off)
