Hi Trevor,
The ZD WebUI is meant to be more user friendly than command line. From the
Configure tab, Services on the left, the boxes to configure 2.4/5G channel selection
(self healing) are found. We suggest to check the 5G box to enable Automatic
adjustment, and pick ChannelFly from the dropdown (rather than Bkgd Scanning).
Apply this change and let your APs use the algorithm which entails an off-channel
scan an building of an internal database with interference seen. After at least two
hours, the AP ought to have selected a better-than-default channel. You can then
change the ZD Configure/Services, and uncheck the 5G Automatically adjust box.
This only applies to 5G band when you have our newest 11ac AP models in use.
You can use background scanning or channelfly algorithm on your 2.4G channels,
and leave it running. I hope this is helpful.
