Testing the LAN Path to Your Router
To test the LAN connection to the router, do the following:
G
Check the Ethernet wiring connection between your computer
and the server.
G
Use TCP/IP’s PING command to determine if the TCP/IP settings
on both your computer and your server are correct. For example,
if your computer is a PC with Windows, then open an MS-DOS
command window and enter the following commands:
ping 192.168.1.1
This command assumes that the IP address of the router is
192.168.1.1. If the router does not respond to the ping command,
contact technical support.
Testing the LAN Path from your PC to a Remote Device
To test the LAN connection to a remote device, type in the PING -n 10
command followed by the IP address of a remote device, such as your
ISP’s DNS server. If the path is functioning properly, the remote device
will send replies in response to the PING command. If no replies are
received, do the following:
G
Make sure your PC has the IP address of your router as the default
gateway. If the IP configuration of your PC is assigned by DHCP,
this information will not be visible in the control panel network
utility. Start the Run window and run winipcfg to see if the IP
address of the router appears as the Default Gateway.
G
Make sure the network address of your PC (the portion of the IP
address specified by the netmask) is different from the network
address of the remote device.
G
Check the System Information table with the Web configuration
tool to verify the WAN status. If the WAN status is down, make sure
your Cable/DSL modem is connected and operating.
G
If your ISP assigned a host name to your PC, enter the host name
as the router name in the WAN Configuration.
