Enabling Wireless LAN on Lenovo IdeaPad V470 in Ubuntu

We received some Lenovo IdeaPad V470 laptops at work this week. After an install of Ubuntu Natty 11.04 the wireless LAN (wifi) was not working. Quick search on some forums found that an incorrect module (acer_wmi) is loaded. To remove and blacklist the module so that wireless LAN works run:
$ sudo rmmod -f acer_wmi
$ sudo rfkill unblock all
$ sudo su
# echo "blacklist acer_wmi" >> /etc/modprobe.d/blacklist.conf
# exit
Apart from that everything seems to be running smoothly.
