The router has me running at peak performance. The draw back is the size and orientation of the unit. After a slight modification I was able to lay down the unit to fit in more "clean" looking areas.
I use this with Optimum and the monthly savings of not paying their modem fee is well on its way to covering the cost of this duel modem/router. It is much faster and more reliable than my ISP's stock hardware. I highly recommend it.
