Cannot log in to the cable modem
If you cannot access your cable modem from a computer that is connected to your cable
modem or to a router that is connected your cable modem, check the following:
•
If your computer is connected to your cable modem with an Ethernet cable, check
the connection.
•
Make sure that Java, JavaScript, or ActiveX is enabled in your browser. If you are
using Internet Explorer, click the Refresh button to make 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. Your cable modem user

When entering configuration settings, be sure to click the Apply button before
moving to another page, or your changes are lost.
