Trying to find a good networking solution because I am in a long house and the cable/wired router is in the front and I am in the back and worried about range speed of Wifi. Looking at these Powerline adapters: http://www.bestbuy.com/site/Actiont...-Kit/5215483.p?id=1218625358741&skuId=5215483 or http://www.bestbuy.com/site/Tp-Link...75570165&skuId=4359873&st=powerline&cp=4&lp=5 Anyone use these or Powerline? How is Powerline speed? Powerline seems cheaper then a good N router and for my house might be more stable, right?
