static IP address, the
modem router
requests an IP address from the ISP.You can determine whether
the request was successful using the web management interface.
To check the Internet IP address:
1.
Launch an Internet browser from a computer or WiFi device that is connected to the network.
2.
Type
.
A login window opens.
3.
Enter the user name and password for the
modem router
.
The user name is
admin
. The default password is
password
. The user name and password are
case-sensitive.
4.
Click the
OK
button.
The BASIC Home page displays.
5.
Select
ADVANCED > ADVANCED Home
.
The ADVANCED Home page displays.
6.
In the Internet Port pane, check to see that the
IP Address
field shows a valid IP address.
If the field shows
0.0.0.0
, your
modem router
did not obtain an IP address from your ISP.
If your
modem router
cannot obtain an IP address from the ISP, the problem might be one of the following:
•
Your Internet service provider (ISP) might require a login program. Ask your ISP whether they require
PPP over Ethernet (PPPoE) or some other type of login.
•
If you selected a login program, the service name, user name, or password could be incorrectly set.
Before you make any changes, verify that the
modem router
can get a PPPoE or PPPoA connection
(see
Verify the PPPoE or PPPoA Connection
on page 302).
•
Your ISP might check for your computer’s host name. Assign the computer host name of your ISP
account as the account name. For more information, see one of the following sections:
•
Manually Set Up an ADSL Internet Connection
on page 51
•
Manually Set Up a VDSL Internet Connection
on page 63
•
Manually Set Up a Cable or Fiber Internet Connection
on page 73
•
If your ISP allows only one Ethernet MAC address to connect to Internet and checks for your computer’s MAC
address, inform your ISP that you bought a new network device and ask them to use the
modem router
’s MAC
address.
•
Configure your
modem router
to clone your computer’s MAC address. For more information, see one of the
following sections:

Reestablish the PPPoE or PPPoA Connection
If your PPPoE or PPPoA configuration information is correct (see
Verify the PPPoE or PPPoA Connection
on page 302), your PPPoE or PPPoA connection is working.
To reconnect if your PPPoE or PPPoA connection does not function:
1.

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:

Troubleshoot Internet Browsing
If your
modem router
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:
•
The traffic meter is enabled, and the limit was reached.
By configuring the traffic meter not to block Internet access when the traffic limit is reached, you can
resume Internet access (see
Unblock the Traffic Meter After the Traffic Limit Is Reached
on page 263).
If your ISP sets a usage limit, they might charge you for the overage.
•
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 router
, 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 router
might not be configured as the TCP/IP router on your computer.
For information about TCP/IP problems, see
Troubleshoot Your Network Using the Ping Utility
on
page 305.
If your computer obtains its information from the
modem router
by DHCP, reboot the computer and
verify the
modem router
address.
Changes Are Not Saved
If the
modem router
does not save the changes that you make in the web management interface, do the
following:
•
When entering configuration settings, always click the
Apply
button before moving to another page
or tab or your 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 the WiFi Connectivity
If you are experiencing trouble connecting over WiFi to the
modem router
, try to isolate the problem:
•
Make sure that the WiFi settings in your WiFi device and
modem router
match exactly.
For a device that is connected over WiFi, the WiFi network name (SSID) and WiFi security settings
of the
modem router
and WiFi computer must match exactly. The default SSID and password are on
the product label (see
Bottom Panel Product Label
on page 17).
•
Does the WiFi device that you are using find your WiFi network?
Diagnostics and Troubleshooting
304
Nighthawk AC1900 WiFi VDSL/ADSL Modem Router Model D7000
Page 305 / 312
If not, check the WiFi LED
on the top of the
modem router
. If this LED is off, both WiFi radios
might be disabled. For more information about the WiFi radios, see
Control the WiFi Radios
on page
123.
•
If you disabled the
modem router
’s SSID broadcast, your WiFi network is hidden and does not display
in your WiFi client’s scanning list. (By default, SSID broadcast is enabled.) For more information, see
View or Change the Basic WiFi Settings
on page 102.
•
Does your WiFi device support the security that you are using for your WiFi network (WEP, WPA, or
WPA2)? For information about changing the WiFi security, see
View or Change the Basic WiFi Settings
on page 102.
If you want to change the WiFi settings of the
modem router
’s main network, use a wired
connection to avoid being disconnected when the new WiFi settings take effect.
Tip
If your WiFi device finds your network but the signal strength is weak, check these conditions:
•
Is your
modem router
too far from your WiFi device or too close? Place your WiFi device near the
modem router
but at least 6 feet (1.8 meters) away and see whether the signal strength improves.
•
Are objects between the
modem router
and your WiFi device blocking the WiFi signal?
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 Router
You can ping the
modem router
from your computer to verify that the LAN path to your
modem router
is
set up correctly.
To ping the
modem router
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 router
, as in this example:
ping 192.168.0.1
3.
Click the
OK
button.
A message such as the following one displays:
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
