how to manually activate my broadcom wireless?

["Robert P. J. Day" <rpjday@crashcourse.ca>]

  i'm sitting in front of a lenny system which does not have either
network-manager or network-manager-gnome installed on it, but i would
dearly love to activate the broadcom wireless.

  the installed broadcom firmware worked fine a while back when the
manager packages were installed, and the appropriate modules are
loaded (b43, etc.).  i can use "iwlist wlan0 scan" to see a number of
visible, local networks, and "iwconfig wlan0" shows me that wlan0 is
currently associated with exactly the network i'm trying to associate
with.

  so, without network-manager-gnome, what's the cmd line to activate
that wireless interface?  i've tried:

  # ifconfig wlan0 up

which simply returns but doesn't give me wireless.  any hints on the
magic incantation?  thanks.
