WiFi Protected Access 2 (WPA2) is the permanent replacement for WPA and WEP.
WiFi Protected Access 2 (WPA2) is the permanent replacement for WPA and WEP. WPA2 which is also known as 802.11i uses stronger cryptography than WPA. The final WiFi Alliance requires all devices carrying its WI-FI CERTIFIED logo to meet WPA2 standards, including the use of the Counter Mode with Cipher Blocking Chaining Message Authentication Protocol (CCMP). CCMP is based on AES encryption which is much stronger than the older TKIP protocol and CCMP should be used instead of TKIP.
Although WPA2 provides significant security improvements over previous wireless encryption techniques, some enterprises need stronger security. So that is why sometimes you will see WPA2 enterprise instead of WPA2 personal.
When users are using the personal mode that means they operate with a Pre-Shared Key (PSK) protocol. When using (PSK) mode, users access the wireless network anonymously with a pre-shared key passphrase. This doesn't provide authentication but rather just authorization by means of something you know like the password.
Use WiFi Scanner to see what security protocol suite your network supports and what others around you are using. Use either the SSID list or the Filter Tree as seen below.
