Description of problem:
After reboot or wake-up after sleep mode Networkmanagaer tries "forever" to connect to wifi network, but does not succeed. ifconfig shows no ip address for wifi card. Manually running dhclient can get an ip address, but NetworkManager still shows "connecting".

I found a workaround by deleting all files in /var/lib/NetworkManager/ and then running: systemctl restart dbus-org.freedesktop.NetworkManager.service

The wifi connection is working after this.

Version-Release number of selected component (if applicable):
0.9.10.1
1.git20150105.fc21

How reproducible:
Every time after reboot or wakeup from sleep mode.

Steps to Reproduce:
1. Have a working wifi connection
2. Press Alt-Shutdown button from system menu to go to sleep mode.
3. Wake up via Esc and login again.
4. NetworkManager shows "connecting", but does not succeed.
5. rm /var/lib/NetworkManager/*
6. systemctl restart dbus-org.freedesktop.NetworkManager.service
7. NetworkManager connects.

Actual results:
Need workaround everytime after sleep mode

Expected results:
NetworkManager reconnects automatically without workaround.
