Compact 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.
Advanced Wireless
Wireless-G Settings
Authentication Type. The default is set to Auto (Default), 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.
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 (Default) 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
(Default).
Basic Rate. The Basic Rate setting is not actually one rate of transmission but a series of rates at which the
Router can transmit. The Router will advertise its Basic Rate to the other wireless devices in your network, so
they know which rates will be used. The Router will also advertise that it will automatically select the best rate
for transmission. The default setting is Default, when the Router can transmit at all standard wireless rates
(1-2Mbps, 5.5Mbps, 11Mbps, 18Mbps, and 24Mbps). Other options are 1-2Mbps, for use with older wireless
technology, and All, when the Router can transmit at all wireless rates. The Basic Rate is not the actual rate of
data transmission. If you want to specify the Router's rate of data transmission, configure the Transmission Rate
setting.
CTS Protection Mode. CTS (Clear-To-Send) Protection Mode should be set to Auto (Default). The Router will
automatically use CTS Protection Mode when your Wireless-G products are experiencing severe problems and
are not able to transmit to the Router in an environment with heavy 802.11b traffic. This function boosts the
Router's ability to catch all Wireless-G transmissions but will severely decrease performance.
DTIM Interval. This value 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.
