I have set "Connect to this network automatically, when available" checkbox on network configuration dialog. But after a reboot system does not connect wireless network automatically.

Also the system does not reconnect when network becomes unreachable and then available again.

Reproducible: Always

Steps to Reproduce:
1. Set automatical connect for some wireless network
2. Reboot or turn off WiFi adapter or wireless network 

Actual Results:  
System does not connect to given wireless network, even if "connect" automatically is set.

Expected Results:  
System should connect to the network automatically after reboot or network becomes available.

But when you set up your network settings without "connect automatically" and then (when the network is available) click the ckeckbox and "Ok" the system connects to network (like it should do). But this happens only in the described situation.

If there is some more information you need from me, please do not hezitate  to ask.
