Troubleshoot Your Network Using the Ping Utility
Most network devices and routers contain a ping utility that sends an echo request packet to
the designated device. The device then responds with an echo reply. Troubleshooting a
network is made very easy by using the ping utility in your computer or workstation.
Test the LAN Path to Your Router
You can ping the router from your computer to verify that the LAN path to your router is set up
correctly.
To ping the router from a running Windows PC:
1. From the Win
dows toolbar, click Start, and then select Run.
2. In th
e field provided, type ping followed by the IP address of the router, as in this example:
ping www.routerlogin.net
3. Click OK.
You should 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, you could have one of the following problems:
• W
rong physical connections
For a wired connection, make sure that the numbered LAN port LED is on for the port to
which yo
u are connected.
Check that the appropriate LEDs are on for your network devices. If your router and
compute
r are connected to a separate Ethernet switch, make sure that the link LEDs are
on for the switch ports that are connected to your computer and router.
• W
rong network configuration
