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
name admin is lowercase (Caps Lock is off).
•
Make sure that your computer’s IP address is on the same subnet as the cable modem.
The IP address of your computer must be in the range of 192.168.100.2 to
192.168.100.254.
If your cable modem does not save changes you made, do the following:
•
When entering configuration settings, be sure to click the Apply button before
moving to another page, or your changes are lost.
•
Click the Refresh or Reload button in the web browser. It is possible that the changes
occurred, but the web browser is caching the old configuration.
Troubleshoot the cable internet connection
If your cable modem cannot access the Internet but the Online LED lights white, make
sure that the cable MAC address or device MAC address of your cable modem is
registered with Internet service provider (see Activate Your Internet Service on page
10).
