There are a lot of free tools available online to get easy access to WiFi networks, intended to help the network admins and the programmers working on the WiFi systems. Most of the times people prefer to use wireless network LAN which is much easier and cost effective.
It has been observed that the neighborhood WiFi hot-spots are visible on user’s devices, however one can get access only by cracking the password for the purpose of using free internet.
Vulnerability in wireless LAN is due primarily to poor configuration and poor encryption. Poor configuration includes the case of weak password. Poor encryption is dangerous, as it is related to the 2 security protocols WEP and WPA.
The tools used to hack the network are used either for:
- the purpose of sniffing the network: as is the case of network admins and
- cracking the password: used to rectify trouble shooting, by the people who want to use the internet free of cost.
So, here are the the tools for cracking wireless passwords.
The best free Wireless hacking passwords
The most popular wireless password cracking tool, it attacks 802.11a/b/g WEP and WPA. The manufacturers of this tool also provide tutorials for installation of the tool and its usage for cracking the password. Prior to using this tool, it is essential to confirm that the wireless card can inject packets, as this is basis of WEP attack.

This is a network protocol analyzer. Again, this software is good for the network admins, keeping a check on the traffic. Basic requirement are that the user should have a good knowledge of the network protocol, only then they can use this tool. The user must also install Wincap which comes along with it.

This tool is an automated dictionary attack tool for WPA-PSK. CoWPatty is simple to use however it is slow. The tool uses the password dictionary for cracking each word contained in the dictionary by using the SSID. DOWNLOAD LINK :http://sourceforge.net/projects/cowpatty/
6) Gerix Wifi cracker:
A graphical user interface for aircrack-ng and pyrit.

This is an open source Linux tool for breaking 802.11 WEP keys. While working with this tool a WLAN card is required, and basically the tool attacks the working key using the dictionary.

This is again a network analyzer tool working only on Windows OS. This tool captures and analyzes the network traffic. The tool can be also used for trouble shooting.
10) CommView for WiFi
This is for wireless monitoring and protocol analysis. Captured packets can be decoded by user-defined WEP or WPA keys. This again is mainly used to monitor the WiFi traffic by professional programmers, protocol admins and even at homes.

Most of these tools are free; some of them are for protocol analyzers to monitor the trouble shooting whereas others are for cracking the passwords for unauthorized internet access.
For network admins and professional programmers, these tools should be more helpful for understanding the cracking of passwords and hence helping them professionally. Such tools are also used by cyber criminals and terrorists to get easy access for free usage of internet anonymously.
