Could someone please explain when the functions NetworkInterface.Bind(), Rebind, Unbind should be used?  I have the following code that I use to find nearby access points:

Dim NoAPs As Boolean = True
Dim ReturnValues As AccessPointCollection

        While (NoAPs)
            AddStatus("Searching for the network...", True)
            If CopyProgressBar.Value >= CopyProgressBar.Maximum Then
                Exit Sub
            End If
            Threading.Thread.Sleep(2000)
            _ZeroConfigInterface.Refresh()           
            ReturnValues = _ZeroConfigInterface.NearbyAccessPoints
            If ReturnValues.Count > 0 Then
                NoAPs = False
            End If
        End While

I USUALLY find the nearby access points, but not always.  Sometimes this while loop will time out. I am grasping at straws and hoping the Bind function will make a difference.  Anyone have any pointers?

Bind is used to to tell NDIS to attach to an adapter.  It would be used after an Unbind.  Typically you would do this when you make changes (like to the static IP address, DNS, etc) by doing an Unbind and Bind, or calling Rebind, which does both.
