WPA2 Enterprise with AES is the best choice for secure wireless encryption with advanced encryption methods and support for central authentication services like RADIUS and directory services. WPA2 Enterprise uses IEEE 802.1X to provide the authentication framework for wireless clients. AES is an encryption standard that is more secure than TKIP, which was introduced as a temporary solution in WPA to replace WEP without requiring new hardware. WPA Personal with AES, despite also using AES, does not provide the necessary framework for central authentication services. WEP is considered insecure due to known vulnerabilities that make it susceptible to hacking attempts.
