Wireless Cable Modem Gateway CG814WG v3 Reference Manual

•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 “Internet Networking and TCP/IP Addressing” on page B-1for help configuring your computer.

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.

•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 “Diagnostics” on page 4-10.

•Make sure your browser has Java, JavaScript, or ActiveX enabled. If you are using Internet Explorer, click Refresh to be sure the Java applet is loaded.

•Try quitting the browser and launching it again.

•Make sure you are using the correct login information. The factory default login name is admin and the password is password. Make sure that CAPS LOCK is off when entering this information.

If the gateway does not save changes you have made in the Web Configuration Interface, check the following:

•When entering configuration settings, be sure to click the APPLY button before moving to another menu or tab, 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.

Troubleshooting the ISP Connection

If your gateway is unable to access the Internet and your Cable Link LED is on, you may need to register the Cable MAC Address and/or Device MAC Address of you gateway with your cable service provider. This is described in “Connecting the CG814WG v3 Gateway” on page 1-4.

Additionally, your PC may not have the gateway configured as its TCP/IP gateway. If your PC obtains its information from the gateway by DHCP, reboot the PC and verify the gateway address. See the link to the online document “Internet Networking and TCP/IP Addressing” on page B-1
