I have a new laptop with a centrino wireless card.

I installed ubuntu on it and all seemed fine until I upgraded the kernel, and rebooted.

My wireless stopped working despite toggling the wireless button.

rfkill list returns the following:

0: phy0: Wireless LAN
    Soft blocked: yes
    Hard blocked: no
1:hci0: Bluetooth
    Soft blocked: yes
    Hard blocked: no

the hardware switch only toggles the hard blocks.

How do I turn off the software blocks? I have tried 

rfkill unblock all

without success. What next?

sudo modprobe -r acer-wmi
cd /etc/modprobe.d
sudo nano blacklist.conf
In that config file, just add
blacklist acer-wmi

Just use these commands and reboot. thats it
