Wireless can be disabled due to several things: by hardware switch, driver 
issues, user disablement, etc.

Please check and report output of these commands:
1. rfkill list
2. nmcli nm
3. cat /var/lib/NetworkManager/NetworkManager.state

Also include /var/log/message where we will see state of Wi-Fi in NM logs.


There was a change to this to decouple rfkill state and user preference on Wi-
Fi.
See:
rpm -q --changelog NetworkManager | head -n 5
* Mon Nov 01 2010 Dan Williams <dcbw redhat com> - 0.8.1-10
- core: preserve WiFi Enabled state across reboot and suspend/resume

* Fri Oct 15 2010 Dan Williams <dcbw redhat com> - 0.8.1-9
- core: fix suspend/resume regression (rh #638640)
