Netgear Dm200 Broadband High Speed Dsl Modem User Manual

							If you cannot connect after several minutes, you might be using an incorrect service name, user name, or
password. Or your ISP might not be able to provide an Internet connection. For more information, see one
of the following sections:
•
Specify an ADSL Connection With a Login and PPPoA or PPPoE Service on page 34
• Specify a 
VDSL Connection With a Login and PPPoE Service
 on page 42 Unless you connect manually, the 
modem does not authenticate using PPPoE or
PPPoA until data is transmitted to the network.
Note
Troubleshoot Internet Browsing
If your modem can obtain an IP address but your computer is unable to load any web pages from the Internet,
it might be for one of the following reasons:
• 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 when you set up the modem, reboot your computer and verify the
DNS address

. Alternatively, you can configure your computer manually with DNS addresses, as explained
in your operating system documentation
.
• The 
modem might not be configured as the TCP/IP router on your computer.
F
or information about TCP/IP problems, see Troubleshoot Your Network Using the Ping Utility on page
101
.
If your computer obtains its information from the 
modem by DHCP, reboot the computer and verify the
modem
 address.
Changes Are Not Saved If the 
modem does not save the changes that you make on a modem web page, do the following:
• When enter
ing configuration settings, always click the Apply button before moving to another page or
tab or y

our changes are lost.
• Click the 
Refresh or Reload button in the web browser. It is possible that the changes occurred but
that the old settings remain in the web browser’s cache.
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. You can easily troubleshoot a network using the ping
utility in your computer or workstation.
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. Troubleshooting
101

							To ping the modem from a Windows computer:
1.
From the Windows taskbar, click the Start
 button and select Run.
2. In the field provided, enter 
ping followed by the IP address of the modem, as in this example:
ping 192.168.5.1
3. Click the 
OK button.
A message such as the following one displays:
Pinging  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 occurring:
• Wrong physical connections
Make sure that the LAN LED is lit.
If your modem and computer are connected through a separate router or Ethernet switch, make sure
that the link LEDs are lit f
 or the router or switch ports that are connected to your computer and modem.
• 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 modem and your computer are correct and that the addresses are
on the same subnet.
T

est the Path From Your Computer to a Remote Device
After you verify that the LAN path works correctly, test the path from your computer to a remote device.
To test the path from your computer to a remote device: 1.
From the Windows toolbar, click the Start
 button and select Run.
2. In the field pro
vided, enter ping -n 10 IP address
.
IP address
 is the IP address of a remote device such as your ISP’s DNS server.
If the path is functioning correctly, replies as described in Test the LAN Path to Your Modem on page 101
displa

y. If you do not receive replies, do the following:
• Check to see that the IP address of your 
modem is listed as the default router in your computer. If the
IP configur
ation of your computer is assigned by DHCP, this information is not visible in your computer’s
Network Control Panel. Verify that the IP address of the modem
 is listed as the default router.
• Check to see that the network address of your computer (the portion of the IP address specified by the
netmask) is different from the network address of the remote device. Troubleshooting

							•
If your ISP assigned a host name to your computer, enter that host name as the account name. For
more information, see one of the following sections:
-Specify an ADSL Connection Without a Login on page 30
- Specify a 
VDSL Connection Without a Login
 on page 38
• Y
our ISP might be rejecting the Ethernet MAC addresses of all but one of your computers.
Many broadband ISPs restrict access by allowing traffic only from the MAC address of your modem,
but some additionally restrict access to the MAC address of a single computer connected to that modem.
In this case, configure your modem
 to clone or spoof the MAC address from the authorized computer.
