No Option to Change Channel on Almond/Wifi AP

[Curmudgeon10]

There's a PDF out there on the net showing an Almond pub with instructions on how to change the channel: go to Wifi settings, hit "Change" and select a different channel.

Problem: my Almond (just purchased via Amazon ten days ago, so I assume it is an "Almond 3" ??), does not show a "Change" button in Wifi settings.  The channel is shown as Channel 7, and is "greyed out."

So how do I change the channel?

@ Curmudgeon10,

Disable the AP mode, so it reverts back to Router and allows you to change the channel then put it back in AP mode.
