For my current modem, I type the IP 192.168.100.1. Sometimes the modem
manual tells you the IP. In this case, I looked it up in Network in
System Preferences. The procedure to find the IP is probably a little
different in Windows.


I doubt the modem manual would tell the IP address as it is assigned by the
internet system. You may be thinking of the MAC number.

The ISP assigns a WAN IP. To ask the modem, "How's it going?" the
computer uses the LAN IP.

If I ping my WAN IP, the signal will go to my ISP and back. If I just
want to ping my modem, I use the LAN IP.
