NetworkManager - have to reboot to change connections

[CS_DBA]

Hi All;

I can plug a hard wire into my laptop and boot up, it comes up connected.

I can boot up with no connection and then tell it to connect to the 
wireless it works fine, but if later I click disconnect for the wireless 
and plug the hard wire (cat 6) cable in it says it's "connecting"  but 
spins until I finally reboot.


Can anyone help me debug this?

Thanks in advance
