Securing your Wi-Fi
Here are a few different ways to maximize the security of your wireless
network and protect your data from unwanted intrusion. This section
is intended for the home, home office, and small office user. At the
time of publication, three encryption methods are available.

WEP (Wired Equivalent Privacy)
WEP (Wired Equivalent Privacy) 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.
