I need to get internet to both my Zgemma and my android box preferably at the same time without have to plug in and out wires all the time. I have home plugs and I got an RJ45 splitter (Cheap from ebay) but only one side of it works, as in I'm having to plug in which ever device I want to use to get internet to it. I bought two of these and both are the same so I was wondering am I just unlucky and both are faulty or is what I want to do possible at all?
