I'm going to catch hell for this but I'm old school on this...
Nuke network-mangler and if you want dhcp to handle its addressing, try
wicd, I've been a lot more successfull with it than N-M.
Then dmesg to see what udev called it _this_ time, and "man interfaces"
to see how to add a stanza for it to the interfaces file. You WILL have
to be root to edit it, and /etc/resolv.conf.
Oh, and welcome to the broadcom victims list with its cast of millions. I
never did make the broadcom bcm-4318 radio in my now 15 year old HP
lappy work for more than 2 or 3 minutes, even with the winders drivers
running the installed xp when IP bought it. But there, the xp only
lasted a couple months, replaced with mandrake at the time. xubuntu
atm.
A netgear usb dongle plugged in and Just Worked(TM) once I had edited the
interfaces file to add it, but I use host files so all of my machines
have a fixed known address anyway. On a home network its handy but
hauling it to a motel and using their wifi will mean some editing.
