Appendix: Checking that the network adapter card is enabled
In the Control Panel... Double-click on the « System » icon. Go to the « Hardware » tab and click on « Device Manager ». In the « Network Adapter » section of the list, you will see an adapter with a red « X ». Right-click on the adapter and click « Enable ». If the listed adapter does not have a red « X » , it is enabled.
Your network cable (RJ-45) may also not be plugged in properly. Check both ends of the cable to make sure that it is properly plugged into the modem as well as into your computer’s network adapter card. Unplug and replug both ends to be sure that the connection is being made.
