How can I set the AP11's channel to 100 (in DFS)
@QGaF9T From your main page click on inventory then on the right side of the page is a sprocket wheel click on that then you can select your channel width. Then you will see all the channels that are active, just click on them to change them to grey or inactive.
Click More options > Wireless options > Radio Management
on 5GHz Radio, you can select channel 100 and apply.
