MAC address of an authorized device. Then, they can use that MAC address to use
the wireless network.
User Authentication
You can make every user log in to the wireless network before they can use it.
This is called user authentication. However, every device in the wireless network
has to support IEEE 802.1x to do this.
You need to configure a RADIUS server to set up user names and passwords for
your users.
Unauthorized wireless devices can still see the information that is sent in the
wireless network, even if they cannot use the wireless network. Furthermore,
there are ways for unauthorized wireless users to get a valid user name and
password. Then, they can use that user name and password to use the wireless
network.
Encryption
Wireless networks can use encryption to protect the information that is sent in the
wireless network. Encryption is like a secret code. If you do not know the secret
code, you cannot understand the message.
The types of encryption you can choose depend on the type of authentication.
(See
for information about this.)
For example, if the wireless network has a RADIUS server, you can choose IEEE
802.1x, IEEE 802.1x + WEP, WPA or WPA2. If users do not log in to the
wireless network, you can choose WEP, WPA-PSK, or WPA2-PSK.
Usually, you should set up the strongest encryption that every device in the
wireless network supports. For example, suppose you have a wireless network
with the ZyXEL Device. The ZyXEL Device does not have a local user database,
and you do not have a RADIUS server. Therefore, there is no authentication.
Suppose the wireless network has two devices. Device A only supports WEP, and
device B supports WEP and WPA. Therefore, you should set up WEP in the
wireless network.
