Broadband ADSL2+ Modem DM111PSPv2
Cannot Load an Internet Web Page
If your modem can obtain an IP address, but your browser cannot load any Internet web
pages:
•
Your computer might not recognize any DNS server addresses.
A DNS server is a host on the Internet that translates Internet names (such as www
addresses) to numeric IP
addresses. Typically your ISP provides the addresses of one or
two DNS servers for your use. If you entered a DNS address during the broadband
ADSL2+ modem’s configuration, reboot your computer, and verify the DNS address.
Alternately, you can configure your computer manually with DNS addresses, as explained
in your operating system documentation
.
•
Your computer might not have the modem configured as its TCP/IP router.
If your computer obtains its information from the modem by DHCP, reboot the computer,
and verify the modem address.
TCP/IP Network Not Responding
Most TCP/IP terminal devices and modems have a ping utility for sending an echo request
packet to the designated device. The device responds with an echo reply to tell whether a
TCP/IP network is responding to requests.
Test the LAN Path to Your Modem
You can ping the modem from your computer to verify that the LAN path to your modem is set
up correctly.

In the field provided, type
ping

3.
Click
OK
.
a.
You should see a message like this one:
“Pinging <IP address> with 32 bytes of data”
b.
If the path is working, you see this message:
“Reply from < IP address >: bytes=32 time=NN ms TTL=xxx”
c.
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:
