In each case, the computer connected to the three test routers was able to access the main router web interface (192.168.4.1), the modem on 192.168.100.1 and the Internet. To these three routers, 192.168.4.1 was their default TCP/IP gateway and 192.168.4.100 was their WAN-side IP address.Įach router had a single computer connected to it, via Ethernet. That is, the main LAN is 192.168.4.x and, before connecting the routers to it, they were configured to use 192.168.55.x. ![]() Each router had its own network, separate from the main LAN. Three routers were tested by connecting them to my LAN. As you would expect, the procedure and terminology was totally different in each router.
