Error 678

This issue may occur on Windows XP computers using bridged DSL modems when either the computer or modem are not communicating. Use the steps below to correct this error:

Before you begin -- Reboot both your DSL modem as well as your computer. This will often resolve DSL or Broadband related issues without further troubleshooting. If you continue to receive this error message, continue through the following steps.

A. Make sure the network card is enabled:

  1. Go to Start > Connect To > Show All Connections.
  2. Right click on the Local Area Connection icon.
  3. If the first word on the menu says Enable, click on it to turn on the network card.
  4. If the first word on the menu says Disable, this indicates the LAN is already enabled, go to the next step.

B. Reverse the Ethernet cable, or try a new cable.

C. Is there more than one network card installed? If so, make sure the Ethernet cable is plugged into the correct card.

D. Reset the networking parameters:

  1. Click on Start, and then Run.
  2. Type Command in the Run window, and then click OK.
  3. In the Command Prompt window, type the following command:
    netsh interface ip reset log.txt
    Press Enter.
  4. Type Exit
  5. Reboot both the computer and the DSL modem.

E. Adjust the connection type of the Ethernet card:

  1. Go to Start and right click on the My Computer icon.
  2. Select Properties on the menu.
  3. Select the Hardware tab and click Device Manager.
  4. Locate Network Adapters on the list, and click the + next to it.
  5. Double click on the network card listing.
  6. Click the Advanced tab at the top.
  7. On the left, there should be a small window with a listing of something like Link Speed. Click on that, then choose 10 Full Mode or 10BaseT.
  8. Click OK when complete and close Device Manager.

F. If the above suggestions do not work, the network card may not be compatible with the modem, or the network card needs updated drivers. Using a router with your Westell modem instead of connecting directly to the computer may also fix the issue.
