WEP—Provides standard WEP ciphering (Least Secure)

3Select the type of WPA Key Management:

WPA authentication over 802.1x (More secure, but requires a RADIUS authentication server setup. See WPA note below)

WPA Pre-shared Key (PSK) (see WPA note below)

4Select the Key Type:

Hexadecimal (0~9, A~F; for example, D7 0A 9C 7F E5) Alphanumeric (0~9, A~F; for example 01234)

5Enter the pre-shared key in the space provided if necessary.

WPA Note:

The WPA key management must match the settings on the Authentication Page. When using 802.1x, the access point uses session keys provided during the 802.1x EAP key exchange as the “seed key” for WPA. This is more secure than PSK, since each client starts with a unique session key for all subsequent keys generated. Otherwise, the PSK is used for the “seed key”.

The 802.1x Setup on the Authentication Page should be set as follows:

-If only one Radio is installed, and “WPA pre-shared key (PSK)” is selected on the security page, then the 802.1x setup can be either “Disabled” or “Supported” on the Authentication Page.

-If only one Radio is installed and “WPA authentication over 802.1x” is selected on the security page, then 802.1x setup must be either “Supported” or “Required” on the Authentication Page.

-If two Radios are installed and WPA is being used with “WPA authentication over 802.1x” selected for both radios’ WPA key management, then set the 802.1x setup to “Required” on the Authentication Page.

-If one radio’s security is set to “WPA pre-shared key (PSK)” for WPA key management and the other is set to “WPA authentication over 802.1x”, then the 802.1x Setup must be set to “Supported” on the Authentication Page instead.

WEP Configuration

WEP encryption is based on the use of security keys and the popular RC4 encryption algorithm.

At least one transmit key must be defined in the WEP Configuration. Wireless devices without a valid WEP key will be excluded from network traffic.
