To find out loaded WiFi driver use the following command line. Open the terminal app and type the following command:
$ lshw -C network
Sample outputs:

  *-network
       description: Wireless interface
       product: Centrino Advanced-N 6205 [Taylor Peak]
       vendor: Intel Corporation
       physical id: 0
       bus info: pci@0000:03:00.0
       logical name: wlp3s0

Look for Wireless interface. From above output it is clear that I am using an “Intel Centrino Advanced-N 6205 [Taylor Peak]”. The configuration section shows driver=iwlwifi as my driver name i.e. iwlwifi driver. To get more info on this driver run the following command:
$ modinfo iwlwifi
