If the AP or the wireless clients do not support WPA2, just use WPA or WPA-PSK depending 
on whether you have an external RADIUS server or not.
Select WEP only when the AP and/or wireless clients do not support WPA or WPA2. WEP is 
less secure than WPA or WPA2.
3.4  WiFi Protected Setup
Your NWD271N 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.
3.4.1  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.
Ensure that the two devices you want to set up are within wireless range of one another. 
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 NWD271N, see 
Press the button on one of the devices (it doesn’t matter which).
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.
3.4.2  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).
