I have an Orange Livebox.
I have a PC wired to the red ethernet port - everything is fine with that.
I have several devices that are paired to connect wirelessly ( 2 laptops / iphone / TV dongle ) - everything is fine with them.
I have wired up the yellow ethernet port and any device I connect to this is given an IP address by the livebox but the connected device seems unable to see the internet!! UPnP is enabled in the Livebox.
What is going wrong?
