If there are several networks/network adapters, each network must have its own IP address range, otherwise the system won't know on which network it has to send the datas data (unless specific exception, for example when "teaming" several adapters, but that is currently not supported on Merging devices).
E.g, network 1 is using 192.168.0.9 and network 2 is using 192.168.0.39 => Not OK
But if network 2 is using 10.0.0.47, the device will be able to communicate on both networks properly.
