4. Wireless Settings

AirLive N.TOP User’s Manual 32

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 and the returning

packet will be dropped, greatly lowering throughput. By having the ability to adjust the

ACK setting we can effectively optimize the throughput over long distance links. This

is especially true for 802.11a and 802.11g networks. Setting the correct ACK timeout

value need to consider 3 factors: distance, AP response time, and interference. The

N.TOP provides ACK adjustment capability in form of either distance or direct input.

When you enter the distance parameter, the N.TOP will automatically calculate the

correct ACK timeout value, it should have a value of 0-255 sec.

4.4 Access Control
