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.

6 .3 .4   Enc ryp tio n

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.

For example, if users do not log in to the wireless network, you can choose no encryption, WEP, WPA-PSK, 
or WPA2-PSK.

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 WPA2-PSK. Therefore, you should set up WEP in the wireless network.

Note: It is recommended that wireless networks use WPA2-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.

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.

6 .3 .5   WPS

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 

Section 5.3 on page 46

Use this screen to enable the Wireless LAN, enter the SSID and select the wireless security mode.

Note: If you are configuring the NBG-418N v2 from a computer connected to the wireless LAN 

and you change the NBG-418N v2’s SSID, channel or security settings, you will lose your 
wireless connection when you press 

A p p ly

 to confirm. You must then change the 

wireless settings of your computer to match the NBG-418N v2’s new settings.
