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)
Alphanumeric (0~9, A~F; for example 01234)

Enter the keys in their fields.
64-bit—Each key contains 10 hexadecimal digits or 5 alphanumeric
characters.
