I have a Broadcom wireless chip which I've managed to wrestle into working with Debian GNU/Linux (I'm on Sid, if it matters). The interface is definitely there:

I have GNOME, and hence NetworkManager, up and running. When I look at GNOME Control Center in the Network pane, the Wireless tab gives information but doesn't list any wireless networks. I've tried connecting to a hidden network, just in case, but this didn't work. I know my network isn't hidden.
Edit: per this wiki page, I've added myself to the
netdev group, and relogged into my session, with no result.
How can I start diagnosing the source of this problem?
