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.
Transmission Rate: The rate of data transmission should be set depending on the speed of your
wireless network. You can select from a range of transmission speeds, or you can select AUTO to
have the 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.
Beacon Interval: The Beacon Interval value indicates the frequency interval of the beacon. Enter a
value between 20 and 1000. A beacon is a packet broadcast by the AP to synchronize the wireless
network. The default value is 100.
Antenna selection: There are 3 types antenna setting for this device. Default setting is Diversity.
RTS Threshold: This value should remain at its default setting of 2346. 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 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.
Fragmentation Threshold: This value specifies the maximum size for a packet before data is
fragmented into multiple packets. It should remain at its default setting of 2346. If you experience
a high packet error rate, you may slightly increase the Fragmentation Threshold. Setting the
Fragmentation Threshold too low may result in poor network performance. Only minor
modifications of this value are recommended.
DTIM Interval: This value indicates the interval of the Delivery Traffic Indication Message (DTIM).
A DTIM field is a countdown field informing clients of the next window for listening to broadcast
and multicast messages. When the Access Point has buffered broadcast or multicast messages for
associated clients, it sends the next DTIM with a DTIM Interval value.
Access Point Clients hear the beacons and awaken to receive the broadcast and multicast
messages.
Turbo mode: Enable this setting can accelerate the transmit data rate up to 40%.
