CNet Technology CWR-800 - Manual (Page 42)

Authentication Type
The default is set to Auto, which allows either Open System or Shared Key
authentication to be used. For Open System authentication, the sender and the recipient do NOT
use a WEP key for authentication. For Shared Key authentication, the sender and recipient use a
WEP key for authentication. If you want to use only Shared Key authentication, then select Shared
Key.
Transmission Rate
The default setting is Auto. The range is from 1 to 54Mbps. 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 keep the default setting, Auto, to have the Router automatically
use the fastest possible data rate and enable the Auto-Fallback feature. Auto-Fallback will
negotiate the best possible connection speed between the Router and a wireless client.
Beacon Interval
The default value is 100. Enter a value between 1 and 65,535 milliseconds. The
Beacon Interval value indicates the frequency interval of the beacon. A beacon is a packet
broadcast by the Router to synchronize the wireless network.
DTIM Interval
The default value is 3. This value, between 1 and 255 milliseconds, 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
Router has buffered broadcast or multicast messages for associated clients, it sends the next
DTIM with a DTIM Interval value. Its clients hear the beacons and awaken to receive the broadcast
and multicast messages.
RTS Threshold
This value should remain at its default setting of 2347. The range is 0-2347 bytes.
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 Router 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 should remain at its default setting of 2346. The range is
