Wireless could be unavailable from various reasons. Please include 
NetworkManager logs from /var/log/daemon.log file.

One possible reason is that wireless is blocked by RFkill. To check this run:
rfkill list
If there is a soft block, you could unblock it by:
rfkill unblock all

More info in man rfkill

BTW, the advice from Timothy is OK, but it's been aimed for James and is 
mostly Fedora specific.
