When you select 64-bit or 128-bit WEP key, you have to enter WEP keys to encrypt data.
You can generate the key by yourself. You can enter up to four WEP keys and select one of
them as a default key. The AP can receive any packet encrypted by one of the four keys.
Authentication Type:
There are two authentication types: "Open System" and "Shared Key". Both
AP and wireless client must be configured with the same authentication type.
Key Length:
You can select the WEP key length for encryption, 64-bit or 128-bit. The larger
the key will be the higher level of security is used, but the throughput will be lower.
