FYI I had this problem too and all of the suggestions above did not resolve it. What did fix it was to disable bluetooth PAN networking. I had enabled Personal Area Networking Profile without the bluetooth hardware USB device present. The daemon is not "supposed" to create an interface unless it finds the hardware is present but nonetheless a pan0 interface was present when I did an ifconfig.. By removing the bluetooth pan daemon from my system configuration the NetworkManager wireless problems all went away.
