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.
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 Wireless 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 Wireless 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.
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:
1 Under Encryption, select Enable.
2 Under WEP Configuration, select the Key Size.
The access point supports shared key encryption with key lengths of 64-bits,
128-bits, or 152-bits.
3 Select the Key Type.
Hexadecimal (0~9, A~F; for example, D7 0A 9C 7F E5)
ASCII (0~9, A~F; for example 01234)
3Com Passphrase(a string, described below)
4 Enter the keys in their fields.
64-bit—Each key contains 10 hexadecimal digits or 5 alphanumeric
characters.
128-bit—Each key contains 26 hexadecimal digits or 13 alphanumeric
characters.
