the modem router and reboot your computer.

Troubleshoot the ISP Connection

When your modem router is unable to access the Internet and your Internet LED is on,
register the cable MAC address or device MAC address of your modem router with your
cable service provider.
Additionally, your computer does not have the modem router that is configured as its TCP/IP
gateway. If your computer obtains its information from the modem router by DHCP, reboot the
computer and verify the gateway address.

packet to the designated device. The device then responds with an echo reply. You can
easily troubleshoot a TCP/IP network by using the ping utility in your computer or
workstation.
