wireless encryption. It is a symmetric 128-bit block encryption method
that works simultaneously on multiple network layers.
• Wireless Network Key - This option becomes configurable when you
select the WPA-Personal authentication mode. Key in 8 to 63 characters
in this field.
Note: The characters can also consist of 64 hexadecimal digits.
• Wireless Network Key (WEP) - This option becomes configurable when
you select WEP in the Data encryption field. 64-bit WEP key uses 5 ASCII
characters (10 hexadecimal digits). 128-bit WEP key uses 13 ASCII (26
hexadecimal digits).
• Key Format - Allows you to select the key format.
• Passphrase -
• Passphrase - Passphrase - This field generates the WEP keys (Key 1 - Key 4). The
passphrase can consists of a sentence, a phrase, or a sequence of alpha-
numeric characters .
• Key Length - Allows you to select the key length. For 64-bit encryption,
each key consists of 10 hexadecimal digits or 5 ASCII characters. For 128-
bit encryption, each key consists of 26 hexadecimal digits or 13 ASCII
characters.
• Select one as your Default
Key - Allows you to select
one of the four WEP Keys as
the default key.
Configuration - Advanced
This Advanced page is intended
for experienced users to set up
additional parameters for the WLAN adapter. We recommend that you keep the
default values.
• RTS Threshold (0-2347) - The Request to Send/Clear to Send (RTS/CTS)
function is used to minimize collisions among wireless stations. When RTS/
CTS is enabled, the router refrains from sending a data frame until another
RTS/CTS handshake is completed. To enable RTS/CTS, set a specific packet
size threshold. The default value (2347) is recommended.
• Fragmentation Threshold (256-2346) - Fragmentation Threshold (256-2346) - Fragmentation is used to divide
802.11 frames into smaller pieces (fragments) that are sent separately to the
destination. To enable fragmentation, set a specific packet size threshold.
If there is an excessive number of collisions on the WLAN, experiment
with different fragmentation values to increase the reliability of frame
transmissions. The default value (2346) is recommended for normal use.
• Preamble Mode - Preamble Mode - Select the preamble mode as Auto (default), Long or
Short.
