or to a router that is connected the cable modem, check the following:
• If your computer is connected to the cable modem with an Ethernet cable, check the
connection.
• Make sure that your computer’s IP address is on the same subnet as the cable modem.
The IP address of your computer must be in the range of 192.168.100.2 to
192.168.100.254.
