Access the Gateway Menu
If you are unable to access the gateway's main menu from a computer on your local network,
check the following:
•
Check the Ethernet connection between the computer and the gateway as described in
the previous section.
•
Make sure that your computer's IP address is on the same subnet as the gateway. If you
are using the recommended addressing scheme, your computer's address should be in
the range of 10.1.10.10 to 10.1.10.199.
Note:
If your computer's IP address is shown as 169.254.x.x:
Recent versions of Windows and Mac OS generate and assign an IP
address in this range if the computer cannot reach a DHCP server.
Check the connection from the computer to the gateway and reboot
your computer.
•
If your gateway's IP address has changed and you do not know the current IP address,
clear the gateway's configuration to its factory defaults, which returns the IP address to
10.1.10.1. This procedure is explained in
•
Make sure that your browser has Java, JavaScript, or ActiveX enabled. If you are using
Internet Explorer, click Refresh 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. The gateway has two user
names, both lowercase:
-
The superuser login name is mso with the default password of D0nt4g3tme.
-
The other login name is cusadmin with the default password of highspeed.
If the gateway does not save changes you have made, check the following:
•
When entering configuration settings, be sure to click the apply button before moving to
another screen, or your changes are lost.
•
Click the Refresh or Reload button in the web browser. The changes might have
occurred, but the browser could be caching the old configuration.
Troubleshoot the ISP Connection
If the gateway does not access the Internet, you might need to register the cable MAC
address or device MAC address with the cable service provider. Additionally, your computer
might not have the gateway configured as its TCP/IP gateway. If your computer obtains its
information from the gateway by DHCP, reboot the computer and verify the gateway address.
