4.8.4.1Editing Access Port Adoption WMM Settings

Use the Edit screen to modify a WMM profile's properties (AIFSN, Transmit Ops, 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 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 802.11a radio or an 802.11 bg 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 will causes lower-priority traffic to wait longer before trying to access the medium.
