Wired Equivalent Privacy (WEP)
is a less secure, but more
widely adopted wireless security protocol. Depending on the security
level (64- or 128-bit), the user will be asked to input a 10- or
26-character hex key. A hex key is a combination of letters, a–f,
and numbers, 0–9.
Wireless Protected Access (WPA)
is the new standard in
the wireless security. However, not all wireless cards and adapters
support this technology. Please 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
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.
