To edit the existing WMM settings:
1. Select Network Setup > Radio Adoption Defaults from the main menu tree.
2. Click the WMM tab.
3. Select a radio from the table and click the Edit button.
The AP Type identifies whether the radio is an 802.11b, 802.11bg and 802.11bgn or 802.11a and 802.11an radio. This
value is read-only and cannot be modified. There are four editable access categories: Video, Voice, Best Effort and
Background.
4. Enter a number between 0 and 15 for the AIFSN value for the selected radio.
The AIFSN value is the current Arbitrary Inter-frame Space Number . Higher-priority traffic categories should have lower
AIFSNs than lower-priority traffic categories. This causes lower-priority traffic to wait longer before trying to access
the medium.
5. Enter a number between 0 and 65535 for the Transmit Ops value.
The Transmit Ops value is the maximum duration a device can transmit after obtaining a transmit opportunity. For
higher-priority traffic categories, this value should be set higher.
6. Enter a value between 0 and 15 for the Contention Window minimum value.
The CW Minimum is combined with the CW Maximum 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.
7. Enter a value between 0 and 15 for the Contention Window maximum value.
The CW Maximum is combined with the CW Minimum 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.

something goes wrong in the transaction between the applet and the switch.
9. Click OK to use the changes to the running configuration and close the dialog.
