I am no longer able to access the Internet.

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

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:

Check the LEDs

  1. Is the router's Power LED lighted?
  2. Is the router's System LED blinking at the steady rate of once per second?
  3. Is one of the router's WAN LEDs lighted?
  4. Is the router's LAN LED that corresponds to the LAN port connected to your computer lighted?
  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

Ping the router as follows:

  1. Click Windows Start > Run.
  2. In the Run dialog box
  3. Type Ping and press Enter.

Did the Web User Interface appear?


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.

If your WAN type is dynamic,

  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.
