Wireless-G Broadband Router with SRX400

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.

Advanced Wireless

Basic Rate Set. The Basic Rate is not the actual rate of data transmission; it is a series of rates at which the Router can transmit. (If you want to specify the Router’s rate of data transmission, configure the Transmission Rate setting.) The Router will advertise its Basic Rate Set to the other wireless devices in your network, so they know which rates will be supported. The Router will also advertise that it will automatically select the best rate for transmission. In most cases, you should keep the default setting, Basic Rate Set #2, which includes higher data rates for higher performance. If your wireless computers or other clients cannot associate with the Router, select Basic Rate Set #1, a set of data rates specified by the 802.11b standard.

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 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. The default value is Auto.

CTS Protection Mode. CTS (Clear-To-Send) Protection Mode should remain set to its default, Auto, so when your Wireless-G products are not able to transmit to the Router in an environment with heavy 802.11b traffic, the CTS Protection Mode will be used. This function boosts the Router’s ability to catch all Wireless-G transmissions but will severely decrease performance.

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 255, 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.

cts (clear to send): a signal sent by a wireless device, signifying that it is ready to receive data

beacon interval: data transmitted on your wireless network that keeps the network synchronized

dtim: a message included in data packets that can increase wireless efficiency.

fragmentation: breaking a packet into smaller units when transmitting over a network medium that cannot support the original size of the packet.
