Passphrase - This is another common method and similar to the 3Com
Encryption string. In 64 bit WEP, the passphrase will generate 4
different keys. However, in 128 bit WEP, this method only generates 1
key which is replicated for all 4 keys. The passphrase can be up to 31
characters long and may contain any alphanumeric characters.

If you encounter any difficulty when you enable WEP ensure that you
check that each key on your wireless computer is exactly the same as
each key on your Gateway. In other words, Key number 1 on the Wireless
computer must have the same Hex number as Key number 1 on the
Gateway, Key 2 on the Wireless computer must match Key 2 on the
Gateway and so on.

The Active Transmit Key selects which of the 4 Keys the Gateway uses
when it transmits. You can change the selected key periodically to
increase the security of your network.

use both encryption and you specify only certain wireless computers can
connect to the Gateway. By default, any wireless computer that has the
