Hey I was wondering what I should get... My router is located downstairs and I don't have wifi upstairs. But I have ethernet at every room upstairs. I'm trying to get a strong signal of wifi upstairs, should I get an acces point or what is the best and cheapest way to get wifi upstairs? I don't realy want to place repeaters at some rooms because that can get expensive quickly. I was wondering if there was a device that will output wifi signal when i put my ethernet cable in.
