v3.0, September 2005
A DNS server is a host on the Internet that translates Internet names (such as www addresses)
to numeric IP addresses. Typically your ISP will provide the addresses of one or two DNS
servers for your use. If you entered a DNS address during the ADSL modem router’s
configuration, reboot your computer and verify the DNS address as described in
“Preparing a
Computer for Network Access:” in Appendix A
. Alternatively, you can configure your
computer manually with DNS addresses, as explained in your operating system
documentation
.
Your computer may not have the ADSL modem router configured as its TCP/IP ADSL
modem router.
If your computer obtains its information from the ADSL modem router by DHCP, reboot the
computer and verify the ADSL modem router address as described in
“Preparing a Computer
for Network Access:” in Appendix A
.
Troubleshooting a TCP/IP Network Using the Ping Utility
Most TCP/IP terminal 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 TCP/IP
network is made very easy by using the ping utility in your computer.
Testing 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 PC running Windows 95 or later:
1.
From the Windows toolbar, click the Start button and select Run.
2.
In the field provided, type Ping followed by the IP address of the router, as in this example:
ping 192.168.0.1
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:
