You select a single key for encryption of outbound traffic. The WEP-enabled client must have an identical
key of the same length, in the identical slot (1 – 4) as the Gateway, in order to successfully receive and
decrypt the traffic. Similarly, the client also has a ‘default’ key that it uses to encrypt its transmissions. In
order for the Gateway to receive the client’s data, it must likewise have the identical key of the same
length, in the same slot. For simplicity, a Gateway and its clients need only enter, share, and use the first
key.
The pop-up menu for enabling WEP offers these settings: On - Automatic or On - Manual.
• On - Automatic uses a passphrase to generate encryption keys for you. You enter a passphrase that
you choose in the Passphrase field. The passphrase can be any string of words or numbers.
Note: While clients may also have a passphrase feature, these are vendor-specific and may not necessarily
create the same keys. You can passphrase generate a set of keys on one, and manually enter them on the
other to get around this.
Select the Default Key (#1 – #4). The longer the key, the stronger the encr yption and the more difficult it is
to break the encryption.
• On - Manual allows you to enter your own encryption keys manually. This is a difficult process, but only
needs to be done once. Avoid the temptation to enter all the same characters.
Default Key (#1 – #4): Specifies which key the Router will use to encrypt transmitted traffic. The default is
key #1.
Key (#1 – #4): The encryption keys. You enter keys using hexadecimal digits. For 40/64bit encryption, you
need ten digits; 26 digits for 128bit, and 58 digits for 256bit WEP. Hexadecimal characters are 0 – 9, and
a – f. The longer the key, the stronger the encryption and the more difficult it is to break the encryption.
