Not using ndiswrapper.  Output of lspci -n gives 14e4:4312

I believe I'm really close.  After installing the firmware with
fw-cutter, the load complaint about not finding bcm43xx-microcode5.fw
went away.  And...the device appears to attempt negotiation with the AP.

Found another piece of guidance that the bcm43xx driver has problems
with WEP and shared key...will try open authentication and WPA/WPA2
tonight.
