Checking for internet connection

[c1223]

I can't seem to find in the documentation how one can check whether there is an active internet connection available. I was looking at the QNetworkSession class but can't seem to work it out.

Thanks

Maybe through this?

Thanks. I did try that. Returns true even when there isn't any connectivity.

I think the only way is to try to connect to a server at a well-known address.

Right, depends on what kind of information the thread starter was looking for.
Obviously if the question is "can I reach a specific host" then the only way to determine that is to try to connect to it.

The network configuration classes only tell you if there is even a point in trying that, i.e. if there is no connected network interface then any attempt will fail locally already.
