“Super-A with Static/Dynamic Turbo”.
4.2.7.8 Rate Control
Select here to change the Data Rate for the radio. Lower data rate sometimes provide
longer distance. In most cases, however, we recommend to keep the setting at “Best”.
4.2.7.9 Ack TimeOut
When a packet is sent out from one wireless station to the other, it will waits for an
Acknowledgement frame from the remote station. The station will only wait for a certain
amount of time, this time is called the ACK timeout. If the ACK is NOT received within that
timeout period then the packet will be re-transmitted resulting in reduced throughput. If
the ACK setting is too high, then throughput will be lost due to waiting for the Ack Window to
timeout on lost packets. If the ACK setting is too low then the ACK window will have expired
