Wi-Fi Interview Question:

Suppose if you are using WEP (Wired Equivalent Privacy) Password with backtrack then how you crack Wi-Fi network?

The first line of defense of your Wi-Fi network is encryption, which encodes the data transmitted between your PC and your wireless router.
WEP abbreviates for (Wireless Encryption Protocol) it is a less-secure protocol than WPA (Wireless Protected Access). Since WEP is relatively easy to crack, so you have to use the same form on all devices on your network. If you have an older router that supports WEP only you'll be best safest if you use 128-bit bit WEP keys but also check the manufacturer's Web site for a firmware update that will add WPA support.

Two of the most popular programs used for actually cracking the WEP key are Airsnort and Aircrack. Airsnort can be used with the .dump files that Kismet provides; and Aircrack can be use with .cap files that Airodump provides.
