I have my Nighthawk Router located downstairs. I no longer need to use an extender upstairs to help out with the signal. The Nighthawk Router is well designed and very strong.
I wanted to improve my WiFi coverage at home. This router did it in a snap. While the setup takes a bit longer than one would like, its detailed and you don't have to go back and tweak things for the best performance. I love having an app on my phone to quickly run my router, pause WiFi to specific devices, and easily swap devices between 5Ghz and 2.4Ghz bands automatically for best performance.
The Nighthawk is a difference maker for a large family with way too many gadgets. Connectivity is never an issue and my download speed speed went from 25Mbs to 110Mbs regardless if there are 2 gadgets connected or 6!
