I have three Powerline adapters model number TL-PA8010P and originally one was connected to the router and one each to this laptop and my wifes laptop.She has  now changed her laptop so I am not using a adapter at present on her laptop.I just have the one connected to the router and the one connected to this laptop.The problem is I only sem to get two lghts lit on both adapters the top light and the bottom light.What do I need to do to get all three lights lit up do I have to pair the two adapters up again.I seem unable to remember how they are paired up.On this form it asks for the Hardware version and the Firmware Version where do I find that information.Can someone please help.Thanks a lot.
