Lenovo B560 With Atheros WiFi might have a issue with Ubuntu 11.04 - a work around for that

 After I got my new Lenovo B560 laptop I was thrilled and I was jumping in joy and being a Ubuntu buff I installed the latest and the greatest release from the grate Linux distributor Natty 11.04. Downloaded a iso file and using unetbootin created the bootable usb and use that boot in to my new Lenovo.
 As soon as I got in to the system what I noticed was that my wireless was not working so I kind a freaked and did a second download od the ISO and re-did every thing from the binging but with the same result. So with out no option I installed WiNDOWS and checked the wireless and bam it was working at that point I realized that theres some kind of a bug or a issue in the Ubuntu distro. So being a very long campaigner I knew that if there's a issue I could find a solution at the grate community. I asked my good friend Mr.Google who found me this answer and it worked like a charm for me thats why I'm posting this here hoping this will help any other one with the same issue.
There are two way of doing this first do the temporary one.

sudo rmmod -f acer-wmi
sudo rfkill unblock all
rfkill list all

After the above steps your wireless starts to work then make it permanent by doing this,

sudo gedit /etc/modprobe.d/blacklist.conf

Add the below line at the end of the file

blacklist acer-wmi

Proof read this before saving and if everything is ok then save it.
Now do this

sudo gedit /etc/rc.local

Just before the word end put this

rfkill unblock all

Proof read it twice if ok save it.
Now reboot your system, once you log in your wireless should work with out any problem 'cos this solved my issue.
Hope this helps and cheers.
