Connecting to the Gateway’s Main 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 PC’s IP address is on the same subnet as the gateway. If you are using the
recommended addressing scheme, your PC’s address should be in the range of 192.168.0.10 to
192.168.0.254. Refer to the link to the online document “ITCP/IP Networking Basics” in
Appendix B for help configuring your computer.
• If your gateway’s IP address has been changed and you don’t know the current IP address,
clear the gateway’s configuration to factory defaults. This will set the gateway’s IP address to
192.168.0.1. This procedure is explained in “Enabling Remote Management” on page 5-9.
• Make sure 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 you are using the correct login information. The gateway has two user names both
lower-case (Caps Lock should be off):
– The superuser login name is mso with the default password of changeme.
– The other login name is admin with the default password of password.
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 may have occurred, but
the Web browser may be caching the old configuration.
Note: If your PC’s IP address is shown as 169.254.x.x:
Recent versions of Windows and MacOS will generate and assign an IP
address if the computer cannot reach a DHCP server. These auto-generated
addresses are in the range of 169.254.x.x. If your IP address is in this range,
check the connection from the PC to the gateway and reboot your PC.
