On this screen you can access the Advanced Wireless features, including Authentication Type, Basic Data Rates,
Control Tx Rates, Beacon Interval, DTIM Interval, RTS Threshold, and Fragmentation Threshold.
•
Authentication Type. The default is set to Auto (default), which allows either Open System or Shared Key
authentication to be used. For Open System authentication, the sender and the recipient do not use a WEP
key for authentication but can use WEP for data encryption. If you want to allow on Open System
authentication, then select
Open System
. For Shared Key authentication, the sender and recipient use a WEP
key for both authentication and data encryption. If you want to use only Shared Key authentication, then
select
Shared Key
. It is recommended that this option be left in the default (Auto) mode, because some
clients cannot be configured for Shared Key.
•
Control Tx Rates. The default transmission rate 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 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.
•
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. 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 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.
