I encounter the same problem with NetworkManager listing wireless unavailable. It occurs every time I disable and try to re-enable the wireless using the NetworkManager in Oneiric running gnome-shell. It is not exclusive to gnome-shell because I find the same behavior when running Unity. A workaround that works for me is to restart network service.
