Enable Wireless in Linux

      Wireless is disabled in Your system when Ubuntu 11 is installed. The status message in the Network Manager says that the Wireless is disabled by the hardware switch. Many of you might have this problem when installing a linux, you might be getting the wireless working properly in windows but not in linux.

     i also had the same problem, my laptop Lenovo Z570 had the same issue, i installed ubuntu 11.10, Linux Mint 12 bt all had the same wireless problem, i was really mad.. because i do most of things in linux bt when i have to connect to wireless i had to switch to windows.. ah that was terible....

     Any way i surfed in the net and at last found a solution..... and i got my wireless working in Linux Mint 12... and i`m happy now....

The Solution is :

Enter the following commands in terminal it will enables wireless till next boot

sudo service network-manager stop
sudo rmmod acer_wmi
sudo modprobe acer_wmi
sudo rfkill unblock all
sudo service network-manager start


After this step the status message in the Network Manager will be “Wireless is disabled”
Now Enable wireless from the Network Manager using the following commands

sudo rmmod -f acer_wmi

Wireless networks will be detected and connected.

To make this change permanent use

sudo su
echo "blacklist acer_wmi" >> /etc/modprobe.d/blacklist.conf
exit

Now if everything goes well you will have Wireless enabled on your Laptop
