I need a router that has better range than my D-Link DIR 655 for 2.4 GHz n for use with a couple of Chromecast devices in seeming dead spots. I'll be updating some other devices soon (iPad, iPhones, MacBook) to ones with ac receivers, so the router should also be ac and 5 GHz capable. I likely can use my current router as an access point to get rid of the dead spots, if my wife agrees to having it in the living room. But I can't count on that, and would like to have the best range on the main router for 2.4 GHz.
