WPA and WPA2 require the user to provide a secure key to connect. When the key is authenticated, the data sent between the computer or the device and the access point is encrypted. is more secure than WPA,WPA2 authentication. Almost all new wireless adapters support WPA and WPA2, but some older wireless adapters are not supported. It is recommended that the home network adopt this mode.
