Field Description
Authentication
Type Open System: Open System authentication is not
required to be successful while a client may decline to
authenticate with any particular other client.
Shared Key: Shared Key is only available if the WEP
option is implemented. Shared Key authentication
supports authentication of clients as either a member
of those who know a shared secret key or a member of
those who do not. IEEE 802.11 Shared Key
authentication accomplishes this without the need to
transmit the secret key in clear. Requiring the use of
the WEP privacy mechanism.
Auto: Auto is the default authentication algorithm. It
will change its authentication type automatically to fulfill
client’s requirement.
Fragment
Threshold When transmitting a packet over a network medium,
sometimes the packet is broken into several segments,
if the size of packet exceeds that allowed by the
network medium.
The Fragmentation Threshold defines the number of
bytes used for the fragmentation boundary for directed
messages.
This value should remain at its default setting of 2346.
It specifies the maximum size for a packet before data
is fragmented into multiple packets. If you experience a
high packet error rate, you may slightly increases the
“Fragment Threshold” value within the value range of
256 to 2346. Setting this value too low may result in
poor network performance. Only minor modifications of
this value are recommended.
RTS Threshold This value should remain at its default setting of 2347.
Should you encounter inconsistent data flow, only
minor modifications are recommended. If a network
packet is smaller than the preset “RTS threshold” size,
the RTS/CTS mechanism will not be enabled. The
ADSL modem (or AP) sends Request to Send (RTS)
frames to a particular receiving station and negotiates
the sending of a data frame. After receiving an RTS,
the wireless station responds with a Clear to Send
(CTS) frame to acknowledge the right to begin
transmission.
Beacon Interval The Beacon Interval value indicates the frequency
interval of the beacon. Enter a value between 20 and
1024. A beacon is a packet broadcast by the ADSL
modem (or AP) to synchronize the wireless network.
The default is 100.
Data Rate The rate of data transmission should be set depending
on the speed of your wireless network. You should
select from a range of transmission speeds, or you can
select Auto to have the ADSL modem (or AP)
automatically use the fastest possible data rate and
enable the Auto-Fallback feature. Auto-Fallback will
negotiate the best possible connection speed between
the AP and a wireless client. The default setting is
Auto.
Preamble Type Specify the Preamble type is short preamble or long
preamble
