Monitor Knowledgebase

Summary

This monitor generates an alert when Windows® detects that the network adapter has been disconnected from the network and no longer has network connectivity.

If the computer has only a single network adapter, this alert arrives only after network connectivity has been reestablished. In this case, you can resolve the alert without taking any additional action.

If the computer has multiple network adapters, the alert may arrive before network connectivity for the effected adapter has been reestablished. However, remote clients and applications may still have difficulty accessing resources on the computer despite the other adapter or adapters. In addition, the local computer may not be able to access some network resources.

Causes

Your computer's network adapter lost its connection to the network.

The adapter's connection to the network can be lost if you remove a network cable from your network adapter or if you are roaming between wireless access points with a mobile system. Other possible causes include network issues, firewall issues, or a malfunction of the network adapter or its driver.

Resolutions

If your computer is connected to the network by cable, confirm that the cable is plugged in properly. If you have a wireless network connection, confirm that you have a signal and the proper credentials for the wireless network.

If the network connection is working properly, check the following possible causes and take corrective action:

  • The network is down.

  • The firewall on your computer is blocking network broadcast traffic.

  • Your computer's network adapter or driver is not functioning correctly.
