Internet LED Is Red
If the Internet LED is red, the device could not connect to the Internet. Verify the following:
• Check that
your login credentials are correct. See Log In to the N600 Modem Router on
page 24 for more information.
• Check that
the information you entered on the Basic Settings screen is correct. See
Manual Setup (Basic Settings) on p
age 28.
• Check with
your ISP to verify that the multiplexing method, VPI, and VCI settings on the
ADSL settings screen are correct.
• Find o
ut if the ISP is having a problem. If it is, wait until that problem is cleared up and try
again.
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 150.
• 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 27 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 28.
