After changing the operation mode to Access Point Router mode, the
ethernet port on ECB300 will act as a WAN port, which means you can only
hardwire a modem, router or a switch to it. The ethernet port will be the
WAN side and the wireless connection will be the LAN side. The modem,
router or switch that will be wired to the ECB300 on AP Router mode should
be on a different subnet. To access the ECB300 again connect wirelessly to
the ECB300. ECB300 will act as the Router/DHCP server.
