"Wireless disabled in software"

[Timothy Murphy <gayleard eircom net>]

I'm running NetworkManager 0.9.0-1.fc15 under Fedora-15
with kernel 2.6.40-4.fc5.i686.PAE on a ThinkPad T63.

When I hover over the NM icon in the panel I am told
"Disconnected Wireless disabled in software".

I read in /var/log/messages:
-------------------------------
Sep 16 23:32:32 blanche NetworkManager[730]: <info> (wlan0): 
  driver supports SSID scans (scan_capa 0x01).
Sep 16 23:32:32 blanche NetworkManager[730]: <info> (wlan0): 
  new 802.11 WiFi device (driver: 'iwl3945' ifindex: 4)

Sep 16 23:32:32 blanche NetworkManager[730]: <info> (wlan0): 
  deactivating device (reason: 2).
-------------------------------

The network card is Intel/PRO 3945ABG

/etc/sysconfig/network-scripts/ifcfg-wlan0 reads
---------------------------------
ESSID="linksys"
TYPE=Wireless
BOOTPROTO=dhcp
ONBOOT=yes
HWADDR=00:1B:77:04:00:12
NM_CONTROLLED=yes
IPV6INIT=no
MODE=Managed
RATE=Auto
#UUID=113f1f4e-535e-c25b-8849-2c6f770a6501
SECURITYMODE=open
-------------------------------

1. What exactly does "disabled in software" mean?
(I realise the message may not be output by NM.)

2. What does "unmanaged -> unavailable (reason 'managed')" mean?
