Troubleshooting the Web Management Interface

If you are unable to access the modem's Web Management interface from your computer check the
following:
• Check the Ethernet connection between the computer and the router as described in the
previous section.
• If your computer is directly connected to the modem, make sure your computer's IP address is
on the same subnet as the modem. If you are using the recommended addressing scheme, your
computer's address should be in the range of 192.168.0.2 to 192.168.0.254. Follow the

Note: If your computer's IP address is shown as 169.254.x.x:
Recent versions of Windows and MacOS will generate and assign an IP
address if the computer cannot reach a DHCP server. These auto-generated
addresses are in the range of 169.254.x.x. If your IP address is in this range,
check the connection from the computer to the modem and reboot your
computer.
• If your modem is connected to your computer via a router, make sure the computer's IP
address is on the same subnet as the router, and the router is on a different subnet from the
modem. The LAN IP addresses of the modem and router will normally be printed on a label on
the bottom or rear of the unit. For details about changing the modem's IP address, see

• If your modem's IP address was changed and you do not know the current IP address, clear the
router's configuration to factory defaults. This will set the router's IP address to 192.168.0.1.
