That's not correct when you use them in access point mode with a cat5
back to the router.

Then it's not an extender (aka repeater) is is it? It is, as you say,
an access point.

You still need to be careful about channels and any overlap of
channels and coverage but you don't get the instant 50% reduction in
through put that you do with an extender/repeater.

There's an Android app* for looking to see which channels are in use.
