EZ CONNECT™ 802.11A WIRELESS ACCESS POINT

The DTIM is the interval between two synchronous frames with broadcast information. If you set the value to 2, the access point will save all multicast frames for the BSS and forward them after every second beacon. Having smaller DTIM intervals delivers multicast frames in a more timely manner, causing stations in Power Save mode to wake up more often and drain power faster. Having higher DTIM values, though, delays the transmission of multicast frames.

(Default: 1)

Transmit Threshold

Fragment Length (256-2346): The “Fragment Length” can be set between 256 and 2,346. If the packet size is smaller than the preset Fragment size, the packet will not be segmented.

Fragmentation of the PDUs can increase the reliability of transmission because it increases the probability of a successful transmission due to smaller frame size. If there is significant interference present or collisions due to high network utilization, try setting the fragment size to send smaller fragments. This will enable the retransmission of smaller frames much faster. However, it is more efficient to set the fragment size larger if very little or no interference is present because it requires overhead to send multiple frames. (Default: 2346)
