Connecting to a Secure Wi-Fi ® network
If you choose to connect to a secure network,
determine the type of security (WPA/WPA2 or WEP)
and use the appropriate field in the dialog box.
Wireless 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.
Wi-Fi Protected Access ® (WPa ® /WPA2 ® ) is the new standard
in wireless security. Instead of a hex key, WPA/WPA2 uses only
passphrases, which are much easier to remember. The passphrase
is 8–63 characters and can consist of alphabet letters and numbers.
