ACK Policies
WMM specifies the Normal ACK and No ACK policies.
− According to the No ACK policy, no ACK packet is used during wireless packet transmission
to acknowledge packet reception. This policy is applicable to scenarios where interference
is mild and can effectively improve transmission efficiency. In case of strong interference,
lost packets are not sent again if this policy is adopted. This leads a higher packet loss rate
and reduces the overall performance.
− According to the Normal ACK policy, each time a receiver receives a packet, it sends back
an ACK packet to acknowledge packet reception.
7.4.2 Changing the WMM settings
By default, the WMM function of the AP is enabled and the Optimized For Capacity mode is
adopted. Procedure for changing the WMM settings:
Step 1 Choose Wireless > WMM Setup.
Step 2 Set the WMM to Enable.
Step 3 Select the required WMM optimization mode.
Step 4 If you select Custom, set the WMM parameters as required.
Step 5 Click Save.
