Wifi Protected Setup - ZyXEL Communications P-870HW-51a v2 User Manual

Chapter 7 Wireless LAN
When you select WPA2 or WPA2-PSK in your ZyXEL Device, 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 ZyXEL Device.
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.

7.9.4 WiFi Protected Setup

Your ZyXEL Device 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 between two devices. Both
devices must support WPS (check each device's documentation to make sure).
Depending on the devices you have, you can either press a button (on the device itself, or in its
configuration utility) or enter a PIN (a unique Personal Identification Number that allows one
device to authenticate the other) in each of the two devices. When WPS is activated on a
device, it has two minutes to find another device that also has WPS activated. Then, the two
devices connect and set up a secure network by themselves.
7.9.4.1 Push Button Configuration
WPS Push Button Configuration (PBC) is initiated by pressing a button on each WPS-enabled
device, and allowing them to connect automatically. You do not need to enter any information.
Not every WPS-enabled device has a physical WPS button. Some may have a WPS PBC
button in their configuration utilities instead of or in addition to the physical button.
Take the following steps to set up WPS using the button.
1 Ensure that the two devices you want to set up are within wireless range of one another.
2 Look for a WPS button on each device. If the device does not have one, log into its
configuration utility and locate the button (see the device's User's Guide for how to do
this - for the ZyXEL Device, see
3 Press the button on one of the devices (it doesn't matter which). For the ZyXEL Device
you must press the WPS button for more than three seconds.
4 Within two minutes, press the button on the other device. The registrar sends the network
name (SSID) and security key through an secure connection to the enrollee.
If you need to make sure that WPS worked, check the list of associated wireless clients in the
AP's configuration utility. If you see the wireless client in the list, WPS was successful.
7.9.4.2 PIN Configuration
Each WPS-enabled device has its own PIN (Personal Identification Number). This may either
be static (it cannot be changed) or dynamic (in some devices you can generate a new PIN by
clicking on a button in the configuration interface).
