You Cannot Log In to the Modem Router

If you are unable to log in to the modem router from a computer on your local network and
use the web management interface, check the following:
• If you are using an Ethernet-connected computer, check the Ethernet connection
between the computer and the modem router.
• If the computer is set to a static or fixed IP address (this setting is uncommon), either
change the computer to obtain an IP address automatically from the modem router
through DHCP, or change the IP address of the computer to a static or fixed IP address in
the 192.168.0.2–192.168.0.254 range.
• Make sure that your computer can reach the modem router's DHCP server. Recent
versions of Windows and Mac OS generate and assign an IP address if the computer
cannot reach a DHCP server. These autogenerated 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 router and reboot your computer.
