Do this test: Bug Report instructions & sample image Is the result True/False?

If false then you have a firewall issue. Which is the same as the brick wall icon. But there's no telling what is causing it. The issue here is that your modem/router does have an internal NAT firewall. So either you enable UPnP on it if it has that ability or else, manually port forward. Once you do this I suspect the brick wall will disappear. But you'll need to re-open LW for the changes to take effect. Also, some modems you need to reboot to save changes. I don't know about your model. If yes, you'll probably see such a warning.
