You can use the MAC address filter to tell the AP which wireless clients are allowed or not allowed to
use the wireless network. If a wireless client is allowed to use the wireless network, it still has to
have the correct settings (SSID, channel, and security). If a wireless client is not allowed to use the
wireless network, it does not matter if it has the correct settings.
This type of security does not protect the information that is sent in the wireless network.
Furthermore, there are ways for unauthorized devices to get the MAC address of an authorized
wireless client. Then, they can use that MAC address 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.

Use this screen to configure the SSID and wireless security of the wireless LAN.
Note: If you are configuring the WAH7130 from a computer connected to the wireless
LAN and you change the WAH7130’s SSID, channel or security settings, you will
lose your wireless connection when you press Apply to confirm. You must then
change the wireless settings of your computer to match the WAH7130’s new
settings.
