You'll need to use your wireless router as just a switch in order to
avoid double-NAT.  If you disable its DHCP, and ensure that it's got an
IP address on the right subnet, all you have to do is plug the Atnex
equipment into one of the normal ports on your wireless router.

Do _not_ plug your Atnex equipment into the "WAN" or "uplink" port on
your router.  If you do that, then you're not using it as a switch,
you're using it as a router, and you'd need to configure the device to
properly handle its own subnetwork.

Doing it this way takes advantage of the fact that all of the non-uplink
ports are bridged together (that is, after all, what a switch is: just a
multiport network bridge).  So, once you plug one of the normal ports
into one of the Atnex ports you will be able to use the wireless network
as an extension of the network serviced by the Atnex device.

Does that all make sense?
