N150 Wireless ADSL2+ Modem Router DGN1000
Cannot Obtain an Internet IP Address
If your wireless modem router cannot access the Internet, and your Internet LED is green or
blinking green, check whether the wireless modem router can obtain an Internet IP address
from the ISP. Unless you have been assigned a static IP address, your wireless modem
router has to request an IP address from the ISP. You can determine whether the request
was successful as follows:
1. Access the
router menus at http://192.168.0.1 and log in.
2. Unde
r Maintenance, select Router Status and check that an IP address shows for the WAN
port. If 0.0.0.0 shows, your wireless modem router has not obtained an IP address from your
ISP.
If your router cannot obtain an IP address from the ISP, the problem might be one of the
f
ollowing:
• If you have se
lected a login program, the service name, user name, or password might be
incorrect. See Debug PPPoE or PPPoA o
n page 89.
• Y
our ISP might check for your computer’s host name. Assign the computer host name of
your ISP account to the wireless modem router in the browser-based Setup Wizard. See
Setup Wizard on
page 24 for more information.
• Y
our ISP allows only one Ethernet MAC address to connect to the Internet, and might
check for your computer’s MAC address. In this case, do one of the following:
- I
nform your ISP that you have bought a new network device and ask them to use the
router’s MAC address.
- Con
figure your router to spoof your computer’s MAC address through the Basic
Settings screen. See Manual Setup (Basic Settings) on
page 25.
Debug PPPoE or PPPoA
 To debug the PPPoE or PPPoA connection:
1. Access the
router menus at http://192.168.0.1 and log in.
2. Unde
r Maintenance, select Router Status.
3. Click the Co
nnection Status button.
4. If all of the step
s indicate OK, your PPPoE or PPPoA connection is working.
5. If any of the step
s indicate Failed, you can attempt to reconnect by clicking Connect.
The wireless modem router continues to attempt t
o connect indefinitely. If you do not
connect after several minutes, check that the service name, user name, and password
you are using are correct. Also check with your ISP to be sure that there is no problem
with their service.
