WAP5705 User’s Guide

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.

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 user authentication. 

Usually, you should set up the strongest encryption that every wireless client in the wireless 
network supports. Suppose the wireless network has two wireless clients. Device A only supports 
WEP, and device B supports WEP and WPA-PSK. Therefore, you should set up WEP in the wireless 
network.

Note: It is recommended that wireless networks use WPA-PSK or stronger encryption. 

IEEE 802.1x and WEP encryption are better than none at all, but it is still possible 

for unauthorized devices to figure out the original information pretty quickly.

When you select WPA2-PSK in your WAP5705, you can also select an option (WPA Compatible) 
to support WPA as well. In this case, if some wireless clients support WPA and some support WPA2, 
you should set up WPA2-PSK (depending on the type of wireless network login) and select the 
WPA Compatible option in the WAP5705.

Many types of encryption use a key to protect the information in the wireless network. The longer 
the key, the stronger the encryption. Every wireless client in the wireless network must have the 
same key.

WiFi Protected Setup (WPS) is an industry standard specification, defined by the WiFi Alliance. WPS 
allows you to quickly set up a wireless network with strong security, without having to configure 
security settings manually. Depending on the devices in your network, you can either press a 
button (on the device itself, or in its configuration utility) or enter a PIN (Personal Identification 
Number) in the devices. Then, they connect and set up a secure network by themselves. See how 
to set up a secure wireless network using WPS in the
