Hello - I've just purchased a single Deco 5 (1300) unit thinking I could set it up and place it in the kitchen where at the moment our Virgin Media router just wont reach i.e there is zero wifi there. I thought this single Deco 5 unit could be set up and then placed in the hallway to push the wifi signal into the kitchen. I've tried to set up the deco unit but as soon as you take out the ethernet cable from the back of the Virgin Media unit then it all goes to red light and stops functioning. Have I bought the wrong device???? It seems I need to keep one Deco unit permanenetly connected via ethernet cable and then I can have a second unit positioned eslewhere in the flat that will push the wifi signal to the back of the house? I couldnt see anywhere on the tp-link site which suggested you need to purchase 2 units to achieve this outcome. As you can tell I have zero IT knowledge, so any responses please assume you are dealing with an 8 year old! Many thanks, Steve
