We recently replaced an aging N600 (C3700) with the Nighthawk AC1900 (C7000v2) and are thoroughly pleased with the upgrade. Its sleek design and seamless setup are chief factors for our satisfaction.
We have 3 TVs that all stream, one gaming system and 1 cell phone that uses wifi. It seems to handle it all right. We have the highest cable internet speed possible. Sometimes the SuperBox loses connection...not sure if that is due to the router though.
I like the ability to quickly deny access to devices...helpful tool for parenting!
Had to replace modem/router and bought the Netgear Nighthawk AC1900 . What a difference that made - everything is working great . I highly recommend this unit !
