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
WPA is also known as “TKIP” (Temporal Key Integrity Protocol).
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 keys
WPA uses encryption keys to encode data. WPA automatically changes the encryption
keys after a certain time interval, thus making the wireless network less vulnerable to
intrusion.
The method by which WPA generates encryption keys depends on the type of
authentication used on the network.
configuring the printer to use WPA
Follow these steps to configure the printer to use WPA:
1. Open the printer's embedded Web server (EWS) (for instructions, click here ).
2. Click the Networking tab.
3. On the Networking page, click the Wireless tab.
