Wi-Fi Protected Access (WPA) Wi-Fi Protected Access (WPA) provides security by doing the following: q Encrypting data sent over radio waves from one wireless device to another wireless device q 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.
