I'm in the process of upgrading my BT Broadband to Fibre Optic and ahead of the actual switchover I received a BT Hub 5. I live in a part of the house where Wireless is not great and there use Powerline plugs to connect to the internet. With my 2009 Mac Mini (RAM 8GB) and El Capitan I managed to connect both wirelessly and via the TP-Link AV500 Powerline plug. But when I try to connect to the internet on my Bootcamp Windows 7 partition, I cannot get the computer to talk with the Powerline plug and whenever I fiddle around, come up with the message, "Local Area Connection doesn't have a valid IP configuration." When I upgraded from BT Hub 3 to Hub 4, I never had any problems so don't know what's going on and Networking is definitely my weakest area of understanding. I don't know anything to be honest. Can anyone advise me please?
