In general two IP addresses are required by a home network, from which one is used by the internal or home network system which is known as LAN in easy language and the other is used by the external or internet connection and known as WAN. Finding the default router IP 192.168.1.1 or modem IP address is not hard.
Usually, it is 192.168.0.1, not 1.1\
Also, usually the default login and password for your modem is: "admin"
