Description
Authentication Type
Open System: Open System authentication is not required to be successful wh
ile 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
his 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, you may slightly increases the “Fragment Threshold” value
within the value range of 256 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 fram
e.
After receiving an RT 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.
