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.

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
in the wireless network.

Note: It is recommended that wireless networks use
encryption are better than none at all, but it is still possible for unauthorized devices to
figure out the original information pretty quickly.

WPA as well. In this case, if some wireless clients support WPA and some support WPA2, you should set up
and select the
WPA2- PSK
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.
7.3.1.3 WPS
Wi-Fi Protected Setup (WPS) is an industry standard specification, defined by the Wi-Fi 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 enter a PIN (Personal Identification Number) in the devices. Then, they connect and set
up a secure network by themselves.
