I want to check internet connection is available by vb.net code

What I have tried:

Public Function isInternetConnected(Optional pUrl As String = "http://www.google.com") As Boolean

    Try
        Using client = New WebClient()
            Using stream = client.OpenRead(pUrl)
                Return True
            End Using
        End Using
        Return IsConnectedToInternet(pUrl)
    Catch ex As Exception
        Return IsConnectedToInternet(pUrl)

    End Try
End Function

This code sometimes returns false when internet connection is available.

You haven't shared the code that actually does the check - i.e. IsConnectedToInternet

There's no 100% working solution for this, but you can try:

VB

'reference to System.Net and System.Net.NetworkInformation is required!
Function IsInternetConnected() AS Boolean

	Return New Ping().Send("www.google.com").Status = IPStatus.Success

ENd Function

It works correctly in most cases.
