check your wireless adapter’s user manual to check if it supports WPA. Instead
of a hex key, WPA uses only passphrases, which are much easier to remember.
The following section, intended for the home, home-office, and small-office user,
presents a few different ways to maximize the security of your wireless network.
At the time of publication, four encryption methods are available:

WEP
WEP is a common protocol that adds security to all Wi-Fi-compliant wireless
products. WEP gives wireless networks the equivalent level of privacy protection
as a comparable wired network.
64-Bit WEP
64-bit WEP was first introduced with 64-bit encryption, which includes a key
length of 40 bits plus 24 additional bits of system-generated data (64 bits total).
Some hardware manufacturers refer to 64-bit as 40-bit encryption. Shortly after
the technology was introduced, researchers found that 64-bit encryption was too
easy to decode.
128-Bit Encryption
As a result of 64-bit WEP’s potential security weaknesses, a more secure
method of 128-bit encryption was developed. 128-bit encryption includes a key
