Wireless-B Broadband Router

The Wireless Tab - Advanced Wireless Settings

This tab is used to set up the Router’s advanced wireless functions. These settings should only be adjusted by an expert administrator as incorrect settings can reduce wireless performance.

Basic Rate. The Basic Rate setting is not actually one rate of transmission but a series of rates, advertising to the other wireless points in your network at what rates the Router can transmit. At the default setting, the Router will advertise that it will Automatically select the best rate for transmission. Other options of rates to advertise are 1-2Mbps, for use with older wireless technology, and All, when you wish to make all rates advertised. The Basic Rate is not the rate transmitted; that is the Transmission Rate.

Control Tx Rates. The default transmission rate 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 Gateway automatically use the fastest possible data rate and enable the Auto-Fallback feature. Auto-Fallback will negotiate the best possible connection speed between the Gateway and a wireless client.

Preamble Type. The preamble defines the length of the CRC block for communication between the Router and the

roaming Network Card. (High network traffic areas should use the shorter preamble type.) Select the appropriate

 

preamble type, Long Preamble(default) or Short Preamble.

 

Authentication Type. The default is set to Auto (default), which allows either Open System or Shared Key

 

authentication to be used. With Open System authentication, the sender and the recipient do NOT use a WEP key

 

for authentication. With Shared Key authentication, the sender and recipient use a WEP key for authentication.

 

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. This value, between 1 and 16384, 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. The default value is 1.

 

Fragmentation Threshold. This value 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 increase the Fragmentation

 

Threshold. Setting the Fragmentation Threshold too low may result in poor network performance. Only minor

 

reduction of the default value is recommended. In most cases, it should remain at its default value of 2346.
