•Make sure that your browser has Java, JavaScript, or ActiveX enabled. If you are using Internet Explorer, click Refresh to be sure that the Java applet is loaded. •Try quitting the browser and launching it again. •Make sure that you are using the correct login information. The factory default login name is admin, and the password is password. Make sure that Caps Lock is off when you enter this information. Troubleshoot the Internet Connection If your modem router is unable to access the Internet, check the ADSL connection, then the WAN TCP/IP connection. ADSL Link If your modem router is unable to access the Internet, first determine whether you have an ADSL link with the service provider. The state of this connection is indicated with the Internet LED. ADSL Link LED Is Green If your ADSL link LED is green, you have a good ADSL connection. You can be confident that the service provider has connected your line correctly and that your wiring is correct. ADSL Link LED Is Blinking Green If your ADSL link LED is blinking green, your modem router is attempting to make an ADSL connection with the service provider. The LED should turn green within several minutes. If the ADSL link LED does not turn green, disconnect all telephones on the line. If this solves the problem, reconnect the telephones one at a time, being sure to use a microfilter on each telephone. If the microfilters are connected correctly, you should be able to connect all your telephones. If disconnecting telephones does not result in a green ADSL link LED, there might be a problem with your wiring. If the telephone company has tested the ADSL signal at your network interface device (NID), then you might have poor-quality wiring in your house. ADSL Link LED Is Off If the ADSL link LED is off, disconnect all telephones on the line. If this solves the problem, reconnect the telephones one at a time, being sure to use a microfilter on each telephone. If the microfilters are connected correctly, you should be able to connect all your telephones. If disconnecting telephones does not result in a green ADSL link LED, check for the following: •Check that the telephone company has made the connection to your line and tested it. •Verify that you are connected to the correct telephone line. If you have more than one phone line, be sure that you are connected to the line with the ADSL service. It might be necessary to use a swapper if your ADSL signal is on pins 1 and 4 or the RJ-11 jack. The modem router uses pins 2 and 3. 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 Internet Setup screen is 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, see if the modem router can 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. 1.Launch your browser, and select an external site such as 2.Access the main menu of the modem router’s configuration at 3.Click the Advanced tab 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, Troubleshoot PPPoE or PPPoA . •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. Troubleshoot PPPoE or PPPoA 1.Access the main menu of the modem router at 2.Select Maintenance > Router Status. 3.Click the Connection Status button. If all of the steps indicate OK, your PPPoE or PPPoA connection is up and working. If any of the steps indicates Failed, you can attempt to reconnect by clicking Connect. The modem router continues to attempt to connect indefinitely. If you cannot connect after several minutes, you might be using an incorrect service name, user name, or password. There also might be a prov...
