There are two encryption methods that WPA2 adds: one called Advanced Encryption Standard (AES) and one called Temporal Key Integrity Protocol (TKIP). Both of these allow for stronger encryption, and while the differences between the two aren't that important for our purposes, you should pick one method when you set up your network.
Provides network administrators with a high level of assurance that only authorized users can access the network. Based on the ratified IEEE 802.11i standard, WPA2 provides government grade security by implementing the National Institute of Standards and Technology (NIST) FIPS 140-2 compliant AES encryption algorithm. WPA2 can be enabled in two versions - WPA2 - Personal and WPA2 - Enterprise. WPA2 - Personal protects unauthorized network access by utilizing a set-up password. WPA2 - Enterprise verifies network users through a server. WPA2 is backward compatible with WPA.
