correctly.



From the Windows toolbar, click the Start button and select Run.

In the field provided, type ping followed by the IP address of the router, as in this example:
ping www.routerlogin.net

Click the OK button.

You see a message like this one:

Pinging <IP address > with 32 bytes of data

If the path is working, you see this message:

Reply from < IP address >: bytes=32 time=NN ms TTL=xxx

If the path is not working, you see this message:

Request timed out

If the path is not functioning correctly, one of the following problems might be present:

Wrong physical connections

For a wired connection, make sure that the numbered LAN port LED is lit for the port to 
which you are connected.

Check that the appropriate LEDs are on for your network devices. If your router and 
computer are connected to a separate Ethernet switch, make sure that the link LEDs are 
lit for the switch ports that are connected to your computer and router.

Wrong network configuration

Verify that the Ethernet card driver software and TCP/IP software are both installed and 
configured on your computer. 

Verify that the IP address for your router and your computer are correct and that the 
addresses are on the same subnet.

After verifying that the LAN path works correctly, test the path from your computer to a 

remote device.

From the Windows toolbar, click the Start button and select Run.

In the Windows Run window, type

ping -n 10 <IP address>

where <IP address> is the IP address of a remote device such as your ISP DNS server.
