The router does its job. Only concern is it promotes gigabit speed, though I am recieving considerably less. Have yet to troubleshoot to see if it is my ISP, the ethernet cable, or the router.
I paired my EX6250 with my newly purchase Nighthawk as WIFI extender. Our Nighthawk is located in our basement and I needed to boost the signal to reach the upper floors in our home (just like the picture in the EX6250 literature describes the use of the device). The pair works perfectly! And the Nighthawk app on my phone lets me manage the entire system from anywhere, anytime.
