Does rfkill unblock succeed in re-enabling your wireless?  (You may have
to install the rfkill package.)  If so, that probably indicates a bug of
some kind in Network Manager.  If not, that probably means that Linux
itself doesn't support re-enabling the wireless device from software (or
at least rfkill doesn't know how), which you could report as a bug against
the relevant wireless drivers, but which is a deeper problem.

One other thing that you could try is to be sure that the firmware for
your wireless card is installed.  Some wireless cards have (often
non-free) firmware that is required to enable various features.  That's
packaged as the various firmware-* packages.
