@dero,

By definition, a range extender works to forward the wireless signal by repeating it. To do what you are looking at, you will need to make sure that you purchase a device, range extender or other, that supports AP(Access Point Mode). If you take a look at the product page for the RE315, there is a designated panel stating that the Range Extender offers AP mode. As such though, our OneMesh System does not currently support an ethernet backhaul.
