Section 3 - Configuration
CWmin: The value specified for the Minimum Contention Window is the lower limit of a range for the initial random backoff wait time.
Setting this value gives the DAP-3310 a starting point before beginning to double the window size when a collision is detected.
CWMax: The value specified in the Maximum Contention Window is the upper limit for this doubling of the random backoff. This doubling
continues until either the data frame is sent or the Maximum Contention Window size is reached.
AIFS: The Arbitration Inter-Frame Spacing (AIFs) specifies a wait time (in milliseconds) for data frames. The AIFs ensures that multiple
access points do not try sending data at the same time but instead wait until a channel is free.
TxOp Limit: The Transmission Opportunity (TXOP) is an interval of time when a WMM client station has the right to initiate transmissions onto
the wireless medium.
ACM BIT: Enabling this checkbox will allow the AP to broadcast the admission control bit.
No ACK Policy When the no acknowledgement (No ACK) policy is used, the recipient does not acknowledge received packets during wireless
bit: packet exchange.
