Fedora Installation :: Wireless Network Configuration - B43 Adapter Grayed Out

I am doing network config of my laptop. I'm new to Fedora, so I'm not sure how it goes ...
I have an Ethernet device (eth0) and a wireless device, wlan0
Status in system->administration->network:
Tab devices:
eth0 : active
wlan0: inactive
Tab Hardware:
eth0: system
wlan0: configured (description: b43)

Double clicking on the wlan0 line gets you to Network Adapters Configuration, where adapter b43 grayed out) is associated with device wlan0. So far, so good (I did all the fwcutter stuff, so I assume this is the result). When I installed the system (from installcd, then update, then install broadcom-wl, ...) I configured it to be started up with network manager, automatically on startup. I managed to get it working exactly once in that session.

Problem is, it doesn't start up and the wireless is not even visible when you click the network manager icon. For that matter, eth0 does not start automatically either, but at least there is a button to start it in network manager. Coming back to the tab devices, clicking on wlan0 allows you to click on the activate button ... but there it says: Cannot activate network device wlan0! b43 device wlan0 does not seem to be present.
