LAN LED Is Off
If the LAN LED is off when you connect a device to the Gigabit Ethernet port of
the modem, check the following:
•
The Ethernet cable connections are secured at the modem and at the device at the
other end of the cable.
•
The power of the device at the other end of the cable is turned on.
•
You are using the correct cable.
You Cannot Log In to the Modem
If you are unable to log in to the modem’s web pages from a device that is connected
to the modem, check the following:
•
If you are using an Ethernet-connected computer, check the Ethernet connection
between the computer and the modem (see LAN LED Is Off on page 78).
•
Make sure that Java, JavaScript, or ActiveX is enabled in your browser. If you are
using Internet Explorer, click the Refresh button to be sure that the Java applet is
loaded.
•
Try quitting the browser and launching it again.
•
Make sure that you are using the correct login information. See the modem label
for the default password. Make sure that Caps Lock is off when you enter this
information.
•
Make sure that your computer does not use a static IP address but is configured to
receive an IP address automatically with DHCP.
•
Turn off and on both the modem and the device that is connected to the modem.
•
If your modem’s IP address was changed and you do not know the current IP address,
clear the modem’s configuration to factory defaults. This sets the modem’s IP address
to 192.168.5.1. For more information, see Return the Modem to Its Factory Default
Settings on page 52.
