[Fixed] Intel wireless N 6230 on Ubuntu

I had issue with the Intel wireless card, and it kept on dropping connection when I am working online, thus I look for solution online.

Then I found this: http://ubuntuforums.org/showthread.php?t=2012228

To put it in short:

1. Open terminal in Ubuntu
2. Type:

   gksudo gedit /etc/pm/power.d/wireless

3. Then enter these inside gedit: 

   #!/bin/sh

   /sbin/iwconfig wlan0 power off

   exit0

4. Save and close gedit.
5. Run the following commands:

   echo "options iwlwifi 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf
   sudo modprobe -rfv iwlwifi
   sudo modprobe -v iwlwifi
   sudo reboot

    If you still having issue with the wifi, 
   navigate to /etc/modprobe.d, 
   then sudo gedit iwlwifi.conf 
   Edit the line to:
   options iwlwifi 11n_disable=1 wd_disable=1 bt_coex_active=N  

Convert arguments into array in javascript

Let see this senario:

var func = function(){
      arguments.push('foo');
}

Then you run func('a', 'b', 'c'), you will get Object has no method 'push'.

To enable your arguments being treated as array,

var func = function(){
        var arry = Array.prototype.slice.call(arguments);
        arry.push('foo');
}

You would able to use the push method, because you have converted the arguments into array.
