wireless card

07:00.0 Network controller: Ralink corp. RT3290 Wireless 802.11n 1T/1R PCIe

Install all the necessary compilation tools at first and download the latest driver from its git repository:(EXAMPLE FOR TL-WN725N)

$$ sudo apt-get install build-essential linux-headers-generic git



$$ mkdir ~/RTL8188EU



$$ cd ~/RTL8188EU



$$ git clone git://github.com/lwfinger/rtl8188eu.git

Afterwards, the driver can be compiled and installed:

Go into the folder and execute following commands.

$$ make

$$ sudo make install

The new kernel module can be loaded via modprobe and can be installed system-wide for automatic loading:

$$ sudo depmod -a

$$ sudo update-initramfs -u

$$ sudo modprobe 8188eu

(Automatic boot:)
To enable the module at each boot add your module to /etc/modules

$$ echo 8188eu >> /etc/modules

Run command

$$ lspci -v

and search for your built-in wifi card...

03:00.0 Network controller: Intel Corporation WiFi Link 5100
Subsystem: Intel Corporation WiFi Link 5100 AGN
Flags: bus master, fast devsel, latency 0, IRQ 47

Now block that card....

$$ sudo echo "blacklist iwlwifi" >> /etc/modprobe.d/blacklist.conf

Now run

$$ lsmod | grep sony

replace sony with company name of your laptop....

Block your laptop (like for sony vaio it is "sony_laptop"....

$$ sudo echo "blacklist sony_laptop" >> /etc/modprobe.d/blacklist.conf

DONE..!!!

Now reboot...
You will be able to run your wifi adapter even if your wireless switch is turned off....!!

I have the pavilion g6. The wireless switch in linux is the f12 key without the fn switch
