Are you locked out of your network? have you ever wanted to fix the whole things rather than have to rebuild. We have the answer:

Instructions

1. Step 1

   Locate the wireless network that you want to connect to. The information on the network should identify the type of hardware used, such as the brand of the router. You can normally get this information by right-clicking on the name of the network and selecting “Network Properties.” Make note of this information. If you do not have a way of detecting wireless networks to get the information, use software programs such as Kismet and Netstumbler (see resoucres below).

2. Step 2

   Attempt to access the system using default login information. The most common login information is “admin/admin” or “admin/password” for the username and password combination. As silly as that may sound, people actually use these combinations. If these do not work, try using the default login information that the manufacturer programed into the hardware. There is a link in the Resources section to a list of these default log ins. Should these not give you access to the network, continue to the next Step.

3. Step 3

   Obtain a copy of the Aircracks software package. This software consists of four different utilities. Together, these four utilities are all that you’ll need to hack into any wireless network.

4. Step 4

   Use Airodump to collect data packets that the network sends out. If you had obtained a copy of Kismet software in Step 1, this program will also collect packets for you. The network will sometimes use the same IV (Initialization Vector) more than once, known as a collision, so by analyzing several thousand packets, you can identify what these repeated vectors are.

5. Step 5

   Continue collecting data packets from the wireless network The system will periodically send out what is known as an Address Resolution Protocol (ARP) in one of these packets. This is essentially a check to see if the connection is still online. It contains the encryption key that is needed to gain access to the system. However, you will need to collect a large number of data packets before you are lucky enough to capture this one.

6. Step 6

   Open the Aircrack utility and use it to scan the data packets that you have captured. The Aircrack utility will scan these files until it finds the ARP packet with the encryption key. It will then work with the Airdecap program to decrypt the contents of the packet and gain access to the wireless network.
