this explained everything so simple and easy.....
You can configure WEP or WPA. But you cannot enable both at the same time.
You can configure Access list and also enable WEP or WPA for additional security.
After you enable wireless security features on the router (or access point), you must configure your wireless clients (wireless computers) with matching settings. Your wireless clients will not be able to connect unless you configure matching settings.
Its recommended you enable these wireless security settings from a computer wired to the router (or access point).
Connect a computer to any one of the four LAN ports of the NETGEAR router.
Open an Internet explorer and type the router IP address which would be either http://192.168.0.1
(by default, refer to your product documentation ti determine the default IP address.) in the address bar and press Enter.
The Login window will be prompting for a Username and Password. The default Username is admin and the default Password is password
Click Wireless Settings under Setup menu.
Under Security Options, Select WEP (Wired Equivalent Privacy)
Select Authentication type as Automatic and Encryption Strength as 64-bit (or 128-bit) - You must later configure your wireless computers with the same setting.
Select Key 1 and enter any 10 hexadecimal digits - any combination of 0-9, A-F (26 digits if you selected 128-bit as the encryption strength) and Apply the settings. Please note down these values - You must later configure your wireless computers with the same setting.
