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.
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 wireless client in the wireless
network supports. For example, suppose the AP does not have a local user database, and you do
not have a RADIUS server. Therefore, there is no user authentication. Suppose the wireless network
has two wireless clients. Device A only supports WEP, and device B supports WEP and WPA.
Therefore, you should set up Static WEP in the wireless network.
network supports. For example, suppose the AP does not have a local user database, and you do
not have a RADIUS server. Therefore, there is no user authentication. Suppose the wireless network
has two wireless clients. 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. 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.
Note: It is not possible to use WPA-PSK, WPA or stronger encryption with a local user
database. In this case, it is better to set up stronger encryption with no
authentication than to set up weaker encryption with the local user database.
When you select WPA2 or WPA2-PSK in your NBG4615, 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 or WPA2 (depending on the type of wireless network
login) and select the WPA Compatible option in the NBG4615.

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.

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

WDS
Wireless Distribution System or WDS security is used between bridged APs. It is independent of the
security between the wired networks and their respective APs. If you do not enable WDS security,
traffic between APs is not encrypted. When WDS security is enabled, both APs must use the same
pre-shared key.
