DR404 works as a STA, in router mode(software is N-Ver). Connected to the AP and obtained an IP address from the
AP such as 192.168.1.101 in the below diagram. DR404 forms a subnet(default 10.10.100.254) which distributes the IP
address to the devices that connect to its Ethernet interface. As below, PC1 in the subnet, for DR404 works in router mode,
PC1 can connected to the PC2, but PC2 can not connected to PC1.
