  3. If your network includes a separate broadband modem, unplug the power cord from the broadband modem.
  4. Wait for about five seconds, and then plug the power cord into the wireless router (and broadband modem, if separate).
  5. Wait until all lights come on, and then reflect normal Internet and computer activity. If the lights on the broadband modem indicate a problem, refer to the following list of options for help:
    • If all lights are off after reconnecting the power, check the power source by plugging the power cord into another power outlet. Service or replace your broadband modem if it cannot be turned on.
    • If only the power light is on and the remaining activity lights are off or show no activity, a network connection is not being detected. Make sure the cable carrying the Internet signal is connected to the broadband device. Ensure Internet cables coming into your residence have not been damaged or disconnected. You might need to contact your Internet service provider if other people in your area are also experiencing Internet outages.
    • If the Internet or Online light consistently blinks and does not indicate an online connection is available, the problem likely resides with your Internet service provider. Either wait until service is restored or contact your Internet service provider for further assistance.
  6. Turn on your computer and wait until Windows opens. If you are using a notebook computer, perform a hard reset at this time.
    Wait until Windows automatically connects to your wireless Internet connection.
  7. Right-click the network connection icon in the system tray, and select Network and Sharing Center.
  8. Select Manage network connections.
  9. Verify the status of the wireless network.
