Wifi Protected Setup - ZyXEL Communications P-2812HNU-51c User Manual

The types of encryption you can choose depend on the type of authentication.

For example, if the wireless network has a RADIUS server, you can choose WPA
or WPA2. If users do not log in to the wireless network, you can choose no
encryption, Static 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 P-2812HNU-51c 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
Static WEP in the wireless network.
Note: It is recommended that wireless networks use WPA-PSK, WPA, or stronger
encryption. The other types of encryption are better than none at all, but it is still
possible for unauthorized wireless devices to figure out the original information
pretty quickly.
When you select WPA2 or WPA2-PSK in your P-2812HNU-51c, you can also
select an option (WPA compatible) to support WPA as well. In this case, if some
of the devices support WPA and some support WPA2, you should set up WPA2-
PSK or WPA2 (depending on the type of wireless network login) and select the
WPA compatible option in the P-2812HNU-51c.
Many types of encryption use a key to protect the information in the wireless
network. The longer the key, the stronger the encryption. Every device in the
wireless network must have the same key.

7.10.4 WiFi Protected Setup

Your P-2812HNU-51c supports WiFi Protected Setup (WPS), which is an easy way
to set up a secure wireless network. 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. Each WPS connection works
