Securing your Wi-Fi Network
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.

Wired Equivalent Privacy (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.
1 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.
