What command are you using?

My.Computer.Network.IsAvailable works fine for me, although I just have
a single connection to a LAN.

You could always ping a few popular addresses to see if you have an
Internet connection. E.G www.google.com, www.microsoft.com,
www.yahoo.com its unlikely that they will all be down at the same time.

You could send a webrequest in a try/catch statement, if it throws an
exception then there is a problem connecting to the internet and you are
not connected.

Also not having an active Internet connection doesn't mean that you are
not connected to a Network.

I assuming you mean My.Computer.Network.IsAvailable()? If so I
wouldn't use it to determine and internet connection, but rather I
would use My.Computer.Network.Ping("www.google.com") - It will return
true only if the ping goes through - and not just if the computer is
talking to a network.

Thanks,

Well, except for microsoft.com - I believe it's servers are configured
to refuse ping requests.

Cool, didn't know that.
 
The problem isn' t solved.
Notice that i have several servers on my PC, does that change the
connection ?

You mean it's pinging fine? Even when not connected?

I don't understand either?


Private Funtion IsConnectedToInternet() as Boolean
Try 'Not sure if this is necessary
If My.Computer.Network.Ping("www.google.com") = False Then
If My.Computer.Network.Ping("www.yahoo.com") = False Then
'NOT CONNECTED TO THE INTERNET
Return False
End If
End If
Catch Ex as Exception
'SOMETHING WRONG HAPPENED NOT CONNECTED
Return False
End Try
'YOU ARE CONNECTED TO THE INTERNET
Return True
End Function

Or

Private Function IsConnectedToInternet() As Boolean
Return My.Computer.Network.Ping("www.google.com")
End Function

Does that not solve your problem?
 
No it don't ping
but my.computer.network.isavailable = true even when I'm not connected

I don't think you understood me then - I said to not use
Network.IsAvailable but to use Network.Ping. Networks are different
than internet connections - so Network.IsAvailable will not always
work.
