N300 Wireless ADSL2+ Modem Router DGN2200v3 
Internet LED Is Red
If the Internet LED is red, the device was unable to connect to the Internet. Verify the 
following:
•     
Check that your login credentials are correct, or that the information you entered on the 
Basic Settings screen is correct.
•     
Check with your ISP to verify that the multiplexing method, VPI, and VCI settings on the 
ADSL settings screen are correct.
•     
Check if your ISP has a problem—it might not be that the modem router cannot connect 
to the Internet but, rather that your ISP that cannot provide an Internet connection.
Obtaining an Internet IP Address
If your modem router is unable to access the Internet, and your Internet LED is green, you 
should determine whether the modem router is able to obtain an Internet IP address from the 
ISP. Unless you have been assigned a static IP address, your modem router requests an IP 
address from the ISP. You can determine whether the request was successful using the 
browser interface.
To check the Internet IP address from the browser interface: 
1. 
Launch your browser, and select an external site such as 
.
2. 
Access the main menu of the modem router’s configuration at http://192.168.0.1. 
3. 
In the main menu, under Maintenance, select Router Status and check that an IP address 
is shown for the WAN port. If 0.0.0.0 is shown, your modem router has not obtained an IP 
address from your ISP.
If your modem router is unable to obtain an IP address from the ISP, the problem might be 
one of the following:
•     
If you have selected a login program, the service name, user name, or password might be 
incorrectly set. See the following section, 
•     
Your ISP might check for your computer’s host name. Assign the computer host name of 
your ISP account to the modem router in the browser-based Setup Wizard.
•     
Your ISP allows only one Ethernet MAC address to connect to Internet, and might check 
for your computer’s MAC address. In this case, do one of the following:
-
Inform your ISP that you have bought a new network device, and ask them to use the 
modem router’s MAC address.
-
Configure your modem router to spoof your computer’s MAC address. This can be 
done in the Basic Settings screen.
