The best & fastest routers on the market today are equipped with these two new technologies: tri-band AC5400 and MU-MIMO. Yes, jargon! The important thing to know is that they result in full bandwidth wi-fi speeds up to 5334Mbs. Psycho fast. The other thing to know is that Linksys just packed both of these technologies into their new EA9500 model router for a very nice price.
