This is such a simple feature that so many other products support I am baffled why Almond would not support it. It is really simple, just make a Wireless Bridge mode where it connects to another Wifi AP without rebroadcasting and thus causing additional congestion on the existing channel.
The way you are forcing people to do it now just causes additional security holes, degrades the existing wifi channe, and is completely unnesssary.
Please, Please, Please, put this on your list to allow us to disable the wifi repeater.
