Problem was apparently due to conflict with Bcm wireless driver
installed during installation of 12.04, which effectively prevented
ethernet connection. Instructions at
http://askubuntu.com/questions/55868/how-to-install-broadcom-wireless-drivers-bcm43xx
allowed ethernet to be activated (by removal of bcmwl-kernel-source) and
then wireless driver to be installed and activated. So 12.04 now appears
to be working OK on my Dell laptop.
