If the wifi you installed is completely independent you should be able to use the whitelist sensors to individual APs.

At initial deploy you've confirmed the sensors connect to preferred AP?

If so,
Are the sensors on fixed RF channels? Could the Ruckus ZD be managing the environment in a way that leaves behind the sensors?

Whitelisting might solve the problem, but you won't know why its happening in the first place.


Google search only turns up Zapo USB -> wifi adaptors being sold by third parties and a single listing on Amazon: [Link: a.co]
I'd have serious concerns about this.

Is the wifi configuration managed by the adaptor or by the flood sensor?
