25D-Link DWA-111 User Manual
Section 4 - Security
Wireless Security
This section will show you the different levels of security you can use to protect your data from intruders. The
DWA-111 offers the following types of security:
• WPA2 (Wi-Fi Protected Access 2) • WPA2-PSK (Pre-Shared Key)
• WPA (Wi-Fi Protected Access) • WPA-PSK (Pre-Shared Key)
• WEP (Wired Equivalent Privacy)
What is WEP?
WEP stands for Wired Equivalent Privacy. It is based on the IEEE 802.11 standard and uses the RC4 encryption algorithm. WEP
provides security by encrypting data over your wireless network so that it is protected as it is transmitted from one wireless device
to another.
To gain access to a WEP network, you must know the key. The key is a string of characters that you create. When using WEP, you
must determine the level of encryption. The type of encryption determines the key length. 128-bit encryption requires a longer key
than 64-bit encryption. Keys are defined by entering in a string in HEX (hexadecimal - using characters 0-9, A-F) or ASCII (American
Standard Code for Information Interchange – alphanumeric characters) format. ASCII format is provided so you can enter a string
that is easier to remember. The ASCII string is converted to HEX for use over the network. Four keys can be defined so that you can
change keys easily.
