To check whether a computer has a working connection

  • Determine whether the IsAvailable property is True or False. The following code checks the property's status and reports it:

    If My.Computer.Network.IsAvailable = True Then
        MsgBox("Computer is connected.")
    Else
        MsgBox("Computer is not connected.")
    End If
    

    This code example is also available as an IntelliSense code snippet. In the code snippet picker, it is located in Connectivity and Networking. For more information, see How to: Insert Snippets Into Your Code (Visual Basic).
