Networker,

There are several ways to make wireless more secure. If you use a radius server for authentication you have several options for increased security. EAP/TLS(client and server have X.509 certificaate, allows secure authentication) EAP/TTLS(only server has X.509 certificate, a bit easier to setup and maintain, also allows secure authentication), PEAP(cisco, server certificates.).
