Lenovo z710 and Ubuntu 13.10 wifi auto connect fix

My z710 wasn't auto connecting the wifi at bootup.

rfkill list showed odd modules that were blocked but not shown loaded with lsmod.

The easiest fix was to unload and reload the 'wl' module

rmmod wl
modprobe wl

so i put this into /etc/rc.local, rebooted.

Wifi auto connect worked as soon as i logged in.
