Transmission Rate

The transmission rate is set according to the speed of your wireless connection. Select the transmission rate from the drop down list, or select 'Auto' to have OpenRG automatically use the fastest possible data transmission rate.

CTS Protection Mode

CTS Protection Mode boosts your gateway's ability to intercept Wireless-G and 802.11b transmissions. Conversely, CTS Protection Mode decreases performance. Leave this feature disabled unless you encounter severe communication difficulties between the gateway and Wireless-G products.

Beacon Interval

A beacon is a packet broadcast by OpenRG to synchronize the wireless network. The Beacon Interval value indicates how often the beacon is sent.

DTIM Interval

The Delivery Traffic Indication Message (DTIM) is a countdown value that informs wireless clients of the next opportunity to receive multicast and broadcast messages. This value ranges between 1 and 16384.

Fragmentation Threshold

Packets that are larger than this threshold are fragmented into multiple packets. Try to increase the fragmentation threshold if you encounter high packet error rates. Do not set the threshold too low, since this can result in reduced networking performance.

RTS Threshold

OpenRG sends Request to Send (RTS) packets to the Wireless client in order to negotiate the dispatching of data. The Wireless client responds with a Clear to Send (CTS) packet, signaling that transmission can commence. In case packets are smaller than the preset threshold, the RTC/CTS mechanism is not active. If you encounter inconsistent data flow, try a minor reduction of the RTS threshold size.
