I connected my AV600 into my router and the other in my garage. Everything worked fine. The upload and download speed was almost identical to my house. Then I had extra sockets fitted in my garage and a new consumer unit installed. Now, my wi fi no longer works. My devices connect to the network but no internet. Also the Powerline light no longer comes on. If I unplug it and plug it back in in the same room as my tourer, it all works fine but when I take it back to the garage, the Powerline light doesn't light up again. Is the new consumer unit possibly the cause?
