Troubleshooting the Installation

Use the following tips to troubleshoot the installation.

the cable modem and wait for 5 seconds and power on the modem again. If the
problem still exists, there may be a hardware problem.

Ethernet cables are connected.

modem.

outlet and plugging it back in. Wait for the cable modem to re-establish
communications with your cable service provider.
