Chapter 6: Configuring the Wireless-G Broadband Router
The Wireless Tab - Advanced Wireless Settings
Wireless-G 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.
Authentication Type. The default is set to Auto, 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.
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.
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. This should remain disabled unless having severe problems with your Wireless-G
products not being able to transmit to the Router. This function boosts the Router’s ability to catch all 802.11b
and Wireless-G transmissions but will severely decrease performance.
Frame Burst. Enabling this option should provide your network with greater performance, varying upon the
manufacturer of your wireless products.
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.
