I get the problem as described on Ubuntu 12.04, with a Sony Vaio SVS15116 laptop, and wifi (from lspci):
02:00.0 Network controller: Intel Corporation Centrino Advanced-N 6235 (rev 24)

Every time I manually uncheck "enable wireless" from the networking menu (default unity setup), it stays greyed out. Sending "sudo rfkill unblock all" then disable/reenable networking, it is fixed.

While broken, "rfkill list all" gives:

0: sony-wifi: Wireless LAN
 Soft blocked: yes
 Hard blocked: no
1: sony-bluetooth: Bluetooth
 Soft blocked: no
 Hard blocked: no
2: hci0: Bluetooth
 Soft blocked: no
 Hard blocked: no
3: phy0: Wireless LAN
 Soft blocked: yes
 Hard blocked: yes

The laptop has NO hardware wireless switch, and NO function key combination for wifi (they rely on a proprietary program in windows to manage wireless... yuck).
