I have a NetGear Powerline Ethernet Adapter with a extension. (It plugs into the wall but has the same power port so you don't lose an outlet.) My router is about 80-100 feet away and whenever I plug in both ends they show up orange on the power line. I tried it in the same room as were it was plugged in and got fantastic speeds. Then I moved it to were I wanted and it was orange and I was getting 2 Mbps compared to 75 in the other room. Is there something wrong with the adapter (I bought them about 2 and a half years ago.) But if they are 80-100 feet room by room shouldn't they work?
