29 How to Make Your WLAN More Secure All your network clients MUST share the same wireless sett ings as your router to be able to communicat e. The router offers 8 types of security modes: WEP Short for Wired Equivalent Privacy, WEP is a security protocol basing on a sec ret key to encryp t data pac kets befo re they a re trans mitted.
30 WPA2 Personal W PA2 Personal mode implements the full IEEE 802.11i standard with a shared network password for clients and access point s. The only interaction is between the router and the client , therefore, a RADIUS server is NOT required. WPA2 Enterprise W PA2 Ent erprise mode implements the full IEEE 802.
31 The subsequent sections illustrate how t o configure each securi ty mode. Begi n with follo wing the two c ommon preliminary steps shown below to select the most appropriat e securi ty mod e to protec t your wi reless communications.
