I was using an old dual-band N600 router that was new out-of-the-box several years ago. Recently the old Netty was not doing so well and my WiFi speeds were rather slow, the connections were dropping and the Router itself was starting to feel hot to the touch. After some research, I chose this new Nighthawk router and my entire home WiFi has benefited from it! Speed went from 70.9 up to 149 download speed. In addition, there's no need for 2 broadcasted SSIDs for 2.4Ghz and 5Ghz. It can all be combined into one SSID to let the router and the device decide which would work best. Lastly, I kept the same SSID and password so all the previous devices would automatically connect. Everything runs great!
I've been having issues with my internet for awhile. My service guy told me this was the new router to purchase, and he was right. Extremely easy to set up. Great internet speeds since. I highly recommend.
