3. Select a radio and click the 

 button to modify its properties. For more information, see 

Use the Edit screen to modify a WMM profile's properties (AIFSN, Tx Op, Cw Min and CW Max). Modifying 
these properties may be necessary as Access Categories are changed and transmit intervals need to be 
adjusted to compensate for larger data packets and contention windows.

To edit existing WMM Settings:

1. Select 

from the main menu tree. 

2. Click the 

tab.

3. Select a radio from the table and click the 

 button to launch a screen displaying the WMM 

configuration for that radio. 

Displays the Access Category currently in use. There are four categories: Video, Voice, Best 
Effort and Background. Click the Edit button to change the current Access Category. Ensure 
the Access Category reflects the radio’s intended network traffic. 

Displays the current Arbitrary Inter-frame Space Number. Higher-priority traffic categories 
should have lower AIFSNs than lower-priority traffic categories. This will causes lower-
priority traffic to wait longer before trying to access the medium.

Displays the maximum duration a device can transmit after obtaining a transmit opportunity. 
For Higher-priority traffic categories, this value should be set higher.

Displays the CW Max to make the Contention Window. From this range, a random number 
is selected for the back off mechanism. Lower values are used for higher priority traffic.

Displays the CW Min to make the Contention Window. From this range, a random number is 
selected for the back off mechanism. Lower values are used for higher priority traffic.
