Not all they're cracked up to be!

Was super exited about upgrading our wireless throughout the house...Definitely does not give you 6000 sq ft coverage...my old Netgear router was much much better...the unit connected to my pc is only on the other side of the wall to my smart tv but we have far more buffering. Another 8' from the TV when working on my laptop I keep losing my signal. Have not had time to reach out to tech support, but overall am very disappointed as there is no improvement whatsover.
