I am completely new to lubuntu / ubuntu. I've installed "lubuntu 14.04.1 alternate" (CD version, as I could not get laptop to boot from usb) successfully on old Lenovo S10. It will network via ethernet cable, but does not find the wireless connection.

I've searched Ubuntu questions and found lots of people have the same issue with Broadcom wireless device.

have run the 

lspci -vvnn | grep -A 9

Network command and know that my 

chip ID is BCM4312 
PCI-ID is 14e4:4315 
kernel driver is wl

Beyond this I am stuck.

Have tried to make sense of the various fixes other people have suggested, but either it does not work or I do not understand how to do what they suggest.

How can I get the wireless running?

Sorry, I need simple instructions please.

Your wifi should be supported with the b43 module with the firmware, so

sudo apt-get purge bcmwl-kernel-source broadcom-sta-common broadcom-sta-dkms

sudo apt-get install firmware-b43-installer and reboot
