Advanced Wireless
Wireless-G Settings
This tab is used to set up the Gateway's advanced wireless functions. These settings should only be adjusted by
an expert administrator as incorrect settings can reduce wireless performance.
• Basic Rate Set. The Basic Rate Set is a series of rates at which the Gateway can transmit. (If you want to
specify the Gateway's actual rate of data transmission, configure the Transmission Rate setting.) The Gateway
will advertise its Basic Rate Set to the other wireless devices in your network, so they know which rates will
be supported. The Gateway will also advertise that it will automatically select the best rate for transmission.
In most cases, you should keep the default setting, Default (1-2-5.5-11). Other options are 1-2Mbps, for use
with older wireless technology, and All, when the Gateway can transmit at all wireless rates.
• 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 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. The default 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 Gateway in an environment with heavy 802.11b
traffic, the CTS Protection Mode will be used. This function boosts the Gateway's ability to catch all Wireless-
G transmissions but will severely decrease performance.
• Beacon Interval. A beacon is a packet broadcast by the Gateway to synchronize the wireless network.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 Gateway 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 Gateway 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
