Password keys for wireless networks, better known as WEP keys, are a common method for securing wireless networks. These password keys are usually located on the bottom of the wireless router and labelled as WEP keys; however, if this sticker is missing and the WEP key has not been written down or has been forgotten, it is possible to recover the WEP key if it has previously been entered into the computer, and the computer is running the Windows XP Operating System.
