I am no longer able to access the Internet.

When your computer connects to the Internet, a number of devices must work together:

  • Your computer must connect to your router.
  • Your router must connect to your modem.
  • Your modem must connect to your Internet Service Provider (ISP)

Your Internet access might be failing in any of these devices or in any of the connections between them. To help you find the source of the problem and correct it, the instructions in this section will guide you through three major troubleshooting steps:

  • Checking the devices' LEDs
  • Checking the router and its connections
  • Checking the modem and its Internet connection

Check the LEDs

  1. Is the router's Power LED lighted?
    • If yes, continue with the next LED checking step.
    • If no, be sure that your router is plugged in to a working power source.
  2. Is the router's System LED blinking at the steady rate of once per second?
    • If yes, continue with the next LED checking step.
    • If no, reboot the router by unplugging its power supply and plugging it in again. If the System LED still does not blink steadily at the rate of once per second, the router may have failed. Contact U.S. Robotics Customer Support.
  3. Is the router's WAN LED lighted?
    • If yes, continue with the next LED checking step.
    • If no, the router does not have access to the Internet, so neither will your computer. To find out why your router cannot access the Internet, check your router to modem connection.
  4. Is the router's LAN LED that corresponds to the LAN port connected to your computer lighted?
    • If yes, continue with the next LED checking step.
    • If no, the router does not have access to your computer and cannot pass data between the computer and the Internet. Check your computer to router connection.
  5. Do your modem's power and status LEDs indicate a connection? (Refer to your modem's documentation for information on its indicators.)

Check the Router and Its Connections

This section will guide you through the steps of determining whether your problem resides in one of the following segments of the connection between your computer and the Internet:

  • Computer to Router Connection
  • Router
  • Router to Modem Connection

Router to Modem

Ensure that both ends of the cable connecting your router to your modem are connected securely. Ensure that the modem has power and is turned on. If you still do not have access to the Internet, the problem probably is in the modem or its connection to your Internet Service Provider. Check the Modem and its Internet connection.

Check the Modem and Its Internet Connection

  1. Ensure that your modem is connected to the wall jack and that both ends of the cable are connected securely.
  2. Reboot the modem. Your modem may have a power switch or reset button, or you may need to unplug the modem's power adapter and plug it in again. For modem rebooting instructions, consult your modem's documentation or contact your Internet Service Provider.

If your WAN type is Dynamic IP Address or Dynamic IP Address with Road Runner Session Management,

  1. Open the router's Web User Interface Status page, click Release, then click Renew.
  2. After the router has finished renewing its WAN IP address, the Status page should identify the WAN IP address.
    • If the router has a WAN IP address, try to access the Internet. If you still do not have access to the Internet, the problem is probably with your modem or your Internet Service Provider. Contact your ISP for further troubleshooting assistance.
    • If the router does not have a WAN IP address, the problem is probably with your modem or your ISP. Contact your ISP for further troubleshooting assistance.

If your WAN type is Dynamic IP Address with Road Runner Session Management, PPPoE, or PPTP, verify that you entered the correct password on the router's Primary Setup page. If the password is correct and you cannot access the Internet, contact your ISP for further troubleshooting assistance.

If your WAN type is PPTP or PPPoE, open the router's Status page and click Connect. If you still cannot access the Internet, contact your ISP for further troubleshooting assistance.
