Wireless-G VPN 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
advanced user as incorrect settings can reduce wireless performance.
Advanced Wireless
Authentication Type. The default is set to Auto, which allows either Open System or Shared Key authentication
to be used. Select the appropriate authentication type for your network. For Open System authentication, the
sender and the recipient do NOT use a WEP key for authentication. For Shared Key authentication, the sender and
recipient use a WEP key for authentication.
Basic Data Rates. Select 1-2 Mbps, All (1-2-5.5-6-11-24), or Default (1-2-5.5-11), from the drop-down
menu. The Basic Data Rates 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 Data 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). Other options are 1-2Mbps, for use with older wireless technology, and All, when the
Router can transmit at all wireless rates (1-2Mbps, 5.5Mbps, 6Mbps, 11Mbps, 24Mbps). 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
Control Tx Rate setting.
Control Tx Rates.The default value 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 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.
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. The default value is 3.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.
RTS Threshold. The RTS Threshold value should remain at its default value of 2347. Should you encounter
inconsistent data flow, only minor reduction of the default value, 2347, is recommended. If a network packet is
