WMM is designed to provide Quality of Service (QoS) support for
multi-media traffic on your network. The multi-media applications must
also support WMM. When they do, WMM facilitates smoother traffic
flow for these traffic types. WMM cannot be turned off.
If you find wireless traffic is not flowing well, you can turn on No-
Acknowledgement. No-Acknowledgement improves packet throughput
with the trade-off of higher error rates. In many cases this can result in
an overall improvement in performance.
Power Save Support is designed to support client devices with the
Power Save feature. The Power Save feature extends battery life by
reducing power consumption. However, sometimes this feature results
in suboptimal wireless performance. You can turn Power Save Support
Off and see if that improves performance in your network. Select the
tab for the band you are experiencing suboptimal performance with.
Then select Off and click Save.
