Security
The DNS-G120 offers 2 types of wireless security - WEP and WPA-PSK.
WEP (Wired Equivalent Privacy) is a method of encrypting data for
wireless communication intended to provide the same level of privacy
as a wired network. 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.
Example:
64-bit hexadecimal keys are exactly 10 characters in length.
(12345678FA is a valid string of 10 characters for 64-bit encryption)
128-bit hexadecimal keys are exactly 26 characters in length.
(456FBCDF123400122225271730 is a valid string of 26 characters for
128-bit encryption)
64-bit ASCII keys are exactly 5 characters in length
(DMODE is a valid string of 5 characters for 64-bit encryption)
128-bit ASCII keys are exactly 13 characters in length
(2002HALOSWIN1 is a valid string of 13 characters for 128-bit encryption)
WPA-PSK (Wi-Fi Protected Access - Pre-Shared Key) is a Wi-Fi
standard that was designed to improve upon the security features of
WEP (Wired Equivalent Privacy).
WPA has Improved data encryption through the Temporal Key Integrity
Protocol (TKIP). TKIP scrambles the keys using a hashing algorithm
and, by adding an integrity-checking feature, ensures that the keys
haven't been tampered with.
The key or passphrase is an alpha-numeric password between 8 and
63 characters long. The passphrase can include symbols (!?*&_) and
spaces. Make sure you enter this key exactly the same as on your
access point or wireless router. You may also enter a hexadecimal
key (using characters 0-9, A-F).
