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 Wireless 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 Wireless 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 Wireless Setup must be either “Supported” or “Required” on the Authentication Page.

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.

The key selected as the transmit key index is used by the access point for all transmissions. Other keys defined can be used by the access point for decrypting station communications. When enabling 802.1x security with dynamic session keys, key index 4 is reserved for the 802.1x client session key. Therefore, when 802.1x clients are in the network, the access point should not be configured to use key index 4 as the transmit key index.

To configure WEP encryption:

1Under Encryption, select Enable.

2Under WEP Configuration, select the Key Size.

The access point supports shared key encryption with key lengths of 64-bits, 128-bits, or 152-bits.

3Select the Key Type.

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

3Com Passphrase(a string, described below)

4Enter the keys in their fields.

64-bit—Each key contains 10 hexadecimal digits or 5 alphanumeric characters.
