4.2.7 Wi-Fi Protected Access (WPA)
Wi-Fi Protected Access (WPA) provides security by doing the following:
• Encrypting data sent over radio waves from one wireless device to another
wireless device
• Controlling access to network resources through authentication protocols
Only devices that share the same WPA settings as the printer will be able to
communicate with the printer.
For example, if the printer's network uses WPA, only devices that have the same
WPA settings as the printer will be able to use the printer.
WPA provides better security than
WEP .
WPA is a network feature
WPA is an optional wireless network feature. Not all wireless networks use WPA.
Configure the printer for WPA only if the printer's network uses WPA. The printer's
WPA settings must match the network's settings.
If the printer's network does not use WPA, then do not configure the printer to use
WPA.
If you do not know if your network uses WPA, consult the configuration utility for
your computer's NIC card or your network's Wireless Access Point (WAP) .
Encryption
WPA uses encryption keys to encode data.
The printer supports two types of WPA encryption: TKIP and AES.
For more information about TKIP and AES, see the
authentication and encryption
page .
