Network Manager not seeing wireless

Everytime I reboot (because the exceptions during a year are countable with countable with fingers) the network-manager says there is no wireless interface--in its own way. What do I mean? Well, when I right click the applet, the 'Enable Wireless' option is greyed-out. In fact, the module wl doesn't load sometimes, but here is why I consider this bug to belong to network-manager-applet:

When I switch off and back on the wireless antenna, the WiFi icon in my computer lights up, indicating that the drivers for the network are loaded. At this point, network-manager-applet still says wireless is not accessible. The next thing I can do to prove you that the wireless is in fact working for the whole system but for network-manager-applet, is to run '# iwlist scan'--that returns some networks detected by my networking hardware; ergo, the card is working, its just that nm-applet isn't seeing it yet.

To prove even further my point, I decided to try out the wpa_supplicant, which is used to connect to networks through the command line interface--find the output attached. The thing is, after letting wpa_supplicant work for a while (during which network-manager-applet still thought that the wireless wasn't on) it got to connect to the network.

System: Ubuntu 10.04 'Lucid Lynx'
App version: 0.8

Please ask for any information you will need in order to fix this bug.
