Wireless-G Access Point

Advanced Wireless

Before making any changes to the Wireless tab, please check your wireless settings on other systems, as these

changes will alter the effectiveness of the Access Point. In most cases, these settings do not need to be changed.

Authentication Type. The default is set to Auto, where it auto-detects for Shared Key or Open System. Shared

Key is when both the sender and the recipient share a WEP key for authentication. Open Key is when the sender

and the recipient do not share a WEP key for authentication. All points on your network must use the same

authentication type.

Transmission Rates. The default setting 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 you can keep the default setting, Auto, to have the Access Point automatically use the fastest possible

data rate and enable the Auto-Fallback feature. Auto-Fallback will negotiate the best possible connection speed

between the Access Point and a wireless client.

CTS Protection Mode. CTS (Clear-To-Send) Protection Mode should remain disabled unless you are having

severe problems with your Wireless-G products not being able to transmit to the Access Point in an environment

with heavy 802.11b traffic. This function boosts the Access Point's ability to catch all Wireless-G transmissions

but will severely decrease performance.

Basic Rate. The Basic Rate setting is not actually one rate of transmission but a series of rates, advertising to the

other wireless devices in your network at what rates the Access Point can transmit. At the Default setting, the

Access Point 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.

Antenna Selection. This selection is for choosing which antenna transmits data, left or right. By default, the

Diversity antenna selection, used to increase reception, is chosen.

Frame Burst. Enabling this option should provide your network with greater performance, depending on the

manufacturer of your wireless products. If you are not sure how to use this option, keep the default, Off.

Beacon Interval. This value indicates the frequency interval of the beacon. A beacon is a packet broadcast by

the Access Point to keep the network synchronized. A beacon includes the wireless LAN service area, the AP

address, the Broadcast destination addresses, a time stamp, Delivery Traffic Indicator Maps, and the Traffic

Indicator Message (TIM).

RTS Threshold. This setting determines how large a packet can be before the Access Point coordinates

transmission and reception to ensure efficient communication. This value should remain at its default setting of

2,346. Should you encounter inconsistent data flow, only minor modifications are recommended.
