ADSL Router User Manual

For WPA-PSK/WPA2-PSK/Mixed WPA-PSK

WiFi-Protected Access:
WPA-PSK is useful for small places such as
home environment without having
authentication servers. It allows the use of
manually-entered keys or passwords and is
designed to be easy to set up for home users.

Format:

Choose the typing method of encryption key.
You have to click either Hexadecimal digits
or ASCII characters and type the keys on
the field of Pre-Share Key.

Pre-Share Key:
Please type with the key between 8 and 63
characters, or 64 hexadecimal digits. Only
the devices with a matching key that you set
here can join this network.

WPA Group Rekey Interval:
Type in the time for the WAP group rekey
interval. The unit is second.

Data Encryption (WPA):

Select the data encryption for the WPA
mode. There are three types that you can
choose, TKIP, AES, TKIP+AES.

TKIP takes the original master key only
as a starting point and derives its
encryption keys mathematically from this
master key. Then it regularly changes and
rotates the encryption keys so that the
same encryption key will be never used
twice.

AES provides security between client
workstations operating in ad hoc mode. It
uses a mathematical ciphering algorithm
that employs variable key sizes of 128, 192
or 256 bits.

TKIP+AES combines the features and
functions of TKIP and AES.

After finished settings, click Apply for
activation.
